Explore SeriesModern heavy infrastructure operates under extremely punishing conditions. The relentless friction, impact, heat, and corrosive forces in industries such as mining, steel production, cement manufacturing, and power generation account for billions of dollars in lost productivity and component wear annually. In this context, steel welding machines and hardfacing technologies are no longer secondary maintenance tasks; they are critical factors in maximizing equipment uptime and operational yield.
Historically, wear-prone machinery parts were simply replaced when worn down, resulting in massive material waste and system downtime. Today, the global manufacturing paradigm has shifted toward surface engineering. Through the deposition of advanced metallurgical overlays, such as chromium carbide and complex borides, onto structural carbon steel backings, the lifespan of industrial machinery can be extended by 300% to 800%.
This industrial transition is supported by the adoption of automated surfacing setups. Automated multi-cathode and CNC-driven steel welding machines allow factories to apply protective overlays with unmatched precision, consistent bead morphology, and minimal thermal distortion, setting a new standard for global wear management.
Tangshan, located in China's Hebei Province, serves as one of the world's densest metallurgical manufacturing hubs. This location grants direct access to primary steel resources, refined alloys, and highly specialized metal-forming research institutions. The close coupling between material science labs and industrial production sites guarantees rapid iteration of hardfacing products.
"Through Hebei Yuwan International Trade Co., Ltd., we streamline customs clearance, shipping logistics, and payment collection, allowing our production facilities to focus exclusively on product quality and delivery times."
Chinese hardfacing factories have leveraged regional industrial clusters to build highly integrated supply chains. Tangshan Runxing Machinery Co., Ltd., established in 2010, is a prime example of this development. By combining raw material processing, flux-cored wire drawing, and automated machine building under one roof, we significantly reduce operational overhead.
Furthermore, our close research partnership with institutions like Tangshan University (spearheaded by Professor Yang Yuehui's Metal Materials and Forming Technology team) injects advanced academic research directly into our shop floor operations. This collaboration ensures our wear plates, custom liners, and automated welding systems maintain metallurgical superiority while remaining highly cost-effective.
Through our dedicated trade partner, Hebei Yuwan International Trade Co., Ltd., we handle logistics, export documentation, and payment operations seamlessly, giving global buyers the peace of mind of a secure transaction alongside factory-direct pricing.
Our wear protection products are deployed globally to safeguard heavy machinery in high-friction environments.
Critical systems like raw vertical mills, conveyor chutes, and hopper liners suffer extreme abrasive wear. By applying our high-hardness CCO wear plates, cement operators can achieve continuous operation with fewer unscheduled outages.
Excavator buckets, draglines, and heavy mineral screens encounter abrasive ore impact. Our customized wear liners provide reliable protection to extend the service life of these high-value mining assets.
Blast furnace components and continuous casting rolls endure high temperatures, dynamic friction, and chemical corrosion. Our specialized roll repair services and custom flux-cored wires help maintain tight production tolerances.
Coal pulverizer grinding segments, fan impeller blades, and dust removal piping endure high-velocity particle impact. Runxing's hardfaced pipes provide reliable protection against localized wear.
High-volume stackers, reclaimers, and grab buckets process abrasive cargo daily. Outfitting these interfaces with CCO plates minimizes downtime and keeps port cargo operations running efficiently.
Where impact forces are low but friction is extremely high, we offer alternative solutions like high-purity alumina ceramics, which are sintered at high temperatures to provide robust wear performance.
The hardfacing sector is shifting toward digital integration. Today's manufacturing demands higher deposition efficiency and consistent quality, pushing the industry toward automated systems. Our RX® Surfacing Equipment features advanced CNC capability managed through a user-friendly 10.2-inch touch HMI. The machine operates with four welding guns that can work in sync or independently, ensuring flat and uniform weld beads across large plates or cylindrical shapes like grinding rolls.
Moreover, modern metallurgical science is turning to complex carbides—incorporating niobium, boron, and titanium alongside chromium. This enhances high-temperature stability up to 600°C, a crucial requirement for coke guides and sinter screens in modern steel production.

When selecting a hardfacing equipment and materials vendor, procurement teams should evaluate the following key indicators:
Runxing satisfies these requirements. We provide comprehensive documentation for our custom fabrications, bimetallic plates, and high-performance flux-cored wires, ensuring our products perform reliably in demanding field conditions.
Clear, professional answers to common questions about hardfacing, bimetallic CCO plates, and automated welding systems.
A CCO plate is produced by depositing a high-chromium, high-carbon alloy onto a ductile backing steel plate (usually Q235B or Q345B) using open-arc or submerged-arc welding processes. Under the high temperature of the arc, the alloy forms primary M7C3 chromium carbides within a tough eutectic matrix. The carbide volume fraction typically reaches 30-50%, providing high resistance to sliding abrasion, while the carbon steel backing absorbs impact and allows for easy installation via welding or stud bolting.
Our automated welding system features a four-gun configuration, enabling it to deposit overlay materials up to four times faster than single-gun machines. The system uses a high-performance CNC setup controlled via a 10.2-inch touch screen HMI. Operators can easily program swing welding speeds, stroke widths, and step distances to ensure uniform weld beads and minimize dilution from the base steel substrate.
Self-shielded flux-cored wires contain internal gas-forming elements and flux agents within their hollow core. During welding, the arc decomposes these components to generate a protective shielding gas envelope and a slag cover. This eliminates the need for external shielding gas cylinders, making it ideal for outdoor maintenance, windy job sites, and high-altitude locations where wind can easily disrupt gas flow.
