摘要
建立了描述小方坯初始凝固的三维数学模型 ,并用实验数据进行了验证。计算表明 :三维模型比二维模型能更好的用来描述小方坯结晶器内的初始凝固和流体流动 。
A mathematical model depicting the initial solidification of the billet is built up and verified with the experimental data. Calculation shows that the 3-dimensional model can more effectively describe the solidification of the billet and flowing of the hot metal in the mould compared with the 2-dimensional model, and the return flow region in the mould is apparently reduced during solidification.
