Abstract

PURPOSE:To roll a strip of uniform shape, by catching the change of reduction- cylinder position transiently and, controlling signals of load cells to enable a stable threading. CONSTITUTION:Rolling loads are converted into electric signals by load cells 7, 7', and the signals are sent to a circuit B wherein the loads are added and amplified; an electric signal amplified the load difference between the operation side and the driving side is sent to a circuit C wherein the loads and positions are added. On the other hand, respective positions of reduction cylinders 5, 5' are sent to a circuit A wherein cylinder positions are added and amplified by cylinder-position detecting devices 6, 6'. Here, the cylinder-position difference between the operation side and the driving side is obtained, and an electric signal multiplied a specific factor to said difference is sent to a circuit C. A modified quantity obtained by removing harmful components in this signal is sent to servo valves 12, 12' for the cylinder driving through a PID controller 11; further, signals from the valves 12, 12' are fed back to screw-down devices 13, 13' so as to control the rolling reduction.
