Study on Unidirectional Solidification Ingot with Hollow Lateral Wall Insulation

G. W. Ao, M. G. Shen, Z. S. Zhang, B. L. Li: College of Materials and Metallurgy, University of Science and Technology Liaoning, Anshan City, China Hollow side wall insulation mathematical model of unidirectional solidification temperature field was carried out. With the aid of finite element analysis software ProCAST, directionally solidified ingot temperature field with hollow lateral wall insulation during the process of unidirectional solidification was simulated. The results show that the numerical simulation results are in good agreement with experimental results. The hollow side wall significantly improves the thermal insulation effect, inhibits heat transfer directionally solidified casting side wall, and reduces the lateral heat of the ingot. As the hollow side wall was used in nuclear power, large-scale steel and other special steel ingot improve the yield and quality, provide the basis of theory and application.
