In the modern heavy industry segment, wear and mechanical degradation account for up to 70% of unexpected equipment downtime in cement plants, coal mines, steel mills, and dredging ports. Traditionally, worn components were replaced entirely, creating massive capital expenditure (CapEx) burdens. Today, global industrial frameworks are shifting toward circular manufacturing and predictive maintenance, making Flux-Cored Arc Welding (FCAW) surfacing automation the preferred strategy for wear protection.
The global FCAW welding machine market has evolved from simple manual operations to high-throughput, multi-axis CNC cladding systems. Heavy equipment operators now require automated machinery capable of depositing dense, high-chromium carbide overlays (CCO) onto low-carbon steel substrates. As a dedicated wholesale manufacturer, Tangshan Runxing Machinery Co., Ltd. builds advanced overlay automation equipment designed to produce consistent bimetallic wear liners that prolong component lifetimes by up to 500%.
Our technology incorporates precision CNC parameters, automated voltage controls (AVC), and oscillation controls. These features allow operators to optimize deposit chemistry, control dilution with the base metal, and achieve flawless stress-relieving crack patterns (cross-checking) necessary for CCO bimetallic plates.
Composite material wearplate made of a structural steel backing & a hard weld surfacing. Our signature RX®wp 7600 is a premium composite material made of a structural steel backing and a hard weld surfacing, corresponding to DIN 8555 specifications. It provides an optimized distribution of primary chromium carbides (Cr7C3) in an austenitic matrix, delivering exceptional protection against severe mineral scratch abrasion.
Self-shielded flux cored wire. Formulated as a high chromium alloy designed specifically for resisting high-stress grinding abrasion with low-impact conditions. These wires generate their own shielding gas during combustion, making them highly versatile for field applications where external gas cylinders are impractical. Ideal for overlaying wear plates, hopper liners, and heavy excavation buckets.
Plasma Transferred Arc (PTTA) technology offers precision alloy deposition. By focusing a plasma arc through a copper nozzle, this system deposits specialized metal powders and flux-cored wires onto the base material with minimal dilution. It is the ultimate choice for critical industrial surfaces requiring thin, highly concentrated wear-resistant coatings.
RX® Surfacing Equipment features a high degree of automation, high welding efficiency, small footprint, easy maintenance, and optimized power consumption. It is engineered for producing wear-resistant composite steel plates and repairing heavy rollers. The system accommodates solid-core, flux-cored, and self-shielded wires under open-arc, gas-shielded, or submerged-arc configurations. With a centralized 10.2-inch touch screen CNC interface, the welding mechanism drives four welding guns simultaneously or independently. Speed, swing path width, and welding parameters are fully adjustable to ensure flawless surface overlays.
RX® possesses extensive experience and engineering solutions for heavy machining, customized accessory fabrication, and turn-key mechanical projects. We take bimetallic sheets and transform them through CNC plasma cutting, rolling, press-braking, and specialized structural fabrication. This process creates high-precision liners, curved pipes, and cyclone separators designed to drop directly into existing customer plants.
Grinding rolls are critical components in vertical raw mills (VRM) and coal crushers across power plants and cement factories. The lifespan of these rolls directly affects milling efficiency and operating costs. RX® offers advanced on-site and in-shop roller surfacing repair services. Utilizing high-hardness chromium-molybdenum-boron alloy wires, we rebuild grinding surfaces back to their original geometry, restoring mill productivity and cutting energy losses.
Tangshan Runxing Machinery Co., Ltd. is a professional manufacturer located in Tangshan, Hebei Province, that focuses on the R&D, production, and on-site construction services of hardfacing wear-resistant metal products. Founded in 2010, we have spent over a decade refining our metallurgy and automation processes.
Our core product catalog encompasses chromium carbide overlay (CCO) wear plates, custom processed wear liners, wear-resistant pipes and pipe fittings, hardfacing flux-cored welding wires, automatic hardfacing welding machines, and professional roller surfacing repair services. We follow the core business philosophy of "Integrity, Superior Quality, Innovation & Sustainable Development" and maintain mature, advanced metal surface hardfacing technologies.
We supply tailored wear solutions to cement, steel, mining, power generation, and port dredging operations worldwide, with a strong market reputation established in Russia and Central Asia.
Note: All export operations are managed by Hebei Yuwan International Trade Co., Ltd. This authorized trade entity handles customs clearance, international shipment logistics, legal documentation, and secure payment collection, allowing our factory to focus entirely on R&D, product quality assurance, and on-time delivery.
Operational availability of equipment is the key metric for cement plants. Raw materials like limestone, clay, and clinker cause extreme abrasive wear. We supply hardfaced vertical mill rollers, separator vanes, chuting systems, and raw material feed hoppers that keep plants running continuously, preventing unscheduled kiln shutdowns.
Mine operators globally face intense pressure to improve productivity, safety, and operational margins. From shovel buckets and truck beds to chute liners and vibrating screen plates, our wear-resistant chromium carbide overlays shield equipment from heavy ore friction, lowering wear-related replacement costs.
Working conditions in steel plants are severe, combining abrasive iron ore sinter, slag, coke, high temperatures, and chemical corrosion. Our specialized high-temperature CCO plates and hardfaced guide rollers withstand extreme thermal cycles and abrasive friction, maintaining process efficiency.
Thermal power plants require continuous coal feeding and ash removal. We manufacture hardfaced linings for coal mill pulverizers, fan blades, exhaust blower housings, hopper liners, ash sluice pipes, and crusher hammers, protecting critical paths from high-velocity particle erosion.
Bulk ports transport millions of tons of sand, coal, grain, and iron ore annually. Unloading hoppers, conveying chutes, bucket grab lips, and dredging pipe elbows experience heavy sliding wear. Custom RX® CCO liners and pipe sleeves prevent abrasive blowout, ensuring uninterrupted shipping operations.
For application environments with lower impact force but extreme high-frequency abrasion, we offer high-purity alumina ceramics. Sintered at high temperatures with an optimized chemical formula, these ceramic liners are bonded to metal substrates via advanced epoxy adhesives, providing an excellent alternative to CCO plates in specific system areas.
The future of hardfacing lies in precision spatial welding. Tangshan Runxing Machinery is developing its next generation of multi-axis robotic cladding stations. These systems utilize machine vision to scan worn components (such as vertical grinding rollers or curved screw conveyors) and automatically adjust welding parameters, nozzle distance, and oscillation width in real time.
By working with international alloys (such as German VAUTID materials), we are designing wires that form complex boron-carbide and niobium-carbide matrices. These advanced alloys offer wear protection at high operating temperatures (up to 750°C), supporting applications in hot sinter plants and coal gasification vessels.
Rebuilding worn components consumes only 10% to 20% of the energy needed to manufacture new steel parts from scratch. Runxing's automatic hardfacing machines feature high-efficiency inverter power modules and open-arc configurations. By eliminating external shielding gases and reducing slag generation, our machinery minimizes the carbon footprint of industrial operations.
