摘要
Abstract
In order to optimize the production process of heavy plate steel ingot, the temperature fields in the steel ingot during unidirectional solidification under different hollow space mathematical model were numerically simulated by ProCAST software, the effect of hollow lateral wall distance on the solidification process of 45t large steel ingot was studied. The results show that the hollow lateral wall has significant insulating effect on the process of unidirectional solidification, and can inhibit heat transfer from lateral wall; when the thickness of hollow lateral wall is 4 mm, the effect of keeping temperature is best, the coagulation time extending, the quality of ingot plate improving.关键词
