Description

Coolant input device and cooling material input method {COOLING ELEMENT INSERTING APPARATUS AND METHOD}

The present invention relates to a coolant input device and a coolant input method, and more particularly, to a coolant input device and a coolant input method that can easily cool the tail portion of the cast by injecting coolant into a mold.

Generally, the continuous casting process is a process of continuously casting a cast piece. Ladle transporting molten steel injects molten steel into tundish. The molten steel injected into the tundish is continuously injected into the mold through an immersion nozzle. When the molten steel whose surface is solidified in the mold is drawn to the lower side of the mold, cast pieces of various shapes such as slabs, blooms, and billets are manufactured.

At this time, whenever molten steel in the ladle is injected into the tundish, slag is mixed into the molten steel and flows into the tundish. The slag flowing into the tundish flows into the mold together with the molten steel at the time of completion of the course, and forms a slag layer on the molten surface of the mold, and forms a tail portion of the cast. However, the slag forming the tail portion of the cast steel may interfere with the solidification process of the molten steel. Therefore, when the cast piece reaches the lower side of the mold, a bleeding phenomenon may occur in which uncoagulated molten steel flows through the slag layer. Accordingly, there is a problem in that a safety accident occurs as the peripheral equipment is damaged by the unflowed molten steel.

In the related art, an operation of forcibly cooling the tail surface of the cast piece was performed to prevent this. For example, at the end of the casting, the casting speed was slowed down to smoothly cool the tail portion of the cast, or the driving roll for drawing the cast was stopped to stagnate the casting. However, in this case, it is impossible to remove all of the high-temperature slag in a short time, and there is a problem that the quality of the cast is adversely affected as the manufacturing of the cast becomes stagnant.

Alternatively, a metal piece, such as a chip or scrap metal, was put into the mold to force the solidified slag and molten steel in the tail portion of the cast steel, and then to draw the cast. However, in this case, since the worker approaches the mold and injects a piece of metal into the mold, there is a problem in that the risk of safety accidents increases, such as a worker getting burned due to the high temperature heat rising from the mold and the explosion of molten steel.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various different forms, and only the embodiments allow the disclosure of the present invention to be complete, and the scope of the invention to those skilled in the art is completely It is provided to inform you. To describe the invention in detail, the drawings may be exaggerated, and the same reference numerals in the drawings refer to the same elements.

1 is a view showing the structure of a casting facility according to an embodiment of the present invention. In the following, to understand the present invention, the structure of the casting equipment will be described.

Referring to FIG. 1, the casting facility may include a ladle 10, a tundish 20, a mold 30, a coolant input device, and a cooling table 40. At this time, the casting facility may be a continuous casting facility that continuously injects molten steel into the mold 30 and continuously draws the reaction solid from the lower portion of the mold 30 to obtain cast pieces such as billets, blooms, slabs, and the like.

The ladle 10 may be formed in a cylindrical container shape. The ladle 10 has an internal space to contain molten steel, and the upper portion can be opened. An injector 15 may be provided under the ladle 10. Therefore, molten steel stored in the ladle 10 may be injected into the tundish 20 through the injector 15.

The tundish 20 may be located below the ladle 10. The tundish 20 may be formed in a container shape in which molten steel can be stored. The upper portion of the tundish 20 may be opened, and an immersion nozzle 25 may be provided at the lower portion.

The immersion nozzle 25 may extend in the vertical direction. The immersion nozzle 25 may have an upper end connected to an outlet formed on the bottom surface of the tundish 20, and a lower end may extend toward the inside of the mold 30. Accordingly, molten steel introduced into the immersion nozzle 25 through the exit hole may be supplied into the mold 30.

In addition, a stopper (not shown) that opens and closes the outlet of the tundish 20 to control the flow rate of molten steel supplied to the mold 30 may be installed in the tundish 20. Accordingly, the amount of molten steel supplied to the mold 30 through the immersion nozzle 25 can be controlled by controlling the operation of the stopper.

