Description
Technical field
The utility model relates to the middle steel ladle of the firm usefulness of a kind of continuous casting, is specifically related to a kind of tundish punching groove that is inlaid in its molten steel impact zone.
Background technology
In pneumatic steelmaking, continuous casting production often is subjected to the tundish restriction in service life, and the molten steel impact zone of tundish, particularly its bottom are the easiest positions that is subjected to molten steel scouring and damages, in case tundish leakage accident very easily takes place the impact zone corrupted.The present steel plant of China continuous casting impact zone of tundish, generally adopt the mode build heat-insulating shield by laying bricks or stones or to apply magnesia liner coating to make up impact zone, not only difficulty of construction is big, cycle is long, and service life is also far below other position of tundish, cause the significant wastage of refractory material, cause the continuous casting cost high for a long time.
Summary of the invention
The purpose of this utility model is: overcome the tundish the deficiencies in the prior art, provide a kind of antiscour, anti-erosion, heat insulation, be not tied up with, pollution-free, repair the integral prefabricated tundish punching groove that bag time weak point, long service life, profile size are consistent with the tundish impact zone, embed the impact zone use.The technical solution of the utility model is: a kind of continuous casting tundish punching groove, integral prefabricated by profile, size, open top consistent with the tundish impact zone constitutes, comprise the punching groove housing, be positioned at a buffering water level mouth and a stream steel groove that has on the top of drawing the steel side wall drawing steel side wall middle part to have, the top of wall has the deslagging groove behind punching groove, it is characterized in that: 1. the bottom of this punching groove housing is provided with the shock resistance composite bed; The inside lock junction of 2. drawing steel side wall and both sides body of wall is for strengthening the angle.Additional technical feature is: the inside lock junction of 1. described slag blocking wall and both sides body of wall is provided with level and smooth fillet, the thickness of corner, 2. described reinforcement angle is greater than the thickness of both walls, 3. described anti-impacting layer adds the phosphate binders mixing by magnesium chrome refractory layer and constitutes, 4. described anti-impacting layer adds the phosphate binders mixing by the magnesia refractories layer and constitutes, 5. described anti-impacting layer adds the phosphate binders mixing by magnesium white clouds fire resistant materials layer and constitutes, and 6. described anti-impacting layer adds the resinoid bond mixing by the magnesia carbon refractory layer and constitutes.
Advantage of the present utility model is: because punching groove profile size is consistent with the tundish impact zone and be integral prefabricated, installation is simple, convenient, fast, again because the bottom of punching groove is provided with thicker anti-impacting layer, improved antiscour greatly, the synchronous life-span at anti-erosiveness and each position, also having solved in the past, coating turns over the difficult technical problem of bag, reduced the maintenance expense of tundish, saved the refractory material expense, alleviated working strength of workers, reduced production cost, made it to use the tundish of punching groove to draw the steel time, increased several times than common tundish, shorten the production cycle greatly, improved output of steel.
