摘　　要：针对750mm×450mm×120mm异形坯,使用有限元软件建立了铸坯在结晶器内的传热、凝固、收缩及异形坯结晶器铜板热力耦合分析模型。在分析拉速对铸坯收缩、结晶器铜板温度及其变形的影响的基础上,确定了异形坯结晶器铜板的参考锥度,为异形坯结晶器的设计提供参考。Aiming at large beam blank with size of 750 mm × 450 mm × 120 mm,the ANSYS software was used to establish the heat transfer,solidification and shrinkage model in the mold of the beam blank and the thermo-mechanical coupling model of the mould copper plate.Influence of casting speed on the contraction of beam blank,temperature and deformation of the copper plate was analyzed to determine the reference taper of the copper plate,which provides a basis for the mould taper design of beam blank.
