Forged Chain
Drop-forged chain is a high-strength transmission component manufactured through precision die-forging technology. Utilizing premium alloy steel as raw material, it undergoes a series of processes including heating, die pressing, and heat treatment. Compared to traditional cast or welded chains, drop-forged chains exhibit a denser metallic grain structure and superior mechanical properties, making them ideal for heavy-duty, high-speed, and high-precision industrial drive systems.
The production process employs computer-controlled forging equipment to ensure dimensional accuracy and consistency of each chain link. By adjusting die designs, the chains can be customized to meet varying load requirements and operational conditions.
1. Ultra-High Strength
The drop-forging process eliminates internal material voids and defects, achieving tensile strength over 1.5 times that of conventional chains. For example, Grade G80 drop-forged chains exhibit breaking loads exceeding 800MPa.
2. Wear and Fatigue Resistance
Surface carburizing or quenching treatment ensures hardness of HRC 55-60, extending service life by 30-50% in harsh environments like mining and metallurgy.
3. Precision Compatibility
With link tolerances controlled within ±0.1mm, these chains are ideal for precision transmission equipment (e.g., automated production lines), preventing tooth jumping or chain jamming.
4. Safety and Reliability
Featuring no welded weak points and excellent dynamic load capacity, the chains comply with international certifications.
5. Lightweight Design
Offering 15-20% weight reduction compared to traditional chains at equivalent strength, significantly reducing equipment energy consumption.
1. Heavy Industry: Bucket elevators for mining, drive systems for metallurgical rolling mills, and grab buckets for port ship unloaders.
2. Energy Equipment: Yaw systems for wind turbine generators, lifting mechanisms for oil drilling platforms.
Automated Logistics: Sorting lines for intelligent warehouses, traction chains for AGVs (Automated Guided Vehicles).
3. Special Applications: Maintenance robots for nuclear power equipment, marine anchor chains (with salt spray corrosion-resistant treatment).
With their structural strength and reliability, drop-forged chains are increasingly replacing conventional chains as the preferred solution for high-end industrial power transmission.
