View Details"In heavy industrial processing, material erosion and mechanical abrasion account for up to 70% of premature component failures. Implementing advanced metallurgical bimetallic solutions is not just an equipment upgrade—it is a critical operational strategy to maximize uptime and eliminate unscheduled maintenance cycles."
Heavy industries such as mining, cement production, steel manufacturing, and power generation process billions of tons of abrasive materials annually. In doing so, their chutes, liners, crushers, and transfer pipes are subjected to severe wear mechanisms, specifically two-body and three-body sliding abrasion, high-velocity particle erosion, and mechanical impact. Standard carbon steels fail rapidly under these conditions, leading to frequent shutdowns, loss of throughput, and escalating labor costs.
By utilizing Chromium Carbide Overlay (CCO) wear plates, industrial operators achieve a vital upgrade in surface hardness. CCO composites feature a ductile backing plate (typically Q235B or ASTM A36 structural steel) welded to an extremely hard, alloy-rich overlay. The high concentration of primary chromium carbides (specifically Cr7C3 with micro-hardness exceeding 1500 HV) embedded within a tough eutectic matrix creates a barrier that resists micro-cutting and plowing mechanisms from sharp, hard minerals.
The wear-resistant properties of CCO depend strictly on the chemical formulation of the hardfacing layer and the solidification rate of the weld pool. The primary phase consists of hexagonal M7C3 carbides, which form during the initial stages of solidification. Runxing Machinery utilizes proprietary flux-cored wire formulations containing high carbon (3.5% to 5.5%) and high chromium (25% to 35%) levels to guarantee a minimum density of 35% primary chromium carbides in the microstructure.
The metallurgical bond between the base carbon steel and the wear overlay must have low dilution rates. High dilution from the base metal decreases carbon and chromium concentrations in the overlay, weakening wear resistance. Our advanced automatic hardfacing systems employ controlled heat inputs and sophisticated oscillating weld patterns to keep dilution below 10%, ensuring consistent hardness profiles (ranging from 58 to 65 HRC) from the surface down to the fusion line.
The production of RX®wp 7600 wear plates complies with the stringent DIN 8555 standard, which categorizes hardfacing products according to chemical composition and mechanical stress properties. This guarantees that our bimetallic steel plates deliver stable quality in applications with severe impact and high stress. Our hardfacing wire configurations employ self-shielded open arc technology, eliminating the need for external shielding gas or flux, and ensuring seamless field repairs and rebuilds.
