Abstract

PURPOSE:To make possible the great edging, and to reduce the amount of sheared crop, by pressing the longitudinal end zones of the slab with the flat anvils from both sides over a specified contact length, at pressing the slab from both sides by the side press equipped with the flat anvils. CONSTITUTION:At pressing the slab in the direction of breadth by the flat anvils equipped with the side presses P which have a large acting stroke and are arranged in front of the roughing mill R on both transverse sides of the rolling line, if the pressing by the flat anvils is given to the longitudinal end zones of the slab over a contact length equivalent to 0.35-0.8 times of the initial breadth of the slab before the edging work, the amount of the sheared crop accompanied by the edging as great as about 300mm can be remarkably reduced.
