Stainless steel double-pitch chain hard-core responsibility of industrial transmission

Stainless steel double-pitch chain: hard-core responsibility of industrial transmission

As the core component of industrial transmission, stainless steel double-pitch chain has become the preferred solution for high-load scenarios with its structural design and material process advantages. The following analyzes its technical characteristics and application value from five dimensions:

1. Double-pitch design breaks through space limitations
By increasing the pitch by 2-3 times, the long-distance transmission and space occupation balance can be achieved. In scenarios such as glass annealing furnaces and metal heat treatment, the number of sprockets can be reduced and the transmission system can be simplified, while ensuring the stability of power output.

2. Material and technology to build performance foundation
Material selection: 304/316L stainless steel and high-strength carbon steel are used, and 316L passes the 480-hour acid salt spray test; 1Cr13 heat-resistant steel can be selected for special working conditions, and the chain plate hardness reaches HRC38-42 after quenching at 1200℃.
Core process: Heat treatment forms ferrite + pearlite structure, hardness of 146-165HBW; cold rolling process makes the surface roughness reach Ra0.8μm, and the friction coefficient is reduced to 0.12; the electroplated nickel-chromium alloy layer passes a 480-hour neutral salt spray test, and the corrosion resistance is increased by 4 times.

3. Performance advantages adapt to heavy load requirements
High load capacity: The double-row sprocket structure can withstand tensile forces of several tons, and the actual measurement of automobile stamping line does not have plastic deformation for 2,000 hours.
Fatigue resistance and stability: the pitch growth is ≤0.3%/1000h, and the annual operating error of metallurgical equipment is controlled within ±2mm.
Easy maintenance design: The modular link supports rapid disassembly and assembly, and combined with special lubricants, the maintenance frequency of food companies has been reduced from twice a week to once a month.

4. Scenario-based applications cover multiple industries
Food processing: M series conveying chain (pitch 50.8mm) realizes the delivery of 3,000 pieces of bread per hour, complies with FDA standards.
Logistics sorting: The combination of FV chain and 180° turning mesh belt supports the diversion of 12,000 pieces of goods per hour in JD Logistics.
Industrial kiln: Custom heat-resistant chains are continuously operated at 1150℃ in Baosteel for 5000 hours without breaking.
Environmental protection equipment: The chain for sludge scraper has increased corrosion resistance by 300% in 200ppm chloride environment.
