Abstract

A rolling mill comprising a pair of working rollers between which sheet metal is rolled; sensor means arranged to detect the contour of the laminated sheet in a plurality of sheet width zones; cooling means arranged to individually cool the rollers in a plurality of roller width zones, the zones being cooled at a particular time being designated as "connected" zones, and the zones not being refrigerated being designated as "disconnected" zones ; and control means sensitive to the outputs of the sensing means to identify the extreme "connected" zone that produces sheet metal that is closest in contour to the sheet metal produced by the "disconnected" areas, and the extreme "disconnected" area that produces sheet metal that is closer in contour to the sheet produced by the "connected" areas, thereby allowing switching control of the cooling means to be carried out accordingly.
