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.
