Mill stands and roll chocks are cladded with vertical wear liners as guides and bearings for these mill components. Through sliding wear; impact loads and corrosion the contact areas of these liners are exposed to considerable wear. This leads to thickness reductions and thus to growing clearances between the mill housings and the chocks. The chocks are displaced in both the vertical and horizontal direction and tend to in' dine. At the same time, the area load acting on these liners rises considerably. The horizontal displacement, so called cross rolling, causes transverse axial forces that heavily act on the roll bearings and the chock locking. There are also detrimental effects for the rolling process and the rolling result, such as chatter marks, up and down turning and sweeping of the strip. Specially designed, highly wear-resistant precision compound steel liners substantially reduce the wear effect through their extremely hard and highly abrasion and corrosion resistant surface. The non-hardened base material features lower strength than the cast steel of the equipment. Thus precision compound steel liners do not only contribute to a distinct improvement of the rolling result but also to better rolling mill economy.
