摘 要: 為了克服僅僅以鑄坯熱平衡為基礎(chǔ)進行建模的不足，針對傳熱、鋼水流動和凝固三種現(xiàn)象，建立起鑄坯凝固過程的數(shù)學(xué)模型。實驗表明，基于這種模型的計算機模擬結(jié)果與實際連鑄生產(chǎn)中的鑄坯凝固過程十分接近，為鑄坯冷卻控制提供了可靠的保證。

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
