See more products →In modern heavy industries—such as mining operations, cement production facilities, steel plants, power stations, and bulk ports—the critical structural surfaces of machinery undergo extreme, unrelenting tribological stress. The primary failure mechanism is high-stress grinding abrasion coupled with low-to-medium impact force. This wear degrades component structural integrity, which results in unscheduled downtime, compromised production efficiency, and massive capital expenditures on component replacement.
Global enterprise buyers are shifting their strategic focus from standard corrective maintenance to high-efficiency preventive surfacing systems. High-quality automated flux welding machines, in conjunction with high-alloy flux-cored wires, represent the state-of-the-art solution to extend the wear life of equipment. Procurement processes demand precise compliance with metallurgical and thermodynamic specifications. Modern organizations look beyond generic systems; they prioritize parameters such as high dilution control, precise heat input management, automated tracking, and high deposition rates to maintain competitive throughput.
Additionally, the globalization of raw materials has raised the standard for welding system reliability. Multi-national corporations demand manufacturing partners who provide modular solutions capable of deposition across varying metal backings—whether standard carbon steel, low-alloy structural steel, or high-manganese cast alloys. System integration with local robotic arms, positioners, or mechanical gantries is essential to modern automated wear-plate cladding plants.
At the center of automated hardfacing is the control system of the surfacing machine. Our high-efficiency systems utilize high-end numerical control architectures integrated via responsive 10.2-inch industrial touch screens. This human-machine interface (HMI) allows operators to fine-tune crucial welding parameters dynamically, including swing speed, swing oscillation width, overlapping index, step-over distance, feed rate, and output current-voltage characteristics.
Our flag-ship RX® Surfacing Equipment features a multi-arc design, supporting up to four welding heads that can operate independently or simultaneously. This design provides maximum operational flexibility, enabling standard open-arc cladding, submerged-arc cladding, or addition-powder cladding to achieve high deposit thickness in a single pass without inducing excessive thermal deformation in the substrate plate.
The performance of bimetallic chromium carbide overlay (CCO) wear plates rests on the chemical makeup of the weld deposit. Using high-chromium self-shielded flux-cored wire creates a microstructural matrix packed with primary M7C3 chromium carbides (where hardness ranges between 1200 and 1600 HV). The surrounding tough austenite matrix supports these carbides, providing outstanding resistance to severe grinding abrasion under high stress.
Furthermore, our technology addresses a core challenge of cladding: base metal dilution. Standard manual welding methods can dilute the overlay alloy with the substrate metal, reducing the chromium concentration at the surface. Our automated flux welding machines use optimized current paths and controlled oscillation to keep base metal dilution below 10%, ensuring the top layer retains its high-hardness properties.
Founded in 2010 and situated in Tangshan, Hebei Province—the heartland of China's heavy steel production—Tangshan Runxing Machinery Co., Ltd. is a leading manufacturer specializing in the research, development, production, and site-application of hardfacing wear-resistant metal products.
Our comprehensive production facility focuses on high-durability chromium carbide overlay (CCO) wear plates, custom-fabricated wear liners, pipes, fittings, flux-cored welding wires, and automated surfacing machinery. For over six consecutive years, we have served as an authorized agent for VAUTID brand welding materials in Germany, integrating European metallurgical standards with efficient manufacturing capabilities.
Our global operations are managed through Hebei Yuwan International Trade Co., Ltd., which oversees customs clearances, global shipping logistics, legal compliance, and international payment transactions, ensuring a smooth, secure process for customers worldwide.
Our technologies are deployed across diverse sectors to extend equipment life, improve performance, and protect structural components.
Wear protection for critical cement processing equipment. Our CCO wear plates and on-site roller repairs protect cement vertical mill rolls, separator vanes, and chute liners against raw mineral abrasion, maximizing uptime.
Heavy-duty solutions for haul truck bed liners, bucket lips, hopper systems, and sizing screens. Runxing wear plates are designed to withstand high impact forces and aggressive friction from crushed ores.
Protection against high temperatures and corrosive environments. We restore casting rolls, guide rollers, blast furnace chutes, and conveyor plates, improving wear-life under severe thermal conditions.
Extended service life for coal handling systems. Our technology protects exhaust fans, pulverized coal pipelines, classifier cones, and burner nozzles from erosive ash and coal dust stream wear.
Enhanced protection for high-volume transfer facilities. We reinforce hopper linings, loading chutes, grab buckets, and dredge pump components against continuous sliding abrasion from sand and gravel.
Runxing Machinery maintains strong relationships with academic partners and international customers, demonstrating our commitment to quality across global forums.

Review event insights →The hardfacing industry is shifting toward higher automation, real-time closed-loop monitoring, and advanced alloy development. Tangshan Runxing Machinery is focusing its development on three primary areas: system intelligence, additive manufacturing materials, and eco-friendly processing methods.
First, we are integrating laser vision sensors with our automated welding gantries. These sensors perform real-time weld pool profiling, tracking, and groove width detection. This allows the system to adjust variables like welding current, travel speed, and oscillation width on the fly, ensuring a consistent overlay thickness regardless of base plate surface variations.
Second, we are developing complex-carbide alloy compositions. By adding elements like Niobium (Nb), Boron (B), Titanium (Ti), and Tungsten (W) to standard chromium iron formulations, we produce a dense array of multi-component carbides. These materials offer improved resistance to fine particle abrasion under high temperatures, exceeding the limits of traditional chromium-only alloys.
Global supply chains require reliable quality control and clear documentation. Tangshan Runxing Machinery manages its international trade through Hebei Yuwan International Trade Co., Ltd., ensuring compliance with all export and destination regulations.
Our export processes include comprehensive quality checks, detailed material test reports (MTRs), and certifications confirming compliance with ASTM G65 abrasion testing standards and DIN 8555 welding specifications. We use robust export packaging, structural steel reinforcing, and moisture protection to prevent rust during sea and rail transport.
Through our trading partner Hebei Yuwan, we manage all logistics processes—including customs declarations, freight booking, export documentation, and flexible payment arrangements—providing a reliable supply chain from our manufacturing plant to your facility.
