建立了铸坯凝固传热数学模型,模拟计算了铸坯温度场、坯壳厚度、热流场、坯壳热收缩应力场、坯壳与铜壁间气隙厚度;计算坯壳厚度与实测坯壳厚度基本吻合;计算结果为连铸机生产、连铸机设计提供参考。
The mathematic model of slab solidification and heat transfer was established. The temperature field, shell thickness, heat flow field, thermal shrinkage stress field and the air gap thickness between shell and copper wall were calculated. The thickness of the shell is basically the same. The calculation results provide reference for continuous casting machine design and continuous casting machine design.
