合理的控制影响铸坯质量的鼓肚量,有利于铸坯质量的提高。根据板坯实际生产,利用有限元法模拟凝固过程并建立二维热机耦合鼓肚模型,分析了拉速与二冷引起的蠕变时间、坯壳厚度及铸坯温度的变化对鼓肚的影响,为实际生产提供参考。
Reasonable control affect the quality of slab bulging, is conducive to improving the quality of slab. According to the actual production of the slab, the solidification process was simulated by the finite element method and the two-dimensional thermo-mechanical coupled drum belly model was established. The effects of the pulling speed and the secondary cooling on the creep time, the thickness of the shell and the temperature of the slab were analyzed. , For the actual production of reference.
