The taper of the die body is 13.4%, and the height-diameter ratio of the die body is 1.45.
The diameter of the mold bottom water gap is 120-140 mm.
The die body is provided with a die body lifting lug, and the die bottom is provided with a die bottom lifting lug.
Adopt the utility model discloses, during the pouring, the molten steel gets into the mould body through the mould end mouth of a river, accomplishes the pouring when the molten steel reachs the heat-insulating shield.
The utility model has the advantages that: the internal quality of the steel ingot is effectively improved by increasing the taper of the ingot body of the steel ingot and controlling the height-diameter ratio, and the multi-edge ingot body can increase the cooling area when being solidified, thereby avoiding the tensile crack in the contraction process, improving the surface quality of the steel ingot and being particularly suitable for 38-47 tons of steel ingots.
