Intelligent Manufacturing Control Strategy and Application Verification of Support Rolls in Hot Tandem Rolling
Hot rolling is one of the main processes of sheet metal forming control in intelligent manufacturing.In order to improve the control precision of 2 500 mm hot strip rolling,an optimal control method of channeling roll in hot strip rolling based on the contact pressure between rollers was designed.The wear state of the actual work roll is analyzed by setting the production line and the application is verified on the contact pressure forging equipment between rollers.The results show that the new roll shape has greater lateral stiffness than the old roll shape,and the new roll shape can enhance the anti-interference effect of the rolling mill.Application verification shows that the proposed control can reduce the peak wear value,improve the uniformity of wear state,reduce the wear amount of work rolls,and increase the rolling length.