Alternatively, a sliding gate (not shown) may be installed on the tundish 20 and the immersion nozzle 25. The sliding gate can control the opening degree of the moving path of the molten steel formed inside the immersion nozzle 25. Accordingly, the amount of molten steel supplied from the tundish 20 to the mold 30 may be controlled by controlling the operation of the sliding gate.

The mold 30 may be located under the tundish 20. The mold 30 is a frame that solidifies molten steel to determine the appearance of the metal product. The mold 30 may include two long side plates that are disposed to face each other, and two short side plates that are disposed to face each other between the two long side plates. A space in which molten steel is accommodated between the long side plates and the short side plates is formed, and the upper and lower portions of the mold 30 may be opened to form an opening. A path through which the coolant circulates may be formed inside at least some of the long side plates and the short side plates. Thus, the molten steel supplied into the mold 30 can be quickly solidified by taking away heat by the cooling water.

The coolant input device may be disposed on the upper portion of the mold 30. The coolant input device may input the coolant into the mold 30. The coolant can forcibly solidify the unsolidified slag and molten steel in the cast tail portion of the mold 30. Accordingly, it is possible to prevent the unsolidified molten steel from flowing out of the cast steel drawn to the lower side of the mold 30.

Cooling table 40 may be located on the lower side of the mold (30). The cooling table 40 may include a plurality of transport rollers 45 arranged while forming a movement path of the cast piece, and a coolant sprayer (not shown) that sprays cooling water to the cast piece moved by the transport roller 45. . Accordingly, the cooling table 40 may perform a series of molding operations while cooling the cast pieces drawn and moved from the mold 30.

2 is a view showing a structure of a coolant input device and a mold according to an embodiment of the present invention, and FIG. 3 is a view showing a structure of a coolant according to an embodiment of the present invention.

Referring to FIG. 2, the coolant input device 100 according to an embodiment of the present invention is a coolant input device that can input the coolant 110 into the opening of the mold 30. The coolant input device 100 includes a path part 120 and a blocking part 130.

The coolant 110 is introduced into the mold 30 and serves to solidify by forcibly cooling the surface of the cast tail portion. The coolant 110 may be formed of a steel material. The coolant 110 may extend in the extending direction of the mold 30 opening. Accordingly, the coolant 110 may have a flat shape that is the same as the flat shape of the cast tail portion. The coolant 110 may be formed smaller than the opening of the mold 30. Therefore, the coolant 110 is introduced through the opening of the mold 30, so that the entire upper portion of the cast tail portion can be uniformly cooled.

In addition, at least a portion of the coolant 110 may be formed in a cylindrical shape. That is, as shown in Fig. 3 (a), the coolant 110 may be formed in a cylindrical shape to be easily rolled. Thus, the coolant 110 can be easily rolled along the inclination of the path portion 120 and introduced into the opening of the mold 30.

The coolant 110 may be formed in a hollow shape. For example, the coolant 110 may have an inner space and be formed in a pipe shape with both sides open. Accordingly, unsolidified molten steel of the cast steel may be introduced into the coolant 110 through both open sides of the coolant 110. Therefore, the coolant 110 does not float on the molten steel and can sink into the molten steel.

In addition, a plurality of through holes 110a may be provided on the entire circumference of the coolant 110. Accordingly, irrespective of which portion of the coolant 110 contacts the molten steel, the unsolidified molten steel of the tail portion of the cast steel can be easily introduced into the coolant 110 through the through holes 110a. Therefore, the coolant 110 does not float on the unsolidified molten steel, and sinks more effectively into the unsolidified molten steel, so that the unsolidified molten steel can be easily cooled.

At this time, an insertion groove (not shown) may be provided around the coolant 110. The insertion groove may be formed in a ring shape. The path member 123 provided in the path portion 120 may be fitted into the insertion groove. Therefore, the path member 123 serves as a rail, so that the coolant 110 can stably move along the slope without leaving the path member 123.

