production of hot rolled strips in wide strip rolling mills. SUBSTANCE: method comprises steps of cooling up rolled piece along its whole thickness at each final pass; arranging cooling up zones symmetrically relative to strip axis alternatively relative to non-cooled metal zones; periodically shifting cooling up zones relative to roll barrel. EFFECT: possibility for making prestressed rolled sheets in rolling mill by process with enhanced operational parameters. 3 cl, 2 exp, 2 dwg
