Beam/Press Plate for Coal Mining Conveyor

Henan Shuangzhi Machinery Equipment manufactures beam and press plates for coal mining scraper conveyors, with production based in Wuzhi County, Jiaozuo City, Henan Province. The component material is specified as 40Cr, a Chinese alloy structural steel comparable to AISI 5140, characterised by medium carbon content with chromium addition for improved hardenability and wear resistance. The beam functions to press the chain onto the scraper, secured by single-head bolts as part of the assembled scraper chain in the conveyor's central trough. Two production processes are offered: forging and casting, with forged variants exhibiting superior strength, toughness, and mechanical properties.

The 40Cr material specification implies quenching and tempering heat treatment to achieve typical tensile strength of 980 MPa and yield strength of 785 MPa in the hardened condition, though buyers should request the supplier's actual heat treatment certificate. Forged beams undergo directional grain flow that improves fatigue resistance under cyclic loading from the conveyor chain. Cast alternatives may offer cost savings and complex geometry but generally exhibit lower impact toughness and greater internal defect risk. The working position in the mid-section of the scraper conveyor subjects the beam to abrasive wear, impact from coal lumps, and tensile stress from chain tension.

These components are essential wear parts for armoured face conveyors and stage loaders in underground longwall and room-and-pillar mining operations. Buyers include mine operators, equipment maintenance contractors, and coal machinery rebuilders in China and export markets. The supplier indicates willingness to discuss purchase requirements directly. Exact MOQ, pricing, and lead time are not stated and require confirmation. Buyers should specify whether their application requires forged or cast construction, and provide the original equipment manufacturer part number or dimensional drawing for interchangeability verification.

Henan Shuangzhi Machinery Equipment Co., Ltd. is located at Haojiang Steel Structure Logistics Park, Wuzhi County, Jiaozuo City, Henan Province, 454950, China. This places the supplier within a central China logistics corridor with established steel processing infrastructure. The company holds a 'harbor' trust tier, with a response rate of 0.00 and zero recorded average response hours, indicating limited platform engagement metrics are available. No employee count, annual revenue, year of establishment, or production floor area is provided in the source data.

The source description reveals technical familiarity with coal mining machinery, specifically scraper conveyor components and their functional roles within the chain traction system. The supplier distinguishes between forging and casting processes and understands the mechanical property implications, suggesting engineering involvement in sales. However, no ISO certification, quality management system, or patent information is mentioned. Buyers should request business licence, factory inspection video, and sample test reports before committing to volume orders. Direct technical discussion about 40Cr heat treatment protocols and dimensional tolerances is advisable to assess capability.
