Normalizing Open Die Forged Steel Parts Tempered Steel Mill Rollers Application

Normalizing and Tempered Open Die Forgings for Steel Mill Rollers are heavy-duty components manufactured through open die forging, followed by normalizing and tempering heat treatments. Designed specifically for steel mill rolling equipment, these forgings deliver uniform microstructure, dimensional stability, and exceptional resistance to thermal fatigue and mechanical stress in high-temperature rolling environments.

Key Attributes:

• Refined Internal Structure: Normalization optimizes the grain structure for consistent strength, while tempering enhances resilience and minimizes internal strains.
• Enhanced Resistance to Thermal Cycling Fatigue: Engineered to endure repeated heating and cooling cycles inherent in hot and cold rolling processes without developing fractures.
• Exceptional Resistance to Wear and Shape Distortion: Maintains precise dimensions even under extreme rolling forces and abrasive conditions.
• Consistent Mechanical Performance: Exhibits uniform hardness, strength, and flexibility throughout large-scale components.
• Minimized Internal Strains: The tempering process effectively reduces residual stresses, thereby extending operational lifespan under heavy loads.
• Adaptable Dimensions: Open die forging allows for the creation of rollers with diverse and substantial geometries, including backup and work rolls.

Principal Applications in Steel Production Facilities:

• Support Rollers (Backup Rolls): Essential structural rollers in multi-high rolling mills.
• Contact Rollers (Work Rolls): Rolls directly interacting with the material during hot or cold rolling of strips, plates, or sections.
• Intermediate Rollers: Employed in 6-high rolling mills to achieve precise thickness control.
• Roller Necks/Spindles: Critical, high-stress connection points between the rolls and the driving mechanisms.
• Roller Supports & Frames (Roll Chocks & Housings): Structural elements that provide support for the roll assemblies.
