Founded in 2010 in the heavy industrial heartland of Tangshan, Hebei Province, Tangshan Runxing Machinery Co., Ltd. has established itself as an elite global manufacturer dedicated to the research, development, and on-site engineering of high-performance hardfacing wear-resistant metal products.
Our core capabilities encompass the manufacturing of Chromium Carbide Overlay (CCO) wear plates, custom-fabricated wear liners, abrasion-resistant pipe fittings, and high-alloy self-shielded flux-cored welding wires. Runxing’s metallurgical engineers implement advanced surface coating solutions that significantly extend the service life of critical components across primary industries including cement, steelmaking, mining, port logistics, and power generation.
To ensure structural execution and supply chain transparency, all export operations are managed by our authorized subsidiary, Hebei Yuwan International Trade Co., Ltd. This dedicated trade house handles complete customs compliance, ocean logistics, trade documentation, and global payments. This operational structure allows our manufacturing plants to focus exclusively on product development, precision quality control, and schedule reliability.
In modern mineral extraction, bulk material logistics, and thermodynamic power generation, mechanical systems undergo continuous degradation due to high-stress abrasive contact, severe erosive flows, and thermomechanical stresses. Under these conditions, standard carbon steel and low-alloy steels suffer from accelerated wear, leading to unplanned downtime, high maintenance overheads, and severe production losses.
Shielded welding wires (specifically flux-cored arc welding wires or FCAW) provide the metallurgical foundation for repairing and reinforcing these critical assemblies. By introducing alloying agents—such as Chromium (Cr), Carbon (C), Manganese (Mn), and Niobium (Nb)—directly into the hollow core of the wire, engineers can deposit high-density primary carbides ($M_7C_3$) within a resilient martensitic matrix. This composite micro-structure acts as a defensive barrier, dissipating kinetic and frictional energy while retaining structural integrity under high heat conditions.
Self-shielded flux-cored wire (FCAW-S) contains gas-forming compound fluxes directly within the wire core. Under the heat of the electric arc, these compounds vaporize to form a localized shielding gas envelope, eliminating the need for external shielding gas cylinders. This technology is highly beneficial for open-air structural builds, remote mining sites, and high-altitude weld assemblies where high wind conditions render gas-shielded processes ineffective.
Gas-shielded flux-cored wire processes utilize external shielding gases (typically 100% $CO_2$ or an Argon-$CO_2$ mix) to isolate the weld puddle from atmospheric nitrogen and oxygen. This method ensures exceptionally clean weld metal chemistry, high deposition rates, and deep joint penetration. It is ideal for precision factory fabrication of heavy CCO plates and automated structural welding setups.
For large-scale, automated flat-position surfacing (such as heavy mill roll rebuilding and wide wear plate manufacturing), tubular SAW wires are used in combination with granular mineral flux. This configuration achieves deposit rates exceeding 10 kg/hr with near-zero spatter, generating thick cladding layers with minimal dilution of the base material.
Tangshan, located in northern China's Hebei Province, is a major global steel-producing hub. Operating within this industrial cluster gives Tangshan Runxing Machinery Co., Ltd. major competitive advantages in supply chain integration and cost efficiency:
Cement manufacturing involves continuous abrasive wear from raw materials and clinker. Key components require wear-resistant cladding to prevent premature failure. Our hardfaced CCO plates and self-shielded welding wires are used to reinforce:
• Vertical raw mill grinding rollers and tables.
• Chute liners and raw meal hopper guides.
• High-temperature cyclone separator liners and exhaust fan blades.
Mining operations require robust impact and slide abrasion protection. High stress grinding abrasion combined with impact forces damages bucket teeth, shovel liners, and chute walls.
• Custom-processed wear liners for dump truck bodies.
• Rebuilding worn dragline buckets using high-alloy flux-cored wires.
• Hardfaced sizing screens and primary crusher plates.
Steel plants expose machinery to abrasive particles and high temperatures. Runxing alloys maintain hardness at elevated temperatures, providing protection for:
• Blast furnace bell and hopper assemblies.
