摘要： 为研究连铸过程中拉速及过热度对凝固传热的影响，采用商业有限元软件ANSYS，对316不锈钢板坯厚度生长情况进行了模拟. 采用2-D模型，分别计算了拉速为0.4, 0.5, 0.6 m/min及过热度为30, 40, 50℃时坯壳出口温度、坯壳厚度及表面温度的变化，探讨了坯壳生长及厚度变化规律. 结果表明，拉速从0.4~0.6 m/min变化，坯壳出口温度升高83℃、坯壳的出口厚度平均减薄3.2 mm、表面温度随拉速提高而升高；过热度从30~50℃变化，坯壳出口温度升高20℃、表面温度平均升高20℃、坯壳的出口厚度平均减薄1.35 mm.

Abstract: In order to study the influences of casting speed and superheat on solidification and heat transfer in the continuous casting process, the growing process of 316 stainless slab thickness was simulated by finite element software ANSYS. Using two-dimensional model, the changes of slab shell outlet temperature, slab shell thickness and slab surface temperature were calculated when casting speed was 0.4, 0.5, 0.6 m/min and superheat 30, 40, 50℃ respectively. Meanwhile, the rules of slab shell growth and thickness change were discussed. The results showed that the outlet temperature rised by 83℃, average value of outlet thickness decreased 3.2 mm and surface temperature rised when casting speed changed from 0.4 to 0.6 m/min, and outlet temperature rised by 20℃, average value of outlet thickness decreased 1.35 mm and surface temperature rised by 20℃ when superheat increased from 30 to 50℃.
