Analysis on the contact pressure between rolls of rolling mill

Contact pressure between rolls of wiling mill directly affects the on-load gap, roll wear and strength of the rolls. In this paper, a special element method called Green's function method is employed to investigate the effects of the factors such as strip width, roll diameter, bent force, roll crown and roll force on the contact pressure. Calculation results show good agreement with experiments, so it is useful for the roll crown, flatness control and the mill design.
