• Superior Forging (Free Forging): Enhances internal grain flow and mechanical properties for maximum durability.
• Heavy-Duty Capacity: Handles forgings from 100kg to 7000kg for diverse gearbox sizes.
• Custom Engineered: Precisely manufactured to your specific design and performance needs.
• High Durability: Excellent wear and fatigue resistance ensures long gearbox lifespan.

Application Areas

These robust alloy steel forgings are essential for industrial gearboxes in:

• Wind Energy: Main gearbox components.
• Heavy Machinery: Gearboxes for mining, construction, and large agricultural equipment.
• Power Generation: Reducers for turbines and generators.
• Marine & Shipbuilding: Ship propulsion and deck machinery gearboxes.
• Cement & Mining: Drive components for crushers and mills.
• Steel Mills: Gearboxes for rolling mills and processing lines.

The steel forgings production flow:

Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.
