Heavy plate work rolls are mainly used for straightening heavy plate strips. In general, the straightening force of the heavy plate leveler is high, the shape of the incoming material is also poor, there is a lot of oxidation, and the roll surface is easily worn and sticky. Generally, the heavy plate leveler is equipped with a bending roll device, which requires special alloying elements in the selection of raw work roll material to ensure that the roll body is "hard outside and tough inside".
Heavy plate work roll is an important part of theheavy plate leveling machine. During the straightening process, the plate of work roll contacts with the plate directly, causing the plastic deformation of the plate. High pressure working conditions, and the quality problems existing of the plate itself, it is easy to cause the leveling roll crack, peeling, fracture and other failures. Therefore, choosing an appropriate remanufacturing method of the leveling roll can not only prolong the service life of the leveling roll, but also improve the straightening effect of the strip.
