ROLLING METHOD AND ROLLING APPARATUS FOR FLAT-ROLLED METAL MATERIALS

摘要

A method and apparatus for stably producing a metallic plate material having no camber or an extremely slight camber. The method and apparatus use a rolling machine for a metallic plate material. The machine has at least work rollers and backup rollers. Force in the rolling direction acting on roll chocks on the work side of and the drive side of the work rollers is measure d. A difference in the force, in the rolling direction, between the work side a nd the drive side is calculated. Based on the difference, left and right asymmetrical components of roller opening of the rolling machine are regulat ed.
