As a leading manufacturer with a strong foundation since 2017, Wuxi Yansheng Technology Co., Ltd. specializes in providing high-performance wear solutions for demanding industrial applications. Our CCO Wear-Resistant Plate is engineered specifically to combat the severe abrasion encountered in mining screw conveyors and to protect critical components like fan blades. By integrating advanced Chromium Carbide Overlay technology onto a robust steel base, we deliver a product that dramatically reduces downtime, lowers maintenance costs, and enhances the overall productivity and safety of your operations. Trust in our expertise and extensive export experience to supply a reliable component that stands up to the toughest conditions.
The core of our product's performance lies in the Chromium Carbide Overlay (CCO) technology. This process involves depositing a layer of extremely hard chromium carbides onto a ductile steel substrate, creating a composite material that combines superior surface hardness with the toughness of the base metal. This unique structure is key to its exceptional wear resistance.
Key Features and Technical Advantages:
Exceptional Abrasion Resistance: The high-volume fraction of hard chromium carbides provides a surface highly resistant to sliding, scratching, and gouging abrasion, which is prevalent in material handling.
High Impact Resistance: Unlike purely brittle hard materials, the tough steel backing absorbs impact forces, preventing cracking and spalling under heavy loads.
Corrosion & Oxidation Resistance: The chromium-rich overlay offers good resistance to mild corrosive environments and oxidation at elevated temperatures.
Customizable Design: We can manufacture plates tailored to your specific equipment dimensions, hole patterns for bolting, and required thickness profiles.
Easy Installation: The plates can be easily integrated into existing systems through welding or bolting, minimizing retrofit complexity.
Primary Applications and Benefits:
Mining Screw Conveyors: Used as liner plates in troughs, flights, and hangers. It protects the conveyor structure from the abrasive action of ores, coal, and aggregates, leading to:
Extended conveyor life by 3-5 times compared to standard steel.
Reduced maintenance frequency and associated labor costs.
Improved material flow efficiency by preventing material buildup on worn surfaces.
Fan Blade Protection: Applied as leading-edge wear strips or cladding on industrial fan blades handling particulate-laden air (e.g., in power plants, cement plants). Benefits include:
Preservation of fan aerodynamic efficiency and balance.
Prevention of premature blade failure due to erosion.
Reduction in unplanned shutdowns for blade repair or replacement.
Other Applications: Also suitable for chute liners, hopper skirts, classifier shoes, and any component subject to severe sliding abrasion.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of CCO plate over standard AR (Abrasion Resistant) steel plate?
A1: While AR steel offers good hardness, CCO plate features a metallurgically bonded overlay of much harder chromium carbides. This results in significantly higher abrasion resistance, often providing 3-5 times longer service life in severe sliding wear applications, making it more cost-effective over the long term.
Q2: Can your CCO plates be welded onto existing equipment?
A2: Yes, they can be welded. We recommend using specific welding procedures to avoid cracking the hard overlay. Our technical team can provide welding guidelines. Alternatively, the plates can be supplied with bolt holes for mechanical attachment, which is often simpler.
Q3: How do I determine the appropriate thickness for my application?
A3: The required thickness depends on the abrasiveness of the material, impact forces, and the expected service life. We typically advise based on your operating conditions. Common thicknesses for conveyor liners range from 10-20 mm, while fan blade protection may use thinner strips (6-12 mm).
Q4: Are these plates resistant to corrosion as well as abrasion?
A4: The chromium carbide overlay provides good resistance to mild corrosion and oxidation. However, for applications involving strong acids or alkalis, we recommend discussing the environment with our engineers, as additional material selection considerations may be needed.
Q5: What is your typical lead time for custom-sized plates?
A5: Lead times vary based on order quantity, complexity, and current production schedule. For standard-sized plates or common shapes, delivery can often be arranged within a few weeks. We provide estimated timelines upon order confirmation.
Q6: Do you provide installation support or on-site guidance?
A6: We primarily supply the product along with detailed installation instructions (welding parameters, bolt torque specs). For complex projects, technical consultation is available. On-site support can be arranged subject to discussion and agreement.
Q7: Can the plates be cut or machined on-site if dimensions need adjustment?
A7: On-site machining is challenging due to the extreme hardness of the overlay, which requires specialized tools like carbide-tipped saws or grinding. We highly recommend providing precise dimensions so we can supply ready-to-install plates, which is more efficient and avoids tooling issues.
Q8: What quality control measures are in place during manufacturing?
A8: Our production follows strict quality protocols under our ISO9001-certified system. Key checks include base material verification, overlay hardness testing, dimensional accuracy inspection, and visual examination for defects to ensure every plate meets performance standards.
