<p><P>PROBLEM TO BE SOLVED: To reduce the amount of edge seams and improve an yield of a product by controlling the width of a rolling stock, especially a rolling stock made of stainless steel or ultralow carbon steel producing edge seams in hot rolling. <P>SOLUTION: Variations of the width of the rolling stock in a longitudinal direction are measured by a width gauge disposed in the outlet side of a roughing mill set one step before. Following the measured variation, width rolling reduction is conducted by a preset amount of width rolling reduction, in the whole longitudinal direction, with edgers attached to each of the roughing mills. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
