Abstract: A software that can be used to calculate the strip crown influencing ratio was developed by 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 backup 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 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.
