Title: Method for controlling cold rolling of metallic belt
Inventor: MATSUI NORIYUKI
IPC: B21B37/18
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To keep rolling load constant and to prevent change in shape due to rapid load variation by executing load control for outputting a specific variation to a screw-down location when the rolling load is varied, and stopping the load control and returning to thickness control when the operation of reduction or release is executed by operators. SOLUTION: Variable variation ΔS* given by the equation (in the equation, Mc is a mill constant, Qc is a plastic constant, α is a tuning rate and ΔF is a load deviation.) is outputted to the screw-down location. By using this control in a state where inlet-side tension is not sufficiently applied, a metallic belt can be rolled without generating the rapid load variation. Consequently, the reduction of area, breakage, or the like caused by the load variation are prevented and it is useful for improving the working rate of rolling equipment. Moreover, by operating at such a speed as the operators can stop the equipment, the expansion of damage by an accident or the like is prevented but chance of breaking the belt is extremely low, so high-speed rolling is enabled and it is useful for improvement of working efficiency.  By changing a software simply, its effect is attained.
