Designed specifically for large-scale gold dredging vessels, these chain plates are crafted from alloy steel forging with surface quenching, achieving a hardness of HRC55-60—3 times more wear-resistant than standard plates. Each link undergoes ultrasonic flaw detection to ensure zero internal defects, with a tensile strength ≥850 MPa to withstand continuous high-intensity sand and gravel impact. The unique self-cleaning link structure prevents sediment buildup, minimizing chain jamming risks. Ideal for bucket-chain and drag-head dredgers, real-world applications in the Yangtze River gold mining region have demonstrated a service life exceeding 18 months (compared to just 6-8 months for conventional plates). Customization is available for non-standard widths (300-1200mm) and pitch lengths (150-500mm).
