Founded in 2010 in Tangshan, Hebei Province—the heartland of China's heavy metallurgical cluster—Tangshan Runxing Machinery Co., Ltd. has grown into an internationally recognized authority in the R&D, fabrication, and field construction of hardfacing wear-resistant metal products. Under the guidance of our business philosophy of “Integrity, Superior Quality, Innovation & Sustainable Development,” we have engineered a sophisticated catalog of chromium carbide overlay (CCO) wear plates, custom processed wear liners, wear-resistant pipe fittings, hardfacing flux-cored welding wires, and automated surfacing machinery.
We are a qualified agent for VAUTID Germany for six consecutive years (since 2019), incorporating high-alloy materials that guarantee extreme performance metrics under severe wear conditions. All global transactions and export logistics are authorized and handled by our dedicated trade partner, Hebei Yuwan International Trade Co., Ltd., leaving our production facility focused strictly on metallurgical consistency, rigorous QC standards, and on-time delivery.
Our composite wear plates feature a structural steel backing coupled with a hard weld surfacing layer. The premium RX®wp 7600 complies with strict DIN 8555 standards, guaranteeing resilience under sliding abrasion and shock loading.
Specially formulated self-shielded flux cored wires. These high-chromium alloys are structurally engineered to resist high-stress grinding abrasion with low impact. Ideal for overlay repairs and bucket re-manufacturing.
High-efficiency CNC surfacing equipment. Configured with a 10.2-inch interactive touch screen, 4-gun configuration operating simultaneously, and adjustable swing speeds. Ideal for fabricating bimetallic composite wear-resistant plates and rolling mill components.
Re-manufacturing continuous casting rolls, conveyor rolls, pulverizer table segments, mill rollers, and coal crushers. Runxing's hardfacing services significantly extend life cycles and decrease operational overheads for mining and power generation facilities.
Hardfacing materials have evolved beyond basic low-carbon steels to complex composite structures. In modern high-stress applications, typical wear mechanisms demand that we customize microstructure patterns within the weld deposit. At Tangshan Runxing, our R&D roadmap focuses on controlling primary chromium carbide precipitation to yield optimal mechanical performance.
The wear resistance of bimetallic overlays relies on the dispersion of primary M7C3 carbides inside a tough eutectic matrix. Standard hardfacing wires typically produce a carbide volume fraction (CVF) of 30-40%. Our R&D division, collaborating with the metallurgy department of Tangshan University, is pushing this boundary to 50% CVF by fine-tuning Carbon (C) and Chromium (Cr) stoichiometric ratios while avoiding macro-embrittlement.
To resist severe industrial impacts, we introduce micro-alloying elements like Niobium (Nb), Boron (B), Titanium (Ti), and Vanadium (V). These elements act as grain refiners, yielding complex carboborides that restrict crack propagation through the hardfacing interface. This results in stable performance in high-temperature environments up to 450°C.
As occupational safety standards tighten globally, our technology roadmap emphasizes the development of low-fume, self-shielded flux-cored wires. By adjusting the flux chemistry and mineral composition inside the core, we have managed to cut hexavalent chromium emissions in welding fumes, helping buyers meet strict environmental and workplace health guidelines.
Equipment availability determines a cement plant's profitability. We protect raw meal mills, cyclone separator cones, vertical mill tables, roller press shells, and guide vanes from harsh sliding abrasion.
Mine operators need high-durability solutions. Our custom wear liners, shovel buckets, chute liners, and crusher segments are engineered for high extraction rates and minimal downtime.
We supply high-temperature hardfacing wires and rolls for blast furnace charging systems, sinter plants, and hot rolling guides that undergo thermal fatigue and impact.
Our hardfacing materials protect critical fuel-handling systems, pulverizer pulverizing table assemblies, coal mill rollers, exhauster fans, and boiler fuel inlets.
Tangshan Runxing's production base integrates CNC machining, robotic multi-gun welding arms, and automated powder blending lines. By running automated operations, we eliminate structural variations associated with manual welding. Our 4-gun cladding lines keep heat input uniform, resulting in flatter wear plates, lower distortion, and consistent metallurgical binding with the base carbon steel.
In 2023, Dean Yuan Shaoqiang, Vice Dean Li Jing, and Professor Yang Yuehui (Team Leader of Metal Materials and Forming Technology) from Tangshan University visited our facility to formalize cooperative metallurgical research. This joint initiative accelerates the development of customized welding chemistries for specific geological conditions, giving our clients a solid performance advantage.
To support buyers worldwide, all export logistics, customs clearance, legal compliance, and multi-currency transactions are handled by Hebei Yuwan International Trade Co., Ltd. This division of labor allows our production teams to focus entirely on quality assurance, while global buyers benefit from streamlined logistics and transparent trade procedures.
We actively present our technology at mining exhibitions globally, including EXPOMIN 2023 in Chile and the South Africa International Construction & Mining Machinery Exhibition (Africa 2024) in Johannesburg. Connecting directly with plant managers helps us refine our products for real-world field conditions.
Industrial procurement teams look for more than low prices; they require consistent wear performance, supply security, and documentation. When sourcing from a Chinese factory, keep these four technical criteria in mind:
