Founded in 2010 in Tangshan, Hebei Province, Tangshan Runxing Machinery Co., Ltd. has established itself as a premier research-oriented manufacturer. We specialize in the development, production, and on-site engineering of high-performance hardfacing wear-resistant metal products designed to withstand the harshest environments globally.
Our dynamic metal surface engineering portfolio comprises premium chromium carbide overlay (CCO) wear plates, customized wear liners, hardfacing flux-cored welding wires, and fully integrated automatic hardfacing systems. Our operations are governed by a commitment to "Integrity, Superior Quality, Innovation, and Sustainable Development," providing the global industrial sector with robust defense systems against abrasive and corrosive media.
In modern heavy industrial applications, mechanical parts undergo severe tribological degradation. Structural steel alone is insufficient against the constant stress of abrasive materials, particulate wear, and high impact. This degradation costs the global mining, power generation, cement, and steel industries billions of dollars annually in premature downtime and equipment replacement. Metal carbide surfacing, particularly hypereutectic Chromium Carbide Overlay (CCO) coatings, provides a highly durable and wear-resistant solution. By metallurgically bonding a carbide-rich overlay to a ductile steel backing plate, engineers combine structural resilience with high abrasive wear resistance.
As heavy machinery operating parameters become increasingly demanding, procurement managers face several critical challenges when sourcing metal carbide solutions:
Tangshan Runxing Machinery Co., Ltd. addresses these challenges by supplying integrated wear solutions. Rather than offering basic off-the-shelf plates, we customize the alloy composition (e.g., adding Niobium, Boron, or Tungsten for high-temperature and high-impact conditions) to match the customer's specific operational environment. This approach extends equipment service life by up to 5 to 10 times compared to traditional quenched and tempered carbon steel plates.
Furthermore, our partnerships with academic institutions, including the metallurgy department at Tangshan University, ensure that our metallurgical R&D incorporates the latest innovations. By studying grain refinement and carbide orientation under different thermal cooling rates, our engineering team optimizes wear performance for our global partners.
Composite material wear plate made of a structural steel backing and a hard weld surfacing. RX®wp 7600 is a composite material made of structural steel backing and hard weld surfacing, corresponding to DIN 8555 specifications. Designed for heavy wear and high abrasive operations.
Self-shielded flux-cored wire. This high chromium alloy is specifically formulated to resist high-stress grinding abrasion with low impact. Excellent feedability and stable arc characteristics for rebuilding wear plates and heavy equipment surfaces.
Advanced PTA surfacing powder and system components. Delivers ultra-hard, homogeneous protection overlays with minimized base metal dilution. Ideal for precise industrial applications requiring fine tolerances and extreme corrosion resistance.
RX® Surfacing equipment features a high degree of automation, high welding efficiency, small footprint, and easy maintenance. Suitable for various wear-resistant composite steel plates, utilizing open-arc, submerged-arc, and solid/flux-cored wires. The advanced CNC system operates via a 10.2-inch touchscreen with four independently controlled welding guns.
Tailored structural fabrication, profile cutting, bending, and assembly of complex wear parts. RX® brings years of experience to fabricating custom-machined accessories, wear-resistant pipes, and fully integrated engineering components built to precise blueprints.
Comprehensive restoration services for grinding rolls and table segments used in steel, cement, power, and mining coal mills. We apply specialized hardfacing layers to rebuild worn profiles, significantly reducing operating costs and extending the lifecycle of heavy vertical roller mills.
Industrial operations are moving toward higher temperatures, faster throughput speeds, and highly corrosive materials. Conventional chromium carbide overlays face limitations when temperatures exceed 550°C (1022°F), as the chromium matrix begins to soften and lose its hardness. The current technology roadmap for wear prevention focuses on several key areas:
Industrial components must meet strict compliance and quality standards. Runxing Machinery is certified under major international quality systems. All exported wear plates and hardfacing consumables are manufactured in accordance with AWS and DIN 8555 standards.
To ensure smooth international trade, all export business is handled by Hebei Yuwan International Trade Co., Ltd. They manage customs clearance, international logistics, shipping documentation, and multi-currency transactions. This structured division of labor allows our manufacturing facility to focus entirely on maintaining high production standards and on-time delivery.
Cement plants rely on high equipment availability. Wear protection is key to reducing downtime; the performance of wear-resistant components determines the operating lifetime of critical machinery like raw mills and chute liners.
Global mining operations require high wear resistance to maintain profitability and sustainability. We supply cost-effective wear plates and liners that withstand heavy impact and abrasion during rock and ore extraction.
The steel industry involves harsh operating conditions, including high temperatures, heavy impact, and corrosive environments during mineral processing. Our alloys are engineered to extend the life of sintering and blast furnace parts.
We supply specialized wear protection components for coal pulverizers, boiler fan blades, conveyor chutes, and dust collection systems within coal-fired power stations.
Port loading and unloading equipment handles large volumes of bulk material. Our wear plates protect hopper bins and transfer chutes, reducing wear during ship-to-shore bulk transport.
We supply wear-resistant alumina ceramic components, made from high-purity alumina powder sintered at high temperatures, for applications requiring electrical insulation or chemical resistance alongside wear protection.
Our website, runxing-machinery.com, has entered its trial operation phase, serving as a procurement platform for wear-resistant products.
