所以，开发连铸坯凝固传热与应力分析耦合模型是非常必要的。
So it is necessary to develop the coupled model of heat transfer and stress for continuous casting billet.
针对残余应力的计算，结合铸造中落砂工艺，对落砂前后不同的传热模型进行了相应的调整。
In order to calculate residual stress in the casting, different heat transmission models before and after shake out had been established.
应用模型分析了大方坯连铸结晶器内的传热过程和坯壳的应力分布。
The heat transfer in the mold and stress distribution in the bloom at different casting speeds were obtained by using the model.
