COMPUTER-ASSISTED PROCESSING FOR ROLLING MILL FRAME RECONDITIONING

Abstract

Roll stands frames are the most important parts of a mill. This frame supports the work rolls and other devices or mechanisms that ensure lamination precision and mill productivity. The reaction forces created by metal deformation during rolling must be withstand by the frame. Therefore, when designing and executing mill frames, special attention must be paid to their mechanical properties, such as: stiffness and resistance. The roll stand frame must possess high stiffness, strength depending on the forces that will occur during rolling, but in the same time, the design must be simple and with minimal production costs. The aim of this paper is to present a computer-assisted design of a roll stand frame from a rolling mill used for cold rolling processes.