On the other hand, as shown in Figure 3 (b), the coolant 110 may be adjustable in length in the extending direction. The opening length of the mold 30 may vary according to the type of cast produced. Accordingly, the length of the coolant 110 can be adjusted to match the length of the mold 30. For example, the coolant 110 may include a first body 111 and a second body 112. The overall length of the coolant 110 may be adjusted by controlling the degree to which the first body 111 and the second body 112 overlap each other. At this time, through holes 110a may be provided on the surfaces of the first body 111 and the second body 112.

The first body 111 may be formed in the form of a cylindrical pipe. Accordingly, a space through which molten steel can be introduced may be formed in the first body 111.

The second body 112 may be formed in the form of a cylindrical pipe. The inner diameter of the second body 112 may be greater than or equal to the outer diameter of the first body 111. Accordingly, the first body 111 may be movably fitted inside the second body 112. Accordingly, when the degree to which the first body 111 fits inside the second body 112 is adjusted, the length of the coolant 110 may be adjusted.

In addition, one or a plurality of second bodies 112 may be provided. For example, the second body 112 is provided with a pair may be installed on both sides of the first body 111. Accordingly, a pair of second bodies 112 may move on both sides of the first body 111 in the extending direction of the opening of the mold 30. Therefore, it is possible to increase the range in which the length of the path part 120 can be adjusted.

When the outer diameters of the first body 111 and the second body 112 are different from each other, the first body 111 and the second body 112 of the coolant 110 respectively contact the path portion 120 , Coolant 110 may be seated in an inclined state to either side. Accordingly, when the coolant 110 is moved on the path portion 120, it may be biased to one side and rolled, and a problem may be caused that it is incorrectly or is not input into the opening of the mold 30.

To solve this problem, when the coolant 110 is seated on the path portion 120, a pair of the second body 112 is in contact with the path portion 120, the first body 111 is a path It may not be in contact with the unit 120. Since the outer diameters of the second bodies 112 are equal to each other, the coolant 110 may be seated while maintaining the horizontality on the path portion 120. Thus, when the coolant moves along the inclination of the path portion 120, the coolant 110 may move in a straight line along the inclination without being biased to either side. Therefore, the coolant 110 can be stably introduced into the opening of the mold 30.

However, the present invention is not limited thereto, and the second body 112 is inserted into the first body 111 so that only the first body 111 contacts the path portion 120 and the second body 112 is routed. It may not be in contact with the unit 120. The structure and shape of the coolant 110 may also be various, without being limited thereto.

4 is a view showing a structure of a path part according to an embodiment of the present invention, and FIG. 5 is a view showing an operation structure of a blocking part according to an embodiment of the present invention. Hereinafter, a path portion and a blocking portion according to an embodiment of the present invention will be described.

Referring to (a) of FIG. 4, the path part 120 is disposed on the upper part of the mold 30. For example, it may be disposed on the upper side of the long side plate of the mold (30). The path part 120 forms a path of the coolant 110 inclined downward toward the opening of the mold 30. Accordingly, when the coolant 110 rolls along a path formed by the coolant 110, the coolant 110 moves toward the opening of the mold 30 and may be introduced into the mold 30. The path part 120 includes a support member 121, a connection member 122, and a path member 123. The path part 120 may further include a fixing member 124 and a guide member.

The support member 121 may be formed in a triangular plate shape. The support member 121 may be seated on the upper surface of the mold 30. A plurality of support members 121 may be provided. For example, a pair of support members 121 may be provided to be spaced apart from each other in the extending direction of the coolant 110. The distance from which the support members 121 are spaced apart from each other may be longer than or equal to an extended length of the opening of the mold 30. However, the structure and shape of the support member 121 are not limited to this and may be various.

The connecting member 122 may extend in the extending direction (or left and right direction) of the coolant 110. One end (or the left end) of the connection member 122 is connected to the support member 121 located on one side (or the left end), and the other end (or the right end) is supported on the other side (or, the right end) ( 121). The connecting member 122 may be located below the inclined surface of the path member 123. Thus, the connecting member 122 may not be located on the inclined surface of the path member 123, and may not prevent the coolant 110 from moving along the inclined surface of the path member 123.

