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。 Through the heat transfer analysis and research on the solidification process of billet continuous casting, the mathematic model of solidification and heat transfer of billet continuous casting was established based on the actual equipment, production conditions and the continuous casting process of billet. The finite element method was used to solve the discretization, and the numerical simulation of the temperature field during the solidification of the slab was realized. The results provide reliable data for optimizing the process parameters and improving the quality of continuous casting of billet.
