摘　　要：探讨了铸轧过程强耦合的温度场与轧制压力建模。利用该模型对常规铸轧过程进行仿真计算,计算结果与实测值相吻合,从而验证了模型的正确性。在此基础上研究了超薄快速铸轧条件下铸轧速度、铸轧区长度、铸坯厚度等工艺参数对铸坯表面温度、轧制压力及摩擦应力的影响。Modelling of the strong-coupled temperature and draught pressure during roll-casting process is discussed. The validity of the models is verified by the good agreements of the calculating results with these tested. Based on this fact, the influence of technical parameters such as roll-casting speed, tip setback and strip thickness on surface temperature of strip, rolling pressure and friction stress is investigated.
