Explore Specifications →For decades, heavy industrial operations in cement mills, mining operations, and steel furnaces struggled with catastrophic abrasive wear. The transition from manual stick welding processes to automated wire welding machines has revolutionized modern industrial surfacing.
At the center of this revolution is the optimization of chromium carbide alloys. Modern wear protection relies heavily on **Chromium Carbide Overlays (CCO)** and **Self-shielded Flux-Cored Wires** designed to run at high deposition rates. The automated wire welding machine represents a significant leap forward, replacing inconsistent manual deposits with uniform, high-density carbide matrices.
"By automating the surfacing mechanism, factories can control dilution rates, grain structure orientation, and carbide dispersion, resulting in a wear lifespan up to 10 times longer than standard carbon steels."
The metallurgical structure of a wear plate or rebuilt grinding roller determines its performance. Using advanced welding wire under precise temperature control ensures the formation of primary M7C3 chromium carbides. These carbides exhibit a hardness of over 1500 HV, dispersed in a tough, austenitic matrix that prevents cracking under moderate impact loads.
Procuring heavy-duty wear components and automated wire welding systems demands strict compliance, reliable delivery channels, and direct factory verification.
Founded in 2010, **Tangshan Runxing Machinery Co., Ltd.** operates a state-of-the-art facility in Tangshan, Hebei Province. Runxing focuses exclusively on metallurgical R&D, advanced design, and production of chromium carbide overlay (CCO) wear plates, flux-cored welding wires, and automatic hardfacing machines.
To provide global partners with risk-free logistics and seamless capital processing, all export business is handled by **Hebei Yuwan International Trade Co., Ltd.** This dedicated entity manages international trade procedures, including customs declarations, complex shipment documentation, banking payments, and local compliance verification. This allows Runxing’s engineering teams to focus entirely on maintaining stable material performance and on-time manufacturing schedules.

Our CCO wear plates contain high concentrations of chromium carbide (typically 20% to 30% chromium and 3.5% to 5.5% carbon) deposited on a structural steel backing. The resulting microstructure exhibits primary M7C3 carbides with a hardness between 58 and 62 HRC, corresponding to DIN 8555 standards.
The four-gun configuration allows the automated welding system to deposit wear materials across multiple areas simultaneously or independently. It features a 10.2-inch touchscreen numerical control system that maintains stable swing profiles, reducing manpower requirements while ensuring a consistent, low-dilution weld bead.
To optimize production workflows, Runxing Machinery focuses entirely on R&D, fabrication, and quality inspections. All export transactions, customs documentation, shipping arrangements, and payments are managed by Hebei Yuwan International Trade Co., Ltd.
Yes. While high-chromium alloys are primarily optimized for sliding abrasion, the addition of specific micro-alloying elements like niobium and boron, combined with proper deposition control, improves the resistance of the matrix to moderate mechanical impacts.
Our repair services cater to grinding rolls used in vertical mills, coal pulverizers, cement roller presses, steel continuous casting machines, and mineral crushing systems. Rebuilding worn roll surfaces directly extends their service lifespans and reduces operating overhead.
