METHOD AND APPARATUS FOR ROLLING METALLIC PLATE MATERIAL

Title:

METHOD AND APPARATUS FOR ROLLING METALLIC PLATE MATERIAL

Document Type and Number:

WIPO Patent Application WO/2004/082860

Kind Code:

A1

Abstract:

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 measured. A difference in the force, in the rolling direction, between the work side and the drive side is calculated. Based on the difference, left and right asymmetrical components of roller opening of the rolling machine are regulated.