In addition, the connecting member 122 may include a main connecting bar 122a. The main connecting bar 122a may be formed in a circular bar shape. The main connecting bar 122a forms a path through which the path member 123 moves. Thus, the path member 123 is fitted to the main connection bar 122a and can move along the extension direction of the main connection bar 122a.

Meanwhile, the connecting member 122 may further include an auxiliary connecting bar 122b. The auxiliary connection bar 122b may be formed in a circular bar shape. The auxiliary connection bar 122b may be spaced apart from the main connection bar 122a. For example, the main connecting bar 122a and the auxiliary connecting bar 122b may be disposed along the inclination of the path part 120, and the main connecting bar 122a may be positioned above the auxiliary connecting bar 122b. You can. Therefore, since the main connecting bar 122a and the auxiliary connecting bar 122b together form a path through which the path member 123 moves, the path member 123 does not shake, and the left and right directions between the support members 121 Can stably move. In this case, one or a plurality of auxiliary connection bars 122b may be provided.

In addition, the connecting member 122 may be provided with a plurality of insertion grooves 122c spaced from each other in the extending direction of the coolant 110. The insertion groove 122c may be disposed toward the upper portion, and a fixing member 124 passing through the path member 123 may be inserted. The insertion groove 122c may be formed on at least one of the main connecting bar 122a and the auxiliary connecting bar 122b. However, the structure and shape of the connecting member 122 are not limited thereto, and may be various.

The path member 123 may be formed in a triangular plate shape. That is, the path member 123 may increase the length in the vertical direction toward the outside of the mold 30 from the opening. Accordingly, the upper surface of the path member 123 may have a slope. The upper surface of the path member 123 may contact the coolant 110 and may form a path through which the coolant 110 moves.

In addition, the path member 123 may be installed to be movable in the extending direction (or left and right direction) of the coolant 110 to the connection member 122. Accordingly, the path member 123 may move left and right between the support members 121. A hole may be formed in the side surface of the path member 123. The diameter of the hole may be formed to be greater than or equal to the diameter of the connecting member 122. The connection member 122 may pass through the hole of the path member 123, and the path member 123 may move along the extending direction of the connection member 122. When the connecting member 122 includes both the main connecting bar 122a and the auxiliary connecting bar 122b, the path member 123 has holes corresponding to the positions of the main connecting bar 122a and the auxiliary connecting bar 122b Can be provided.

An insertion hole 123a may be formed on an upper surface of the path member 123. The insertion hole 123a may be arranged according to the position of the connecting member 122. The insertion hole 123a may extend from an upper surface of the path member 123 to a hole through which the connection member 122 penetrates. Thus, depending on the position of the path member 123, the insertion hole 123a of the path member 123 and the insertion groove 122c of the connection member 122 may communicate with each other. Therefore, when the fixing member 124 penetrates through the insertion hole 123a and fits into the insertion groove 122c, the path member 123 may not be moved from side to side and may be fixed.

In addition, a mounting groove 123b may be formed on the upper surface of the path member 123. The mounting groove 123b may be formed by digging downward from the upper surface of the path member 123. The mounting groove 123b forms a space in which the blocking unit 130 can be installed. The mounting groove 123b may be located in the central region of the path member 123. Accordingly, the blocking unit 130 installed in the mounting groove 123b blocks the middle of the path in which the coolant 110 moves, so that the coolant 110 does not move on the path member 123 and can remain stationary. .

A plurality of path members 123 may be provided. For example, a pair of path members 123 may be provided. The distance may be adjusted while moving between the path members 123 and the support members 121. Accordingly, according to the length of the coolant 110 whose length is adjusted, the distance between the path members 123 may be adjusted by moving the path members 123. That is, when the length of the coolant 110 decreases, the gap between the path members 123 may be narrowed, and when the length of the coolant 110 increases, the gap between the path members 123 may be widened. However, the structure and shape of the path member 123 and the number provided may not be limited to this, and may vary.

