Modern global heavy industries—including mining, bulk material handling, cement manufacturing, and steel production—sustain multi-million dollar losses annually due to mechanical abrasion and structural degradation. Component failure caused by erosion, adhesion, and impact directly reduces plant availability, forces unscheduled outages, and increases operational expenses (OPEX). To mitigate these failures, structural engineers rely heavily on specialized composite materials such as Chromium Carbide Overlay (CCO) plates.
The global demand for high-performance ODM steel plates has surged as industrial processes become more intense and continuous. In the past, heavy industry relied on basic hardened steels (such as quench-and-tempered steels like AR400 or AR500). However, modern tribology demands superior microstructures. Dual-metal composite plates—consisting of a ductile carbon steel backing (e.g., Q235B or ASTM A36) clad with a high-carbon, high-chromium deposit—deliver a hybrid structure: outstanding toughness to prevent cracking under impact, combined with extreme superficial hardness (ranging from 58 to 62 HRC) to withstand severe sliding abrasion.
As developing countries expand their urban infrastructure and mining centers in regions like Central Asia, South America, and Africa accelerate production, sourcing customizable wear-resistant solutions has become critical. The transition from OEM standard sizes to bespoke ODM (Original Design Manufacturer) profiles is the key driver for modern maintenance efficiency. Engineering departments require pre-cut, pre-curved, and pre-drilled wear liners that can be directly bolted or welded into place during short maintenance windows, dramatically reducing downtime and labor costs.
From a metallurgical perspective, the exceptional performance of Chromium Carbide Overlay (CCO) steel plates is derived from the solid solution chemistry of the clad deposit. The overlay process precipitates primary chromium carbides of the M7C3 type within a tough austenitic eutectic matrix. These primary carbides exhibit a microscopic hardness of up to 1500–2000 HV, providing a barrier against sharp abrasive particles, while the surrounding matrix supports the carbides and absorbs impact forces.
Runxing Machinery is at the forefront of wear-protection engineering. Below is the technical progression path guiding our current production standards and future material developments:
Relying on through-hardened manganese and alloyed steels. Fast wear-out rates in high-stress grinding applications, requiring frequent replacements and leading to high downtime costs.
Introduction of open-arc and submerged-arc cladding on mild steel backing. Deposition of 30-45% chromium carbide overlays, providing a 4-fold increase in service life compared to traditional steel plates.
Our current standard. Utilizing 10.2-inch CNC touch-screen system controls to program uniform swing welding. Multiple welding guns work simultaneously to ensure highly consistent dilution rates and zero defects.
The next generation. Incorporating micro-additions of Niobium (Nb), Boron (B), Titanium (Ti), and Tungsten (W) to refine carbide size, improving resistance to cracking and extreme temperatures (up to 750°C).
Different operating environments present distinct wear mechanisms. While mining operations suffer from a combination of severe gouging impact and abrasion, cement plants face high-temperature erosion from fine dust. We design specialized, target-oriented wear solutions for various sectors globally:
For separator guides, chute liners, cyclone cones, and vertical mill housing components. Runxing CCO plates prevent premature wear caused by high-velocity dry cement particles, ensuring continuous kiln operation.
Designed to withstand the continuous slide of hard ore, granite, and coal. Our wear plates are custom-engineered for truck beds, shovel buckets, and transfer hopper liners, reducing maintenance cycles by up to 60%.
Steel mill applications involve extreme temperatures and chemical corrosion. We supply custom blast furnace charging chutes, coke guide plates, and sinter screen plates capable of maintaining hardness in harsh conditions.
Protection for pulverizer housings, coal pipe bends, coal feeder hoppers, and exhauster fan blades. Minimizes abrasive wear from high-velocity pulverized coal streams and maintains optimal airflow.
Protects high-throughput stacker-reclaimers, grab buckets, hopper silos, and conveyor transfer chutes. Ensures port equipment handles abrasive iron ore, coal, and fertilizer with minimal downtime.
High-purity alumina ceramics sintered at extreme temperatures. Ideal for wet, chemical, or extremely fine abrasive environments where metal contamination must be avoided.
