实例计算了在三种拉坯速度下凝壳热变形和鼓肚变形。
Then the practical example is given to calculate the thermal deformation and the bulging deformation of the solidified shell under three tension speeds.
结合水模型试验分析了浇铸通道内压力、拉坯速度和间隙三者之间的关系。
The links among the pressure, the casting speed and the gap in the casting passage have been analyzed with the hydraulic modelling test.
因此可根据坯壳厚度合理地确定冷却强度及拉坯速度或由冷却强度预测坯壳厚度。
Therefore, the cooling intensity and the casting speed can be rationally determined by the thickness of strand shell.
