摘要

通过质量守恒方程、动量守恒方程和传热守恒方程的相互作用，对结晶器内钢液或熔体凝固点附近温度的数值计算进行了分析。用渐近方法分析了钢水通过模具壁抽热冷却的过程，得到了描述熔体-空气界面温度的常微分方程。同时，利用OpenFOAM软件对结晶器内熔体在凝固点附近的温度进行了数值计算。

A numerical evaluation of the temperature of a solidification point in ingot casting processes

An analysis for the numerical computing of the temperature around a solidification point of liquid steel or melt contained in a mould is performed via the interaction of the conservation equations of mass, momentum and heat transfer. A cooling process of liquid steel due to the extraction of heat through the walls of the mould is analyzed using asymptotic methods and an ordinary differential equation that describes the temperature of interface melt-air is obtained. Also, the temperature of the melt in the mould around the solidification point is computed numerically using the OpenFOAM software.
