A common structure in hot strip mill backup roll bearings is to attach the conical sleeve of the slide bearing to the mill's shaft by a key. The key groove, cut to the conical sleeve, locally decreases the strength of the structure, causing deflections when load is exerted to it. These deflections are observed as rolling force variations, falling into sync with the backup roll rotation. In this research, we developed a new method to minimize force variations, based on 3D grinding of the mill rolls. We prepared four finite element models describing the backup roll bearings, and used those to determine the shape and magnitude of the deflection, which occurs during the roll's revolution. Using these models, we constructed the compensatio...
