Abstract
A continuous casting bakie impacting groove comprises a pre-cast product whose appearance, size and thickness are matched with that of the bakie impact zone, and whose top is open to ambient air, wherein the bottom thickness of the impacting groove is thicker than that of the side wall, the height of the steel side wall is matched with that of the other walls, and the corner connection parts of the side walls are strong angel or arc angle; the appearance of the impacting groove is matched with that of the bakie impact zone, and the cave appearance of the bakie impact zone is circular, rectangle or polygonal. The utility model has the advantages of good scour resistance and erosion resistance, non-pollution, short repair time, long life and convenient use.
Description
Technical field
The utility model relates to a kind of middle steel ladle of making steel the industry continuous casting steel, is specifically related to a kind of tundish punching groove that is inlaid in the tundish 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 to overcome the tundish the deficiencies in the prior art, a kind of antiscour, anti-erosion be provided, be not tied up with, pollution-free, repair bag time weak point, long service life, profile size and adapt, embed the integral prefabricated member that impact zone can use with the tundish impact zone.
The utility model is achieved through the following technical solutions:
Continuous casting tundish punching groove, the integral prefabricated member of, open top suitable by profile, size and thickness and tundish impact zone, punching groove housing bottom thickness is greater than the thickness of its peripheral side wall, it is characterized in that: draw the height of steel side wall and other position body of wall height suitable, the inside lock junction between the side wall is for strengthening angle or circular arc; The shape of the planar profile of described punching groove and tundish impact zone is suitable, and the inner chamber flat shape is circle or rectangle or polygon.
The planar profile of described punching groove is a rectangle.
The planar profile of described punching groove is trapezoidal.
The planar profile of described punching groove is a triangle.
The planar profile of described punching groove is circular.
The planar profile of described punching groove is a polygon.
Advantage of the present utility model is: because punching groove profile size adapts with the tundish impact zone and is integral prefabricated, installation is simple, convenient, fast, thicker owing to the bottom of punching groove again or establish impact resistant composite material layer, peripheral side wall is thin, improved antiscour greatly, anti-erosiveness, make the life-span at each position of tundish reach synchronous, reduced the maintenance expense of tundish, saved the refractory material expense, alleviate working strength of workers, reduced production cost, reduced the generation of leakage accident, use the tundish of punching groove to draw the steel time, increase several times than common tundish, shortened the production cycle greatly, improved output of steel.

Mark among the figure: 1 is the punching groove housing, 2 is the molten steel outlet that draws steel side direction bottom to have on the punching groove housing, 3,4 is the deslagging groove, 5 is the thick district of middle part epirelief of punching groove bottom land, and 6 is the recessed thin district of bottom land periphery, and 7 are the inside wall of upper thin and lower thick shape structure for punching groove, 8 is bottom land, 9 for drawing the steel side wall, and 10 is inside lock, and 11 is inner chamber.
The specific embodiment
Continuous casting tundish punching groove, by profile, size and thickness and tundish impact zone adapt, integral prefabricated of open top constitute, the bottom of this punching groove housing 1 than other position thick or employing and high-strength material make complex; The height that draws steel side wall 9 and the body of wall height at other position and shape change by the different of the planform of tundish and requirement, and its inside lock 10 junctions are adopted and strengthened angle or circular arc links to each other; The planar profile of punching groove is set as square, trapezoidal, triangle, circle or polygonal according to the operating position of tundish and tundish impact zone shape different, and the inner chamber flat shape can be designed to circle, rectangle or polygonal equally.Different according to user's tundish shape, capacity with other position structure, design the punching groove mould that adapts with it, can adopt magnesian, magnesium calcareous material, magnesium chromia material, magnalium material or corundum based refractory materials, allocate an amount of fortifying fibre into, make bond with phosphate, resin, refractory cement or oxide, add suitable quantity of water and stir into pug (except the resin-bonded), the mould of packing into is through vibration or ramming process, and the oven dry demoulding gets final product.Make integral prefabricated, setting-in is gone into the tundish impact zone and can be used.
Because punching groove profile size adapts with the tundish impact zone and is integral prefabricated, installation is simple, convenient, fast, thicker owing to the bottom of punching groove again or establish impact resistant composite material layer, peripheral side wall is thin, improved antiscour greatly, anti-erosiveness, make the life-span at each position of tundish reach synchronous, reduced the maintenance expense of tundish, saved the refractory material expense, alleviate working strength of workers, reduced production cost, reduced the generation of leakage accident, use the tundish of punching groove to draw the steel time, increase several times than common tundish, shortened the production cycle greatly, improved output of steel.
