摘要: 提出一个二维湍流模型模拟炼钢连铸过程中结晶器内的钢液流动及传热和凝固现象,并应用ANSYS软件求解流动和传热方程。通过对不同浇注速度的流场和温度场的计算,分析了浇注速度对铸坯质量的影响。为验证模型的正确性,将计算结果与宝山钢铁公司小方坯连铸生产数据进行比较,发现该模型可有效模拟连铸过程的钢液流动及传热和凝固现象。

Abstract: A two dimension turbulence model is presented to simulate the fluid flow and heat transfer in casting mould, and Ansys software applies to solve the equations. By means of simulating the flow fields and temperature fields of different inlet velocities, the relations betwen the inlet velocity and the quality of ingots are analyzed. Finally, the comparison between the predicted results and the measured data in BAO Steel is given,and shows that both are in good agreement.

Key words: the mould of continue casting, ANSYS, turbulence
