Abstract: The decoupling of complex interactions between work roll shifting and work roll bending is very important in achieving optimum strip flatness control of CVC mills. An analytically decoupled model that can explicitly describe the functions of work roll shifting and bending has been developed through analysis of the roll gap profile. The model can be used for flatness on-line control of 4-h CVC cold rolling mills.
