Abstract

Mold casting has unique advantages in the production of complex shape, large single weight and small batch steel ingot. In the field of special steel, continuous casting still can not be replaced, but the quality problem of steel ingot is still the key bottleneck problem restricting the high-end of its products. At present, the industrial production often focuses on how to control the loose hole defects inside the ingot, generally ignoring the ingot surface and subcutaneous slag rolling problem. In view of this, with the study of 2,8 t octagonal ingot on the edge of arc, the influence of the nozzle brick structure in the average diameter of the nozzle is 40 mm and the cone of the nozzle is above 0,20.
