摘　　要：针对唐山钢铁有限责任公司带钢厂的生产实际,借助理论与实验结果,研究了C-Mn钢热轧过程中各道次奥氏体的再结晶规律,计算结果与实测结果吻合较好,说明给出的组合模型用于窄带热轧的生产是可行的,它为在生产中控制与预报带钢的组织性能提供了奥氏体再结晶的定量化基础,并为再结晶软化不充分时的力能计算提供了修正依据。Based on the practice the recrystallization of C-Mn steel during narrow strip hot rolling was studied with modeling. The calculated results agreed well with measured, h shows that the model is feasible for production of narrow hot rolled strip. The result provides theoretical base for controlling and predicting the microstructure and mechanical properties of narrow strip and correcting rolling force and energy as required when the recrystal-lization softening is insufficient.
