High Precision Forged Large Steel Gears Forged Alloy For Metallurgy And Mining Gearboxes

High Precision Forged Gear for Metallurgy and Mining Gearboxes. Our high precision forged gears are specifically engineered for heavy-duty gearboxes used in metallurgy and mining industries. With superior strength, excellent dimensional accuracy, and outstanding fatigue resistance, these forged gears are built to perform under extreme load conditions and harsh environments.

Product Features of High Precision Forged Gear

• Superior Mechanical Properties
  Made from alloy steels like 42CrMo4, 18CrNiMo7-6, offering high tensile strength, wear resistance, and toughness under shock loads.

• Optimized Heat Treatment
  Custom heat treatment processes such as carburizing and quenching enhance surface hardness while preserving core toughness for fatigue resistance.

• Improved Internal Structure
  The forging process eliminates internal porosity and ensures a dense, uniform grain flow, which significantly boosts gear lifespan and reliability.

• Heavy Load & Low Noise Operation
  Designed for stable performance under high torque and variable speeds, with reduced vibration and noise, suitable for continuous operation.

• Custom Engineering Support
  We offer full customization in size, module, pressure angle, and material to meet specific gearbox requirements in harsh working environments.

Application Scenarios

• Steel Mills and Rolling Plants
  Used in gear reducers for rolling stands, continuous casting equipment, and cooling bed drives, where strength and heat resistance are vital.

• Underground and Surface Mining Machinery
  Integrated into heavy-duty gearboxes of crushers, conveyors, bucket wheel excavators, and dragline systems.

• Ore Processing and Pelletizing Equipment
  Critical components in power transmission systems of ball mills, rotary kilns, and pelletizing discs requiring consistent torque under load.

• Coke Oven and Sintering Lines
  Applied in drive systems for sintering machines, coke pushers, and transfer cars in steel production lines.

• Heavy Duty Material Handling Systems
  Utilized in large conveyors, hoists, and stacker-reclaimers that demand precision movement and continuous duty cycles.

Process flow:

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