摘 要: 为了克服仅仅以铸坯热平衡为基础进行建模的不足,针对传热、钢水流动和凝固三种现象,建立起铸坯凝固过程的数学模型。实验表明,基于这种模型的计算机模拟结果与实际连铸生产中的铸坯凝固过程十分接近,为铸坯冷却控制提供了可靠的保证。

Abstract:A casting blank solidification model was presented in which both thermal transference and liquid steel flow dynamics in the solidifying blank were considered. This model overcomes the drawbacks of modeling based only on conduction of thermal energy. The simulation results and measurements of experiments in the casting line coincide well with each other.
Key words: casting blank thermal transference convection solidification modeling
