本文给出了钢 /铝液固相复合轧制中铝液凝固过程的二维数学模型及其近似解 ;利用等效比热法处理了凝固过程中的结晶潜热 ;给出了铝液初始温度、钢板预热温度和轧制速度等参数与复合板温度、凝固前沿的关系 ;预测了各参数的临界值 In this paper, the two-dimensional mathematical model and the approximate solution of the solidification process of molten aluminum in the liquid-solid phase composite rolling of steel and aluminum are given. The latent heat of crystallization in the solidification process is treated by the equivalent specific heat method. , Plate preheating temperature and rolling speed and other parameters and the temperature of the composite plate, solidification frontier; prediction of the critical value of each parameter
