Explore DetailsThe core wear performance of our Chromium Carbide Overlay (CCO) plates lies in the microstructural formation of hypereutectic primary M7C3 chromium carbides. Sintered within a resilient eutectic matrix, these carbides exhibit a hardness exceeding 1500 HV, providing a barrier that prevents micro-ploughing and abrasive micro-cutting by quartz and mineral particulates.
Under heavy sliding friction conditions, raw silica sand, iron ore, sinter, and clinker apply shear forces to steel walls. Regular carbon steel yields immediately. Our composite wear plate designs leverage a tough structural backing plate (such as ASTM A36 or Q235B) to absorb systemic shocks, while the overlay handles the friction, extending service life by 5 to 10 times.
For more than six consecutive years, Tangshan Runxing Machinery Co., Ltd. has maintained a collaborative agency and materials integration agreement with Germany's world-leading brand, VAUTID. Combining German metallurgical formulations with Chinese engineering scale allows us to deliver high-tier hardfacing alloys globally.
Modern material handling systems in mining, cement kilns, fossil-fuel power stations, and deepwater ports handle millions of tons of heavy aggregates annually. The resulting material friction cost is one of the highest operating expenditure (OpEx) variables in large-scale infrastructure. Unscheduled downtime caused by a ruptured raw feed chute or worn grinding roll can cost operators hundreds of thousands of dollars per hour in lost output.
This is where precision-engineered hardfacing solutions provide a high return on investment. Rather than continuously replacing entire structural elements, the application of overlay plates and localized refurbishment reduces base steel costs. Runxing Machinery coordinates with procurement officers and maintenance engineers across Europe, Central Asia, and Africa to analyze wear patterns, offering customized metallurgical grades optimized for specific abrasion rates, chemical corrosiveness, and ambient process temperatures.
Operating from Tangshan, Hebei Province—the geographic heart of China’s steel production ecosystem—Tangshan Runxing Machinery Co., Ltd. maintains a strategic geographic advantage. We source raw base plate materials, alloy additives, and carbon carriers directly from surrounding primary steel mills. This enables us to maintain structural material supply chains even during global market shifts.
Furthermore, all international commerce and supply logistics are coordinated through Hebei Yuwan International Trade Co., Ltd. This trade integration ensures compliant customs clearance, secure payment terms, and direct sea/rail logistics. For heavy industrial operations, the close proximity to Tianjin Port enables fast, low-cost freight routing, ensuring that critical wear liners reach global ports on schedule and fully cleared for delivery.
Critical systems like vertical mill rolls, classifier cones, fan blades, and raw meal chutes suffer constant sliding abrasion. Integrating our CCO plates increases continuous kiln runtime by protecting materials handlers from premature wear failure.
Ore extraction exposes chute liners, dump truck bodies, and bucket teeth to intense gouging impact. Runxing's high-hardness CCO wear liners are designed to resist impact fracture while maintaining hard surfaces under high pressure.
Ironmaking blast furnace bins, coke distributor guides, and sinter screen decks must handle hot, raw materials. Our high-temperature wear alloys maintain structural integrity even under extreme thermal stress.
Coal processing systems, hopper liners, pulverizer parts, and fly ash exhaust fans handle continuous abrasive streams. Our overlay tubes and plates prevent wall wear, helping to eliminate fuel line leaks.
Bulk conveyor systems, hopper funnels, grab buckets, and suction pipes handle abrasive sand and wet minerals. Standard carbon steel corrodes and wears quickly; our CCO plates provide targeted protection against both issues.
For high-velocity sliding wear, we sinter high-purity alumina ceramics into metal matrices. This provides a hard surface for piping elbows and material sorting applications where steel alone faces wear limits.
Founded in 2010 and located in Tangshan, Hebei Province, Tangshan Runxing Machinery Co., Ltd. specializes in the R&D, manufacturing, and on-site repair of hardfacing wear-resistant metal products.
We produce chromium carbide overlay (CCO) plates, custom processed wear liners, wear-resistant pipes and fittings, hardfacing flux-cored wires, and automated surfacing machinery. By utilizing advanced metal surface hardfacing techniques, we supply reliable wear protection systems to global industries, including mining, cement, power, and port transport.
Our academic and technical partnerships support our manufacturing capabilities. In 2023, leaders from Tangshan University—including Dean Yuan Shaoqiang, Vice Dean Li Jing, and Professor Yang Yuehui (Metal Materials and Forming Technology team)—visited our facility. This ongoing research partnership supports our product development and QA standards, helping us deliver stable products that meet international specifications.
To ensure smooth international trade compliance, all global transactions, shipping documentation, letters of credit, and customs procedures are handled by our export division, Hebei Yuwan International Trade Co., Ltd. This structure allows our production facility to focus on metallurgy and quality control while maintaining reliable delivery times.
Participating in the South Africa International Construction and Mining Machinery Exhibition, we showcased our specialized CCO plates and portable wire feeders for deep gold and platinum mining applications across the African continent.
We presented our high-hardness mining liners and custom bimetallic overlay components in Chile, expanding our wear solutions for large-scale mining operations in South America.
Maintaining active agency status with VAUTID Germany for six consecutive years confirms that our processing methods and materials meet strict quality guidelines for high-wear environments.
The demand for longer machine runtimes is pushing wear technology beyond traditional steel plates. Our R&D team, in partnership with academic institutions, focuses on two key development paths:
Our wear plates and hardfaced layers undergo strict quality testing to verify consistent wear performance:
Equipped with a CNC 4-gun setup and a 10.2-inch touch screen interface, this system is designed for high-efficiency wear plate fabrication and roll cladding.