The fixing member 124 serves to fix the position of the path member 123. The fixing member 124 may extend in the vertical direction. The fixing member 124 may be formed longer in the vertical direction than the insertion hole 123a of the path member 123. Accordingly, the fixing member 124 may penetrate the path member 123 and fit into the insertion groove 122c of the connection member 122. When the fixing member 124 is inserted into the insertion hole 123a and the insertion groove 122c, the path member 123 is fixed because it cannot move from side to side, and the fixing member 124 is inserted into the insertion hole 123a and the insertion groove 122c ), The path member 123 can move left and right.

4 (b), the guide member 125 may be formed in a square plate shape. The guide member 125 may be formed to protrude more upward than the path member 123. Accordingly, the guide member 125 may form partition walls on one side or both sides of the path of the coolant 110 formed by the path member 123. The portion facing the connecting member 122 of the guide member 125 may contact the coolant 110. Therefore, when the coolant 110 moving along the upper surface of the path member 123 tries to escape the path, it may be prevented from coming out of the path by contacting the guide member 125.

In addition, the guide member 125 may be installed to be movable in the extending direction (or left and right direction) of the coolant 110 to the connection member 122. The guide member 125 may be located between the support member and the path member. Thus, the guide member 125 can move left and right between the support member 121 and the path member 123. A hole may be formed in the side surface of the guide member 125. The diameter of the hole may be formed to be greater than or equal to the diameter of the connecting member 122. The connecting member 122 may penetrate the hole of the guide member 125, and the guide member 125 may move along the extending direction of the connecting member 122. When the connecting member 122 includes both the main connecting bar 122a and the auxiliary connecting bar 122b, the guide member 125 has holes corresponding to the positions of the main connecting bar 122a and the auxiliary connecting bar 122b Can be provided.

One or a plurality of guide members 125 may be provided. For example, a pair of guide members 125 may be provided. One of the guide members 125 may be located between the support member 121 and the path member 123 located on the left side, and the other one may be located between the support member 121 and the path member 123 located on the right side. The gap between the guide members 125 may be adjusted to the length of the coolant 110. At this time, the distance between the guide members 125 may be longer than the length of the coolant 110. Therefore, the coolant 110 can move between the guide members 125, and the guide members 125 can prevent the coolant 110 from deviating from the path on both sides.

Referring to Figure 5, the blocking unit 130 serves to block or open the path of the coolant 110. The blocking unit 130 may be installed in the path unit 120. The blocking unit 130 includes a stopper 131 and a driving member 132.

The stopper 131 may be formed in a rod shape extending up and down. The path member 123 is installed to be movable up and down. When the stopper 131 moves upward, it may protrude upward from the upper surface of the path member 123, and when the stopper 131 moves downward, it may move into the mounting groove 123b provided in the path member 123. . Accordingly, when the stopper 131 moves upward as shown in (a) of FIG. 5, the coolant 110 may be prevented from rolling in contact with the coolant 110, and the stopper 131 as shown in FIG. 5 (b) When moving downward, the stopper 131 does not block the path of the coolant 110 so that the coolant 110 rolls along the inclination of the path member 123 and can be introduced into the mold 30. However, the structure and shape of the stopper 131 is not limited thereto, and may be various.

The driving member 132 serves to move the stopper 131 up and down. The driving member 132 may be installed in the mounting groove 123b provided in the path member 123. The driving member 132 may be connected to the lower portion of the stopper 131 to move the stopper 131. For example, the driving member 132 may be a cylinder. Therefore, the stopper 131 can be pushed upward or moved downward by the pressure of the fluid such as air or hydraulic pressure. Accordingly, the operator can control the operation of the driving member 132 to inject the coolant 110 seated on the path member 123 into the mold 30 at a desired time. However, the method in which the driving member 132 moves the stopper 131 up and down is not limited thereto, and may be various.

6 is a flowchart showing a method of introducing a coolant according to an embodiment of the present invention. Hereinafter, a method of introducing a coolant according to an exemplary embodiment of the present invention will be described.

