FORGE-R-OD400*L2500
ETERNAL
Product Description
Forged work rolls are typically made of forged steel, which provides high toughness and purity, and are widely used in cold rolling, hot rolling, and other types of rolling operations.
Application
Forged crush rollers are used to crush all kinds of steel,tyre,mineral etc .
Crush roll raw material grade choice
42CrMo , H13 etc .
| 42CrMo | C | Si | Mn | Cr | Mo | P/S |
| 0.38-0.45% | 0.17-0.37% | 0.5-0.8% | 0.9-1.2% | 0.15-0.25% | ≤0.035% |
| H13 | C | Si | Mn | Cr | Mo | V | P/S |
| 0.32-0.45% | 0.8-1.2% | 0.2-0.5% | 4.75-5.5% | 1.1-1.75% | 0.8-1.2% | ≤0.03% |
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
