Abstract

PURPOSE:To considerably save heat energy by heating a stainless steel strip passed through the final pass of a hot rolling equipment to a specified temp. and cooling it at a specified rate. CONSTITUTION:A stainless steel strip 2 passed through a hot finish rolling mill 1 as the final pass of a hot rolling equipment is reheated with a heating furnace 3 to 1,010-1,150 deg.C necessary for the solubilizing heat treatment for performing the softening and the solid soln. treatment of grain boundary deposits such as carbon, and it is rapidly cooled to 500 deg.C in >=15 sec with a cooling apparatus 4. The cooled strip is then passed through a solid soln. treatment vessel 5 for removing a produced oxide film, and it is coiled. Thus, a stainless steel sheet 2 subjected to solubilizing heat treatment and solid soln. treatment in succession after hot rolling is manufactured.
