摘　　要：采用影响函数法开发了带钢凸度影响率计算软件 ,研究了支撑辊凸度、工作辊弯辊和单位宽度轧制力对带钢凸度的影响规律 ,得出了大凸度支撑辊四辊轧机支撑辊凸度影响率、工作辊弯辊影响率和单位宽度轧制力影响率的 5次多项式拟合系数 ,分析了CVC工作辊改为平辊横移、采用大凸度支撑辊辊系的带钢凸度控制能力 ,为宝山钢铁股份有限公司 2 0 5 0热轧厂F6 ,F7机架辊系变更和板形控制模型参数调优提供了理论依据·A software that can be used to calculate the strip crown influencing ratio was developed by employment of the G-function method. The effective law was studied on the factors such as back-up roll crown, the work roll bending and the specific force acted on the strip crown. The quinary order fit coefficient was derived on the back-up roll, the work roll bending and the specific force influencing ratio on the high mill. The control capability was analyzed for the both convention roll method and the NBCM ( New Backup Roll Crowning Method ). The optimal model parameters are presented theoretically when the roll shape is changed on the No.6 and No.7 stands.
