This is to carry out uniform scafing operation, especially, makes to be arranged at the side processing unit of described slab M
The center of 30 and the center of described slab M side are consistent, and carry out scafing operation, thus can improve for required institute
State the reliability of the scafing operation of the corner angle M3 of slab.
Here, described base frame 11 is to connect the basic dress of described first connection member the 12, second connection member 13
Put a part for main body 10.
That is, described base frame 11 can by be connected with upper and lower air cylinders Ay and with described first connection member 12 or second even
Relay part 13 connects.This is to drive upper and lower air cylinders so that tie with described first connection member 12 or the second connection member 13
The top and bottom processing unit 20 and the side processing unit 30 that close move to the thickness direction of described slab M.
Further, upper component 21a of described first connection member 12 and described top and bottom processing unit 20 and described side
First side members 31a of processing unit 30 combines, and described upper component 21a is above relative with described slab M's, and described first
Side members 31a relative with the one side of described slab M thus can by upper and lower air cylinders Ay make with described slab M above relatively
Any one the top and bottom processing unit 20 arranged and any one the side processing unit being oppositely arranged with the one side of described slab M
30 move to the thickness direction of described slab M, or can be moved to the width of described slab M by left and right cylinder Ax.
Further, lower member 21b of described second connection member 13 and described top and bottom processing unit 20 and described side
Second side members 31b of processing unit 30 combines, and described lower member 21b is relative with below described slab M, and described second
Side members 31b is relative with the another side of described slab M, thus can by upper and lower air cylinders Ay make with described slab M below
At another side that another top and bottom processing unit 20 of being oppositely arranged and the another side with described slab M are oppositely arranged
Reason unit 30 moves to the thickness direction of described slab M, or can be moved to the width of described slab M by left and right cylinder Ax
Dynamic.
As it has been described above, make to process list with the described top and bottom that described first connection member 12 or the second connection member 13 are combined
Unit 20 and side processing unit 30 are from the described upper therapeutic method to keep the adverse QI flowing downwards to the driving force that thickness direction or the width of described slab M move
Cylinder Ay and described left and right cylinder Ax passes over.
Here, described upper and lower air cylinders Ay is combined with described base frame 11, described first connection member 12 or second is made to connect
Relay part 13 moves to the thickness direction of described slab M so that with described first connection member 12 or the second connection member 13
In conjunction with described top and bottom processing unit 20 and described side processing unit 30 move to the thickness direction of described slab M.
Further, described left and right cylinder Ax is combined, to institute with described first connection member 12 or described second connection member 13
The one end of the width extension stating slab M is combined with described top and bottom processing unit 20 or described side processing unit 30,
So that described top and bottom processing unit 20 or described side processing unit 30 moves to the width of described slab M.
Described top and bottom processing unit 20 plays the effect that the top and bottom M1 of described slab can implement scafing, except this
Outside, it is also possible to concentrate injection oxygen to the corner angle M3 of described slab, so that the corner angle M3 of described slab carried out scafing
Operation.
To this end, described top and bottom processing unit 20 can possess top and bottom parts 21, top and bottom medium pore 22, edge, top and bottom
Hole 23.
That is, the described top and bottom processing unit 20 of the scafing device of one embodiment of the present of invention comprises the steps that up and down
Face component 21, is combined with top or the bottom of described apparatus main body 10；Top and bottom medium pore 22, is formed at described top and bottom parts
The central part of 21；And top and bottom edge hole 23, it is positioned at the both ends of described top and bottom parts 21, and the size in hole is along outside
Direction becomes larger, and expulsion pressure is higher than the oxygen of described top and bottom medium pore 22.
Here, described top and bottom parts 21 are and upper component 21a being oppositely arranged above of described slab M and with described
The general designation of lower member 21b being oppositely arranged below slab M.
Further, described top and bottom parts 21 play the institute forming described top and bottom medium pore 22, top and bottom edge hole 23 etc.
State the effect of the main body of top and bottom processing unit 20.

Connect from the oxygen storage tank O2 of the oxygen pressure of described flanking central hole 32 injection, and expulsion pressure is higher than from described side
The oxygen of the oxygen pressure of central aperture 32 injection, carries out scafing with the corner angle M3 to described slab.
As it has been described above, when described side face edge marginal pore 33 is to the oxygen of the corner angle M3 part injection high pressure of described slab, meeting
Produce the middle body than described slab M the hottest, more scafing phenomenon occurs therewith, therefore can also be to described
The corner angle M3 of slab carries out scafing operation.
However, it is possible to be connected with the oxygen storage tank O2 of this high pressure, the corner angle M3 of described slab is carried out scafing
Operation, it is also possible to described side face edge marginal pore 33 is shaped to specific shape, is carried out with the corner angle M3 to described slab
Scafing operation.To this, hereinafter will be described in detail with reference to Fig. 2 and Fig. 3.
Further, with the described top and bottom processing unit 20 shown in Fig. 4 and Fig. 5 similarly, described side processing unit 30
Described flanking central hole 32 may be formed at described relative the inclining of slab M with described side members 31 with described side face edge marginal pore 33
On inclined-plane.Thus, it is possible to make the oxygen to described slab M injection, fuel etc. carry out scafing to collide with described slab M
The mode not collided with described side members 31 flows.
On the other hand, the table to described slab M by described top and bottom processing unit 20 and described side processing unit 30
Face and corner angle implement the result of scafing operation as shown in Figure 8.
Here, the section of the slab M as shown in Fig. 8 (a) is only the two sides M2 of slab to be implemented scafing operation
Result.The result of oxygen is sprayed in i.e., the only flanking central hole 32 from described side processing unit 30.
Further, the section of the slab M as shown in Fig. 8 (b) be only the two sides M2 of slab is implemented scafing operation and
Only corner angle M3 is implemented the result of scafing operation.I.e., only from flanking central hole 32 and the side of described side processing unit 30
Face edge hole 33 sprays oxygen, or only processes single from the flanking central hole 32 of described side processing unit 30 and described top and bottom
