  • Control Of Metal Rolling (AREA)

Abstract

PURPOSE: To make constant the rolling load of the lowest stand, and to manufacture the steel sheet provided with specified average sheet gauge and specified sheet crown, by carrying out the gauge control depending on the gaugemeter system with the automatic controller, in the pass or stand just before the final finishing.
CONSTITUTION: In the continuous rolling mill provided with six stands, etc., the sheet gauge control is carried out by the automatic controller D depending on the measurements being sent every moment from the rolling load detector B5 and the screw position detector C5 installed in the fifth stand A5. Hereby, the gauge of steel sheet entering into the lowest stand A6 varies so as to cancel the temperature fluctuation to cause the variation of deformation resistance; and the rolling reduction is carried out in the lowest stand A6 under a condition of constant rolling load. As a result, the control is so carried out as to make constant the lateral distribution of the sheet gauge.
