Abstract

This paper provides an analysis of the 42CrMo round billet by the vertical caster. Based on ZhongYuan Special Steel continuous casting process parameters and CAFE nucleation parameters, the ProCAST chip-moving boundary method is adopted to conduct the numerical simulation of round billet. Simulation and practical cases both have the same macrostructure morphology, the round billet has the center equiaxial crystal of 41,2 %. As the superheat of liquid steel and cooling intensity is reduced, the average radius of crystal decreased, the number of crystal increased, and the macrostructure showed a trend of progressive elaboration.

Keywords
