ABSTRACT:
An elongation control system for controlling the elongation of a work to be rolled by a rolling mill applied to a continuous thin plate rolling equipment, through control of the rolling load of a press down device in the mill and control of tension on the work, i.e., control of the rates of feed of the work by feeders. The press-down device for pressing down a work roll is controlled based on the difference between the actual elongation detected by an elongation detector and a preset reference elongation. The rolling load at the moment the actual elongation accords with the reference elongation is held by a rolling load holding circuit, and the difference between the actual press-down position of the press down device corresponding to that press-down load and a target press-down position is outputted as rate correction signal to feed rate controllers for controlling the feed rates on the basis of the respective tensions on the work on the entrance side and the exit side of the rolling mill, whereby the feed rates are controlled and, therefore, the tensions on the work are controlled.
