Modern heavy industries—ranging from modern mineral processing, extraction, deep mining, and coal-fired thermal generation to civil construction—are operating under increasingly severe mechanical stresses. Standard structural carbon steels can no longer endure the continuous abrasive, erosive, and high-impact conditions typical of these applications. Consequently, critical equipment suffers premature wear-induced breakdown, resulting in catastrophic operational losses, unscheduled system shutdowns, and highly inefficient maintenance costs.
To address these challenges, material sciences and engineering projects have shifted focus toward customized protective overlay methodologies. Central to this technological breakthrough is the deployment of optimized Flux Cored Wires and high-performance Chromium Carbide Overlay (CCO) plates. Original Design Manufacturer (ODM) partners serve a pivotal role in this ecosystem by customizing weld chemistry properties to counter unique operational realities. Rather than using off-the-shelf welding consumables, modern buyers seek high-specification alloy elements that match local structural stresses, extreme heat profiles, and chemical erosion factors.
Deploying specialized flux cored materials minimizes thermal distortion during the hardfacing overlay process, ensuring structural stability across heavy parts.
Custom ODM solutions permit fine control of Chromium, Niobium, Carbon, and Boron fractions to target specific degradation mechanisms.
Our solutions extend component service life by up to 300% compared to conventional heat-treated alloy steels, significantly reducing operational downtime.
Industrial wear is never uniform. Different manufacturing, transport, and thermal generation sectors face distinct challenges. Understanding these failure modes allows us to engineer materials that withstand specific operational realities.
The key issue for any cement plant lies in the availability of critical equipment. The key to equipment availability is wear resistance, and the performance of wear-resistant products determines the operating time of critical equipment. In cement manufacturing, processing raw limestone, silica, and hot clinker exposes equipment to intense friction and heat. Our hardfaced wear liners are designed to protect feed chutes, separator guide vanes, and vertical mill tables from continuous abrasion under elevated operating temperatures.
Mine operators around the globe are seeking to increase productivity, profitability and sustainability. We help our partners achieve these goals by delivering the mining industry's most comprehensive and cost-effective wear solutions. From excavator buckets and hopper boxes to deep chute liners, mining equipment must withstand high stress grinding abrasion alongside severe impact forces. By combining robust backing steels with hard carbide microstructures, we deliver dependable armor against both continuous wear and shock loading.
In the steel industry, the use of equipment is even more brutal, involving raw minerals, high temperatures, corrosion and other working conditions. Sinter plant screens, guide plates, and coke distribution chutes are subjected to continuous abrasion at temperatures exceeding 600°C. Under these conditions, typical carbide alloys can degrade rapidly. Our high-temperature resistant chromium-niobium overlay plates provide the thermal stability needed to prevent soft-phase degradation and sustain high structural performance.
Fossil fuel energy generation facilities face localized, high-velocity particle erosion. Key equipment requires comprehensive wear protection, including fan blades, conveyor chutes, hopper liners, pulverizing crushers, coal mills, dust removal systems, and bulk conveying pipes. Implementing chromium carbide overlays inside pulverizer housings and exhaust conduits ensures steady flow paths and prevents local breakthrough failures.
Ports are mainly to transport various materials, conveying equipment, loading and unloading equipment, as well as yard stacking and picking equipment, is the main force of port operations, and the damage of these equipment directly affects the benefits. Handling hundreds of tons of iron ore, coal, or fertilizers per hour causes severe abrasive wear on reclaimers, stacker buckets, and drop hoppers. Our field-proven overlay plates ensure these high-capacity material handling systems operate reliably without unplanned interruptions.
For applications where metallic alloys are not optimal, wear-resistant alumina ceramics offer an alternative. Made of high purity superfine alumina powder and sintered at high temperatures using optimized formulas, these ceramics provide exceptional hardness and chemical resistance for slurry transport and high-velocity dry particle handling.
Founded in 2010 in Tangshan, Hebei Province—the heartland of Chinese steel production—Tangshan Runxing Machinery Co., Ltd. is a professional manufacturer focused on the R&D, production, and on-site construction of hardfacing wear-resistant metal products. With over a decade of research, the company has developed advanced metal surface hardfacing techniques to produce high-durability alloys.
Our core manufacturing program includes chromium carbide overlay (CCO) wear plates, custom-processed wear liners, wear-resistant pipes and fittings, hardfacing flux-cored welding wires, automatic hardfacing welding machines, and professional roller surfacing repair services. We operate on the business principles of integrity, superior quality, innovation, and sustainable development.
To ensure streamlined service for international buyers, all export logistics, customs clearance, and global transactions are handled by our authorized trading partner, Hebei Yuwan International Trade Co., Ltd. This specialized division manages payment processing, document handling, and global shipping, allowing our manufacturing facility to focus entirely on maintaining quality and on-time delivery.
We believe that sustained research is key to product reliability. In 2023, senior leadership from Tangshan University—including Yuan Shaoqiang (Dean), Li Jing (Vice Dean), and Professor Yang Yuehui (Team Leader of Metal Materials and Forming Technology)—visited our manufacturing plant for collaborative research into advanced crystallization control in high-alloy welds. This academic-industrial partnership helps keep our wear mitigation products at the cutting edge of material science.
Additionally, our products are regularly showcased at major trade exhibitions. Runxing Machinery participated in EXPOMIN 2023 in Santiago, Chile, as well as the Africa 2024 International Construction and Mining Exhibition in Johannesburg, South Africa, demonstrating our commitment to serving global mining and heavy engineering projects.
To achieve high abrasive wear resistance, flux cored wires must form dense distributions of primary chromium carbides (M7C3) within a tough, stable matrix. The standard chemistry of these systems must be carefully balanced to prevent embrittlement while maximizing surface hardness.
Modern R&D focus is moving toward refining carbide grain sizes. When primary chromium carbides are large, they are susceptible to micro-cracking and chipping under impact. Introducing grain-refining elements like Niobium (Nb), Titanium (Ti), and Tungsten (W) creates finer, more evenly dispersed carbides. This improves both the toughness and wear resistance of the weld deposit, enabling hardfaced parts to withstand more severe impacts.
Optimizing the welding material is only half the battle; the application process is equally important. Our high-efficiency automated hardfacing welding machines feature 10.2-inch digital touchscreens and advanced PLC controls. These systems coordinate up to four welding torches simultaneously, adjusting swing patterns and deposition speeds to produce flat, consistent wear overlays with low dilution rates.
