Large Diameter Rough Machined Heavy Steel Forgings for Rolling Mill Components. Our large diameter rough machined heavy steel forgings are engineered to meet the demanding needs of rolling mill systems. These components are designed to withstand extreme mechanical stress, repeated thermal cycling, and high torque during continuous operation. Forged from high-strength alloy steels and processed with precision open die techniques, they ensure superior structural integrity and service life.

Key Features:

• Large Diameter Capability: Forgings available up to 1700 mm in outer diameter and up to 7 tons per piece, suitable for rolling mill work rolls, and shafts.

• High Structural Strength: Forging ratio ≥ 3.0 ensures dense grain flow and enhanced mechanical properties under heavy rolling and compressive forces.

• Rough Machined Finish: Delivered in rough-machined condition, allowing for custom final machining based on assembly needs and tolerances.

• Thermal and Mechanical Stability: Optimized heat treatment improves core toughness, fatigue resistance, and dimensional stability under high temperatures.

Applications:

• Work roll and backup roll shafts for hot and cold rolling mills

• Transmission components for plate and strip rolling equipment

• Housing parts and support structures for steel and aluminum rolling mills

• Gear and coupling blanks for rolling line drive systems

Process flow:

raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