• Sintering plant screen plates and coke guide plates.
• Continuous caster conveyor rolls repaired using submerged arc welding (SAW) wires.
Coal handling systems require continuous protection against sliding abrasion. Our materials are applied to:
• Coal pulverizer grinding rolls and table liners in power plants.
• Port grab buckets and hopper liners for coal, iron ore, and clinker.
• Heavy conveyor transfer chutes and screw feeders.
The field of surface engineering is shifting from standard high-chromium alloys to complex carbide systems designed for specific high-wear environments. Runxing's metallurgical research and development focuses on three primary technological advancements:
Critical equipment availability relies on wear protection. Our high-chromium CCO wear plates help plants extend maintenance intervals and prevent unexpected wear-related shutdowns.
Global mining operations require highly cost-effective wear protection. Runxing CCO liners and hardfacing wires provide long-term protection against impact and sliding abrasion.
Steel plants subject equipment to extreme conditions including abrasive raw minerals, high operating temperatures, and corrosive environments. Runxing alloys are designed to withstand these parameters.
We provide localized wear protection for fan blades, conveyor chutes, hopper liners, coal pulverizers, dust collectors, and coal ash conveying systems.
Ports transport high volumes of abrasive dry materials. Our wear-resistant liners protect ship loaders, grab buckets, stacking equipment, and reclaimers to optimize handling efficiency.
We also utilize high-purity alumina ceramics, sintered at high temperatures under optimized formulations, to protect components subjected to extreme particulate erosion.
To serve the global wear-resistant market, www.runxing-machinery.com has entered its trial operation phase. The portal provides convenient procurement options and technical documentation for global engineering firms seeking wear-resistant solutions.
From September 2 to 6, 2024, Runxing exhibited its products at the South Africa International Construction, Mining, and Power Equipment Exhibition in Johannesburg, presenting our high-chromium wear solutions to African mining and power generation partners.
In 2023, the Dean of Tangshan University and the Metal Materials and Forming Technology Team visited Runxing. General Manager Li Xiuhua and the engineering team discussed ways to optimize hardfacing alloy structures and improve research-to-production efficiency.
Since 2019, Tangshan Runxing Machinery has been an authorized agent for Germany's VAUTID brand, using their welding materials in our premium wear-resistant products to ensure high quality standards.
In April 2023, Runxing Machinery participated in EXPOMIN in Chile, displaying our full range of CCO wear plates and flux-cored hardfacing wires to South American mining companies.
Self-shielded flux-cored wires (FCAW-S) contain core compounds that generate their own shielding gas when vaporized by the welding arc, making them suitable for outdoor and windy conditions where external gas bottles are impractical. Gas-shielded flux-cored wires (FCAW-G) require an external supply of shielding gas (typically $CO_2$ or Argon mixtures). FCAW-G wires generally offer higher deposition rates, cleaner weld chemistry, and lower spatter levels, making them ideal for indoor shop fabrication.
CCO wear plates are manufactured by deposit-welding high-chromium, carbon-rich alloys onto a structural steel backing plate. During cooling, the alloy forms primary chromium carbides ($M_7C_3$) with hardness values up to 1500 HV. These hard carbides are suspended in a tough martensitic matrix, allowing the plate to resist sliding abrasion while the backing plate absorbs mechanical shock and structural loads.
Any industry handling bulk solids, abrasive minerals, or high-velocity particulates benefits from hardfacing. Key sectors include Cement (grinding roller and chute linings), Mining (loader buckets and truck beds), Steelmaking (hopper bells and conveyor guides), Thermal Power (coal pulverizers), and Port Logistics (bulk handling bins and reclaimers).
Runxing utilizes Hebei Yuwan International Trade Co., Ltd. to manage our export operations. Each batch undergoes rigorous testing, including ultrasonic plate inspections, hardness testing (HRC/HV), and optical microscopy analysis of carbide distribution. The trade division coordinates documentation and shipping, ensuring customs compliance and on-time delivery.
