METHOD OF PREVENTING ROLLING TROUBLE IN CONTINUOUS COLD TANDEM ROLLING MILL

摘要

PURPOSE:To improve the working efficiency and to stabilize the operation by comparing the distance between previously punched holes on a steel strip detected by a hole detector installed in a prescribed position in front of a rolling mill with a previously provided criterion value. CONSTITUTION:Holes of a size being harmless to rolling works are previously punched at changing points of manufacturing command and specification in the central part in the sheet width direction. A hole detector 6 detects a hole and inputs a detection signal to a control computer 2; the signal is compared with a previously inputted steel strip length and a decision is made whether the point is a changing point in accordance with a difference between the signal and the length. In this method, the working efficiency is improved.
