热型连铸工艺参数的数值分析

Numerical Analysis for Processing Parameters of Ohno Continuous Casting

根据热型连铸技术原理,建立了热型连铸凝固过程一维稳态温度场的物理、数学模型。通过数值计算,得出了铸型出口温度、冷却距离、拉铸速度和水的冷却强度等工艺参数对固液界面位置的影响。结果表明,该模型较为准确地反映了热型连铸的传热特点,铸型出口温度、冷却距离、拉铸速度和水的冷却强度对固液界面位置有明显影响。

Based on the principle of Ohno Continuous Casting (OCC) process, a physics-mathematical model of the steady temperature filed with one-dimensional heat transfer is established. The result of numerical analysis indicated that characteristic of heat transfer of OCC can be by rule and line reflected, model temperature, cooling distance, casting speed and cooling intensity have effects on the position of the liquid-solid interface. And those effects are important in processing of OCC.
