采用自行开发的计算固相板坯二维温度场有限元程序SLBT及ANSYS大型有限元程序分别求解了固相板坯空冷过程的温度场 ,并将两种计算结果进行了比较·可以看出 ,两种计算结果接近 ,同时为了检验计算精度 ,将计算值同时与实测值进行比较 ,计算结果与实测值吻合·分析结果对于连铸连轧技术的应用提供了理论基础并具有实际指导意义· The temperature field of air-cooling process of solid-phase slab was solved by using the finite element program SLBT and ANSYS which were developed by ourselves to calculate the two-dimensional temperature field of solid slab, and the two results were compared. In the meantime, in order to test the calculation accuracy, the calculated value is also compared with the measured value at the same time. The calculation result is in good agreement with the measured value. The analysis results provide a theoretical basis and practical guidance for the application of continuous casting and rolling technology.
