Description

Work roll placing frame Technical Field The utility model relates to the technical field of work roll placing frames, in particular to a work roll placing frame. Background The hot rolling is an important process in the strip steel production flow of a modern steel mill, in the hot rolling production process, the roll changing operation of a rolling mill working roll is usually required to be stopped every time a batch of slabs are rolled, in the hot rolling strip steel production process, a finishing mill working roll is required to be frequently changed (3-4 times per shift), and the roll changing efficiency directly influences the production yield and the cost of a production line. The traditional work rolls are stored and transported and generally depend on a simple frame body, the work rolls are simply placed on the frame body without a fixing mechanism, roll body shaking and collision are easily caused by axial deviation during moving or taking and placing, roll surface scratch or journal deformation is caused, subsequent rolling precision is affected, meanwhile, manual auxiliary alignment and fixing are needed during taking and placing the work rolls, the work rolls are not matched with the high-efficiency requirements of a modern full-automatic roll changing system, non-production time is prolonged, and rolling line efficiency is restrained from being improved. In view of this, we propose a work roll stand. Disclosure of Invention The utility model aims to provide a work roll placing frame for solving the problems in the background technology.
