Description

Novel continuous casting pouring flow baffle

Technical Field

The utility model relates to a novel continuous casting flow baffle of opening water.

Background

At present, a combined trial crystallizer is used for slab continuous casting, and is formed by combining four copper plates, so that corner gaps are inevitable, slag is fed into the gaps if the tightening pressure is insufficient, the corner gaps are larger and larger if the gap is not cleaned in time, cold steel is fed into the joints in the casting process (particularly during casting or tundish replacement) easily due to the existence of the gaps, the casting blank corners are scratched if the result is light, and the steel leakage accident due to hanging is possibly caused if the result is heavy. The current control measures are as follows: 1. controlling the quality of the crystallizer, checking corner gaps before casting, preventing the crystallizer from being started up when the standard corner gaps exceed the standard, and coating daub in the corner gaps before casting for the first furnace according to the standard corner gaps of less than or equal to 0.3mm, wherein the gaps are reduced by 2, and casting stop flow wood plates are used to prevent casting molten steel from splashing and entering the joints to clamp steel. However, the current flow-blocking wood boards have certain defects. The flow blocking board is purely deficient: 1. the current flow blocking boards are all plane boards with the length of 500mm and the thickness of more than 10mm, the width of the crystallizer is generally smaller than the thickness of the crystallizer for being convenient to take out, corner gap parts cannot be completely shielded, production cost is increased, 2 the flow blocking boards in the form of boards are easy to burn or easy to cause slight explosion due to humidity, and 3, the flow blocking boards are inconvenient to use when being poured in a ladle in a quick replacement process.

Disclosure of Invention

The utility model provides a novel continuous casting flow baffle which can prevent splashing and can be melted with molten steel together and is convenient to use.

The utility model discloses a concrete technical scheme, a novel opening of continuous casting waters and keeps off and flows board, the package rubbing board body, this plate body are buckled and are the notch font form that the suitable for reading is big, the end opening is little, the plate body comprises thickness 0.5 mm's sheet iron, notch font cell body suitable for reading length, wide all be 250mm at least, notch font cell body end opening length, wide all are not greater than 220mm, the perpendicular length of notch font cell body is 400mm, the upper end back of notch font cell body is turning over outwards and is being turned over and is being set up a protruding tongue.

The utility model is a groove body matched with the thickness of the crystallizer, and the groove body can be inserted into the two sides of the seam of the two sides of the crystallizer before casting. The utility model discloses practice practical demonstration: the flow baffle plate with the structure and the material achieves the expected purpose, and has the advantages that: 1. the crystallizer is made of iron sheet with thickness less than or equal to 0.5mm, is trapezoidal in shape, and only needs to be inserted into each of two sides of the crystallizer before casting, so that the crystallizer is practical and convenient, and the cost can be saved. 2. The iron sheet is thin and has certain deformability, the size of the trapezoid opening is slightly larger than the thickness of the crystallizer, four corner gaps can be completely protected after the iron sheet is inserted, 3, the baffle plate can be directly pushed into the crystallizer after casting start due to the fact that the manufacturing material and molten steel are the same, the baffle plate does not need to be forcibly picked out, the operation is simple, 4, the iron sheet and the molten steel are naturally integrated with each other along with the rising of the molten steel level of the crystallizer, extra attention is not needed, and 5, the iron sheet can be used at any time when a tundish is replaced. The utility model discloses can effectual control open the emergence of the bleed-out accident and the casting blank quality accident that the corner portion pressed from both sides the steel and cause after the input.

Detailed Description

The utility model provides a novel continuous casting that opens and waters fender stream board, as shown in figure 1, figure 2, the package rubbing board body, this plate body are buckled and are the shape of notch font cell body 1 that the mouth is big, the end opening is little, the plate body comprises thickness 0.5 mm's sheet iron, 1 mouth length, width on the shape of notch font cell body all be 250mm at least, 1 end opening length, the width of the shape of notch font cell body are all not more than 220mm, the vertical length of the shape of notch font cell body 1 is 400mm, the upper end back of the shape of notch font cell body 1 is turning over outwards and is being turned over and is being set up a protruding. When the tongue-shaped groove is used, the two groove bodies 1 in the shape of the Chinese character 'ao' are placed into the two side edges of the crystallizer 3 face to face, and the convex tongues 2 are abutted to the two side edges of the crystallizer 3.

Claims (1)

1. The utility model provides a novel continuous casting that opens waters fender stream board, includes the plate body, characterized by: the plate body is bent to be in a concave groove shape with a large upper opening and a small lower opening, the plate body is made of sheet iron with the thickness of 0.5mm, the length and the width of the upper opening of the concave groove body are at least 250mm, the length and the width of the lower opening of the concave groove body are not more than 220mm, the vertical length of the concave groove body is 400mm, and a convex tongue is arranged on the back of the upper end of the concave groove body in a way of being turned outwards.
