摘要： 采用有限元差分法对连铸连轧生产过程的带钢温度场进行模拟.计算中考虑了辐射、对流换热、轧制时与轧辊之间的热传导以及变形热和摩擦热.结果表明,输送辊对带钢温度场的影响相对较小,大约使钢体温度下降14~18℃;精轧前的过程上下表面温差比较大,能达到20~25℃;考虑了输送辊影响的温度场与实测值更相近,符合实际.

Abstract: Finite difference method was used to simulate the temperature field of work piece during thin slab continuous rolling (TSCR). The model incorporated the effects of radiation, heat convection and heat conduction between rolls and work piece, as well as the heat due to deformation and friction of work piece is comparatively small. It was shown that the thermal effect of roll gang on the temperature field drop about 14-18°C. However, the temperature difference between the top and bottom of work piece is great in the process before finish rolling, up to 20-25°C. The predicted values from the model taking the effect of roll gang into consideration are close to the measured values.
