Study on setting method of flatness target curve of SUNDWIG 20-high mill considering target crown

The flatness target curve is important in the control theory. accuracy of an factor to determine load means and quality. Aiming at defect that crown each pass after rolling cannot be controlled quantitatively traditional formulation cold rolling, a new method considering was proposed. Specifically, can set by combining total proportional change hot field instability discrimination model field. incoming material finished product allocated pass, applied ensure stability plate. purpose quantitatively, so thickness plate meet production requirements. Taking SUNDWIG 20-high mill typical products as example, simulation results show that, on basis ensuring obtaining minimum available make requirements same time setting pass.
