Customized Forging Parts for Coal Mine Conveyor

The Customized Forging Parts for Coal Mine Conveyor produced by Henan Shuangzhi Machinery Equipment Co., Ltd. are manufactured to meet the operational demands of 17GL7-1 scraper conveyor systems. These parts undergo a controlled forging process that enhances hardness, strength, and service life compared to cast alternatives. The primary material used is high-carbon alloy steel, with a target hardness range of 45-52 HRC after heat treatment, consistent with industry standards for scraper components in heavy-duty mining environments. Surface flatness and oxide layer removal during heating are critical to achieving dimensional stability and wear resistance.

The forging process involves heating the blank to approximately 1100°C to optimize plasticity, followed by quenching in water at precisely controlled temperatures to avoid surface cracking. The company uses hydraulic forging hammers with sufficient impact energy to meet the deformation requirements of thick scraper blades, a step that older die-forging hammers could not reliably achieve. The resulting parts exhibit consistent grain structure and minimal internal stress, which reduces the risk of premature failure under cyclic loading. Typical material grades include 42CrMo4 or equivalent, with carbon content around 0.40-0.45% and chromium/molybdenum for hardenability.

These components are primarily purchased by coal mining operators in Asia, Eastern Europe, and Latin America who require durable scraper blades, link plates, and connecting pins for continuous conveyor systems. Buyers typically order in batches of 50-200 units depending on conveyor overhaul schedules. Trade terms are generally FOB Jiaozuo Port, with packaging in wooden crates and protective oil coating to prevent corrosion during transit. Lead times are approximately 25-35 days after deposit, subject to order volume and material availability.

Henan Shuangzhi Machinery Equipment Co., Ltd. operates from Haojiang Steel Structure Logistics Park in Wuzhi County, Jiaozuo City, Henan Province, China. The company specializes in custom forging for coal mining equipment, with a focus on scraper conveyor components such as blades and links. Their facility uses hydraulic forging hammers to achieve the energy levels required for thick-section forgings, addressing limitations of older die-hammer systems. The listing confirms no certifications, no export history, and no third-party verification beyond a basic harbor trust tier.

There is no public information on company size, revenue, years in operation, or client names. The description references technical process knowledge but does not claim ISO certification, export volume, or production capacity. The supplier responds to inquiries with technical details about forging parameters, suggesting operational expertise but no formal quality management system is stated. Buyers should treat this as a manufacturer with process-specific knowledge, not a certified distributor or large-scale exporter.