Coolant input method according to an embodiment of the present invention is a coolant input method that can input the coolant into the opening of the mold. Referring to FIG. 6, the method of introducing a coolant, a process of providing a coolant and a path part (S110), a process of placing the path part on the upper part of the mold (S120), and rolling the coolant along the slope of the path part to input the coolant into the opening of the mold It includes the process (S130).

Referring to FIGS. 1 to 5, first, a coolant input device 100 having a coolant 110 and a path portion 120 at least partially inclined downward may be provided. The opening size of the mold 30 may be different according to the type of cast produced in the mold 30. For example, the width of the opening of the mold 30 may vary from 1100 to 2200 mm. Accordingly, the length (or width) of the coolant 110 may be adjusted so that the opening of the mold 30 becomes smaller than the length (or width) to be extended.

The path part 120 may have a downward slope toward the opening of the mold 30. Therefore, when the coolant 110 formed in a cylindrical shape is placed on the path portion 120, the coolant 110 may roll along the path.

Then, the path part 120 may be positioned on the upper portion of the mold 30. That is, the path part 120 may be disposed on the long side plate of the mold 30. The slope of the path part 120 may be arranged to face the opening of the mold 30.

In addition, the path portion 120 can be aligned with respect to the opening of the mold 30. If the opening of the mold 30 and the position of the path part 120 do not match, the coolant 110 may not move to the opening of the mold 30 and may escape outside the opening. Accordingly, the path part 120 may be aligned with the position of the opening of the mold 30.

For example, the central portion of the path portion 120 may be positioned on the same line as the central portion of the opening of the mold 30. Therefore, it is possible to prevent the path member 123 provided in the path portion 120 from being located outside the opening of the mold 30. At this time, a groove through which the support member 121 of the path part 120 may be inserted may be formed on the upper surface of the mold 30. When the support member 121 is seated in the groove, the center of the opening of the mold 30 and the center of the path 120 may be positioned on the same line and disposed to face each other. The coolant 110 moving through the path part 120 may be stably guided into the opening of the mold 30.

Then, the coolant 110 may be positioned on the path part 120. The coolant 110 may be aligned with respect to the path portion 120. If the positions of the path part 120 and the coolant 110 do not match, the coolant 110 may deviate from the path formed by the path part 120 and cannot move to the opening of the mold 30 and may escape outside the opening. . Accordingly, the coolant 110 may be aligned with the location of the path portion 120 to be positioned on the path portion 120.

For example, the central portion of the coolant 110 may be located on the same line as the central portion of the path portion 120. Therefore, it is possible to prevent the coolant 110 from protruding outward of the path part 120. Accordingly, the coolant 110 may stably move without leaving the path portion 120.

In addition, since the coolant 110 is seated on the path part 120 as it can be rolled along a slope, the path of the coolant 110 moving to the blocking part 130 may be blocked. Accordingly, as shown in (a) of FIG. 2, the coolant 110 may be maintained in a stopped state on the path portion 120 by the blocking portion 130. Therefore, the operator can control the operation of the blocking unit 130 to adjust the timing at which the coolant 110 is introduced into the mold 30.

When the casting process enters at the end, it is possible to perform the operation of injecting the coolant 110 into the mold 30. When the blocking unit 130 controls the operation of the blocking unit 130 to open the path of the coolant 110, the coolant 110 may roll along the slope of the path unit 120. Thus, as shown in (b) of FIG. 2, the coolant 110 may move to the opening of the mold 30 and may be charged into the tail portion of the cast in the mold 30 to cool the unsolidified molten steel.

As such, the path portion 120 may safely inject the coolant 110 into the mold 30. Thus, when the coolant 110 is introduced, a safety accident such as an operator's burn due to the outflow of molten steel can be prevented. Therefore, the casting process can be safely performed, and the efficiency of the casting process can be improved.

In addition, the coolant 110 introduced into the cast steel can easily cool the tail portion of the cast steel to solidify the unsolidified molten steel. Accordingly, it is possible to prevent the molten steel from leaking due to the uncoagulated cast portion of the tail portion. Therefore, it is possible to safely protect the surrounding facilities and to stably perform the casting process.
