Production Procedure
Forged work roll features
1. Choose high strength forging material
2. Forging raw material choose ESR ingot
3. Long time annealing after forgings to remove inside stress
4. Oil quenching heat treatment to reduce crack risks
5. Double -frequency quenching to reach a high hardness value and depth layer
6. Hardness range: HRC55-65
