Abstract

PURPOSE:To elimnate fluctuation of plate width and to improve yield in a hot reversing mill by measuring width after horizontal rolling and adjusting the amount of edging of vertical rolling. CONSTITUTION:The plate width of a rolled stock 1 after horizontal rolling at a pass is actually measured, and controlling is made to eliminate fluctuation of width due to flaw, that is an element that is not related to temperature at (m+2)th pass vertical rolling. Then, the width after horizontal rolling at (m+2)th pass is measured and controlling is made to eliminate fluctuation of width due to skid mark, that is an element related to temperature at (m+4)th pass. Controlling may be made at any pass that goes through vertical rolling and horizotal rolling and not limited to above-mentioned pass. Actual measurement may be made in the inlet side of the vertical rolling mill at (m+1)th pass and (m+3)th pass instead of outlet side of the horizontal rolling mill at (m)th pass and (m+2)th pass.
