| 摘 要： | 利用有限元法研究了连续铸挤工艺中液态金属的动态凝固过程 ，数值计算和实测结果表明，摩擦热和变形热对铝材连续铸挤凝固区的温度场有较大影响，采用等价比热法处理凝固潜热问题是切实可行的，通过速度场与温度场的耦合计算，得到了凝固区的温度场分布情况。

| Abstract: | The solidification process of liquid metal in the CASTEX technique was studied by FEM(finite element method). The calculated and experimental results show that friction heat and deformation heat have great influence on the distribution of temperature and it is feasible to handle the latent heat of solidification process by equivalent specific heat method. The distribution of the temperature field in solidification zone was gained by coupling calculating of velocity field and temperature field. |
