摘　　要：通过对方坯连铸凝固过程的传热分析和研究,结合攀钢实际设备、生产情况及方坯连铸工艺,建立了方坯连铸凝固传热数学模型。采用有限元法进行离散化求解,实现了整个铸坯在凝固过程中温度场变化的数值仿真模拟,为优化工艺参数以提高方坯连铸质量提供了可靠的数据支持。A mathematical model of solidification and heat transfer for continuous casting square billet was established according to the analysis and research by equipments, situation of production, continuous casting technology on square billet of ANSTEEL. The finite element method was used to discrete solution. The numerical simulation of temperature field change was realized in solidification process of the whole billet. It can provide reliable and digital support for optimization of process parameters and improvement of continuous casting billet quality.
