The rod chain’s high fatigue resistance ensures long service life (80,000+ operating hours under normal heavy-load conditions) 37.

🏭 Core Manufacturing Process & Professional Surface Treatment

1. Core Manufacturing Processes: Precision-Driven for Heavy-Load Reliability

• Thickened Stainless Steel Forging & Cutting: High-grade stainless steel ingots are forged into thickened blanks (side plates, connecting rods, bushings, rollers) using precision heavy-duty forging machines, enhancing material density and tensile strength. The blanks are cut into required sizes using CNC plasma cutting machines (dimensional error ≤±0.05mm) 47.
• Precision Heavy-Duty Machining: The forged blanks undergo precision machining: ① Side plates: CNC punching and grinding to ensure hole position accuracy (error ≤±0.02mm) and flat surface; ② Connecting rods: CNC turning and grinding to ensure surface roughness Ra ≤0.8μm and dimensional consistency; ③ Rollers: Precision rolling, quenching, and grinding to ensure smooth rotation and wear resistance. Machining precision directly determines the fit between components and heavy-load transmission stability 26.
• Heavy-Duty Heat Treatment: To enhance mechanical properties, the machined components undergo targeted heat treatment: ① 304/316L stainless steel: Annealing (1050-1150℃) to eliminate internal stress and improve toughness; ② 310S stainless steel: Solution treatment (1150-1200℃) to enhance high-temperature resistance; ③ Connecting rods & rollers: Quenching and tempering (850-950℃) + carburizing treatment to improve hardness (HRC 50-60) and wear resistance. The heat treatment parameters are intelligently controlled to avoid material deformation 58.
• Heavy-Duty Assembly & Riveting: The heat-treated components are assembled into rod chains using automatic heavy-duty assembly machines. The connecting rods and side plates are riveted using precision hydraulic riveting machines (riveting force ≥50kN) to ensure firm connection without loosening. After assembly, the rod chain is adjusted to ensure smooth bending and rotation. For ultra-heavy-load models, reinforced pins and double-side plates are adopted to enhance load-bearing capacity 9.
• Final Heavy-Load Inspection & Testing: The finished rod chain conveyor belts undergo comprehensive inspections, including dimensional accuracy, fit tolerance, tensile strength, and fatigue resistance. The belts are tested for 2000+ hours of continuous operation under 120% rated load to ensure stable performance. Static load tests (loading 150% rated load for 24 hours) are conducted to verify non-deformation. Only qualified products are allowed to leave the factory, and complete test reports are provided 9.

2. Professional Surface Treatment: Enhancing Wear & Corrosion Resistance

• Stainless Steel Surface Strengthening Treatment: ① Passivation Treatment: Use nitric acid + sodium dichromate solution to form a dense oxide film on the rod chain surface, enhancing corrosion resistance (extending salt spray resistance by 60%); ② Polishing Treatment: For food-related heavy-load conveying (e.g., large-scale food processing), the surface is polished to Ra ≤0.2μm, ensuring hygiene and easy cleaning; ③ Pickling & Blasting Treatment: Remove oxide scale and impurities on the surface after heat treatment, improve surface finish, and enhance coating adhesion 59.
• Special Wear-Resistant Coating Treatment (Optional): For extreme abrasive environments: ① Ceramic Coating: Enhances wear resistance and high-temperature resistance (up to 800℃), suitable for mining and metallurgy applications; ② Tungsten Carbide Coating: Improves surface hardness (HRC 70-80) and wear resistance, extending service life by 2-3 times; ③ Electroless Nickel Plating: Improves corrosion resistance and wear resistance, suitable for marine and humid industrial environments 68.
• Accessory Surface Treatment: Heavy-duty sprockets, tracks, and attachments adopt surface treatment matching the rod chain: ① Stainless steel accessories: Passivation and polishing treatment; ② Carbon steel accessories: Hot-dip galvanizing + powder coating to avoid rust and enhance wear resistance. All accessories are reinforced to adapt to heavy-load operation, ensuring safe and stable cooperation with the rod chain 37.

3. Strict Quality Control: Guarding Heavy-Load Reliability

• Raw Material & Component Inspection: Each batch of thickened stainless steel raw materials is tested for chemical composition (spectrometer) and mechanical properties (tensile strength tester, hardness tester). Machined components are inspected for dimensional accuracy and surface quality using coordinate measuring machines (CMM) 37.
• In-Process Quality Supervision: During forging, machining, and heat treatment, real-time inspections of material density, dimensional accuracy, and heat treatment parameters are conducted. During assembly, inspections of riveting firmness and rod chain rotation smoothness are performed. All inspection data is recorded and traceable 68.
• Final Performance Testing: Finished conveyor belts undergo comprehensive performance tests, including tensile strength, fatigue resistance (20,000+ cycles), corrosion resistance (salt spray test, ASTM B117), high-temperature resistance, and wear resistance. A 2% random sampling method is adopted for each batch, and complete SGS/Intertek test reports are provided for bulk orders 9.
