Improvement of Rolling Dynamics to Increase Roller Life in
· The downtime of ball-rolling mills is largely associated with the replacement of worn rollers. In the present work the degree and location of critical roller wear are studied the greatest wear is observed at the flanges in the billet-capture zone. The conditions required for billet capture and successful rolling are determined analytically.
