摘　　要：基于SPHC钢在H2结晶器内的凝固过程,利用有限元软件ANSYS中的单元生死技术,通过改变薄板坯单元的状态建立其在结晶器内随时间变化的二维非稳态模型。模拟出薄板坯在结晶器不同部位处的温度场及应力场分布情况,其结果可为优化结晶器锥度及改善薄板坯质量提供理论依据和技术基础。Based on the solidification process of SPHC steel in H2 mold,using element birth and death in ANSYS software which alters states of thin slab elements along with residence time in continuous casting mold,to simulate the thermal and mechanical states in 2D transient mode.Temperature and stress distributions of thin slab in different parts of H2 mold were obtained.This analytical work can provide theoretical bases for optimizing mold tape and improve the quality of product.
