Research on Generalized Overall Shape Setting Control Models with Asymmetric Shape Control Function for UCM Mill

Abstract:

Towards the insufficiency of the research on asymmetric shape defects control, and the equipment of new asymmetric shape control device—inverse symmetric roll bending for UCM cold mill, in this paper, by ANSYS finite element simulation, high-precision rolls-strip coupling models were established, and the difference of control character among all the symmetric and asymmetric shape control methods were analyzed, then generalized overall shape setting control models with asymmetric shape control function was proposed. It was proved by field application that the control models can effectively control asymmetric and high-order shape defects with the coordination of all the symmetric and asymmetric shape control methods. Consequently, expansive research and apply prospect should be expected.
