Engineering Precision for Abrasive Ash, Cement & Mining Conveyors
High-Density Alloy Steel Casting: Cast from premium manganese and alloy steel with strict defect-free metallurgical controls, ensuring maximum link toughness and immunity to shock fracturing.
In-House Heat Treatment & Case Hardening: Pins, barrels, and drag wings undergo specialized quenching, tempering, and surface induction hardening to achieve deep wear-resistant casing while maintaining core ductility.
100-Ton Tensile Verification: Every batch of JINQIU cast drag chains undergoes factory pre-stretching and dynamic tensile testing up to 100 tons to guarantee strict pitch consistency and eliminate early elongation.
50+ Professional Engineers: Our expert technical team provides rapid CAD design support, custom drag wing attachment modeling, and seamless interchangeable fits for major OEM conveyor systems.
Engineered for Power Plants, Cement Clinker & Mining Scraper Conveyors
Unplanned downtime caused by worn drag chains in power generation or cement production incurs severe operational losses. JINQIU’s cast drag conveyor chains feature wide wear surfaces, self-cleaning barrel designs, and hot-dip synthetic pre-lubrication to withstand abrasive clinker, fly ash, and mineral ores. Partnering directly with China's leading chain source ensures global distributors receive competitive factory-direct pricing, stable bulk supply, and complete OEM/ODM custom manufacturing services.
