Popis: In the rolling process, relative sliding happens due to the different velocities between the billet and work rolls. Quantitative evaluations of the relative sliding are essential to the failure analysis and damage prediction of rolls. The velocity and the distance of the relative sliding were evaluated with varying the billet size, the reduction ratio, the friction coefficient, the rolling temperature and speed, and compared between the flat and the caliber rolling. The relative sliding velocity and distance are increased with increasing the billet height, the reduction ratio and the rolling velocity. They are comparable between the flat and the caliber rolling at under-filling condition, and increased significantly in the caliber rolling at over-filling condition.
