Engineered to withstand the extreme abrasion, high dust conditions, and operational thermal cycles characteristic of Iraq's cement, mining, and oil fields.
A comprehensive technical analysis of tribological issues, material selection, and high-efficiency supply chain integration for Iraqi cement, mining, and power generation industries.
Industrial machinery in Iraq faces dual wear forces: high-stress grinding abrasion from regional mineral deposits and atmospheric particulate abrasion caused by dust storms containing sharp quartz silica particles. Typical industrial sectors in Basra, Karbala, and Sulaymaniyah experience premature failure of hopper liners, chute systems, and fan blades, making standardized mild steel inadequate.
By metallurgical deposition of a hypereutectic alloy onto structural steel backing, CCO plates present a surface containing up to 30-45% primary M7C3 carbides. These carbides, reaching a hardness of 1500 HV, effectively block penetrating abrasive grains. This ensures Iraqi cement processing lines can achieve continuous operations without catastrophic failures.
Industrial infrastructure in Iraq is undergoing rapid modernization and capacity expansion. From the major cement manufacturing hubs in Sulaymaniyah, Bazian, and Karbala, to the intensive oil and gas extractions in the southern Basra governorate, mechanical components are subjected to relentless abrasive forces. In Iraq, materials handling equipment commonly handles raw limestone, gypsum, clinker, and oil-silt slurry. The combination of ambient summer temperatures reaching 50°C and mechanical friction results in elevated operating temperatures for conveyor chutes, hoppers, cyclones, and pipelines.
Standard structural steels (like Q235 or Q345) and even basic quenched-and-tempered plates (such as standard AR400 or AR500 grades) rapidly lose structural stability under high-stress grinding abrasion. To address this, Runxing Machinery introduces CCO (Chromium Carbide Overlay) wear plates. These composite materials utilize a ductile structural steel backing (which absorbs impact and permits welding and structural installation) and a high-alloy, wear-resistant overlay containing primary chromium carbides (M7C3). Under severe abrasion, these carbides act as a shield, extending the service life of equipment by up to 5 to 10 times compared to traditional steel plates.
The performance of a wear plate relies on its microstructural characteristics. Our manufacturing process uses automated open-arc weld overlay cladding technology. Our metallurgical engineering maintains a strict chemical composition ratio:
As a major manufacturer located in Tangshan, China's steel industrial hub, Tangshan Runxing Machinery Co., Ltd. offers a reliable supply chain. Our manufacturing capability allows us to produce standard and custom CCO plates with short lead times. To facilitate trade, all global exports are managed by Hebei Yuwan International Trade Co., Ltd.
This partnership offers Iraqi buyers a seamless supply chain. While our manufacturing facility focuses on CNC precision cutting, automatic weld overlaying, and quality testing, Hebei Yuwan manages ocean logistics, document preparation (including Certificates of Origin and compliance papers), and shipping coordination to major Iraqi entry points like the Port of Umm Qasr or directly to project sites in Baghdad, Erbil, and Basra.
Our diversified product ecosystem meets the demands of modern industrial operations.

Real-world industrial wear protection solutions deployed to extend equipment life in high-stress operational environments.
Equipment availability is critical for cement production lines in Karbala and Sulaymaniyah. Deploying CCO plates in raw meal hoppers and clinker chutes protects machinery surfaces from abrasive clinker dust, helping to extend scheduled maintenance intervals.
For quarrying and mineral extraction operations in northern Iraq, our composite wear liners are designed to handle impact and abrasion during bulk handling and sorting, reducing downtime for high-wear chutes.
Steel plants in Erbil operate under severe mechanical stresses and high-temperature profiles. Our hardfaced guide plates and scraper blades are designed to withstand thermal cycles and abrasive dust.
Thermal power plants utilize CCO protection for coal hopper linings, pulverizer discharge chutes, and fan blades to resist abrasion from fine fuel particles.
Dry bulk terminals at Iraqi ports process minerals, grains, and fertilizers. Installing CCO liners in crane grab buckets and receiving hoppers protects equipment surfaces from abrasion during cargo transfer.
For high-velocity sliding abrasion without major impact, we provide high-purity alumina ceramic liners sintered at high temperatures. These offer a low-friction option for dry powder handling systems.
We work to adapt our wear liner configurations to changing industrial demands. New application testing is continuously under review.
We design custom wear liners based on user drawings, developing solutions tailored to specific geometry and flow patterns.
