Welding Chromium Carbide Overlay Plate Good Corrosion Resistance

Product Specification

Description

CCO overlay wear plates can be fabricated and customized to fit various shapes and sizes, making them suitable for different types of equipment, such as chutes, hoppers, buckets, conveyor systems, and crushers. They can be installed using welding or mechanical fastening methods, depending on the specific requirements and conditions.

Overall, CCO overlay wear plates offer exceptional wear resistance, protecting critical equipment surfaces from abrasion and extending their lifespan. They are a reliable solution for reducing downtime, maintenance costs, and improving productivity in high-wear environments.

When are overlay products the best choice?

There are many abrasive situations where overlay plates are the most suitable material, both from a technical and cost perspective. The following are some examples:

• Sliding and moderate impact wear from hard minerals in small size, such as gravel, slurry, and sand with quartz content.
• Sliding wear from larger rocks or impact where rocks are brittle and easy crushable, such as sandstone, limestone, and coal.
• Sliding wear in a wet environment, such as from slurry and dredging operations
• When processing fine particles that cause erosion.

Even if 95% of an abrasive rock is made up of soft minerals, the remaining 5% can be very hard and contribute to 90% of the wear – thus making overlays the best solution.

Advantages

1, high wear resistance
Carbon content in the chemical composition of the alloy layer of 4 ~ 6%, the chromium content up to 25 ~ 30%, the microstructure of Cr7C3 carbide volume fraction of 45% or more, the macro hardness HRC56-62, the hardness of chromium carbide is HV1400 ~ 1800, higher than the hardness of sand quartz in HV800 ~ 1200.Because the carbide into vertical distribution in the direction of wear, even compared with the same composition and hardness of casting alloy, wear-resisting performance is more than double.

2, good resistance to impact
The ground floor of the wear-resistant composite plate is low carbon steel or low alloy.Ductile material such as stainless steel, and demonstrate the superiority of bimetal, wear-resisting layer of abrasion resistance of medium wear and substrate under medium load, thus has a good resistance to impact.Can withstand conveying system under high head hopper and other impact and abrasion.

3, good heat resistance
Wear-resisting layer is recommended to use under the working condition of 600 ºC or less use, if adding vanadium alloy layer, such as molybdenum alloy, can withstand the high temperature of 800 ºC or less wear and tear.Recommended temperature is as follows: ordinary carbon steel substrate recommended is not higher than 380 ºC condition of use;Low alloy heat-resistant steel plate (15 crmo, 12 cr1mov, etc.) recommended base plate is not higher than 540 ºC condition of use;Heat resistant stainless steel substrates recommend used at not higher than 800 ºC condition.

4, good corrosion resistance, wear resistance of composite steel plate containing high percentage of chromium metal alloy layer, so have ability to rust and corrosion.Used for coal cylinder and hopper, etc can be done to prevent caking coal.

Application of Chromium Carbide Overlay Plate

Chromium Carbide Overlay (CCO) plates find application in various industries and equipment that experience high levels of wear. Some common applications of CCO plates include:

• Mining: CCO plates are widely used in mining operations for equipment such as buckets, truck bed liners, conveyor chutes, and screens. They provide excellent wear resistance against abrasion caused by rocks, minerals, and ore.
• Cement: In the cement industry, CCO plates are used in equipment like hoppers, cyclones, and fan blades, which are subjected to abrasive materials like limestone, clay, and cement clinker.
• Power Generation: CCO plates are employed in power plants for applications such as coal chutes, pulverizer systems, and ash handling equipment. They protect against the abrasive effects of coal, ash, and other combustion byproducts.
• Steel Production: Equipment in steel mills, such as slag chutes, coke bins, and furnace components, benefit from the wear resistance provided by CCO plates. They withstand the impact and abrasion caused by the handling and processing of raw materials and molten metal.
• Construction and Earthmoving: CCO plates are used in construction and earthmoving equipment like excavator buckets, bulldozer blades, and crusher liners. They protect against wear caused by rocks, gravel, and abrasive soils.
• Recycling and Waste Management: CCO plates are utilized in recycling and waste management facilities for applications such as shredder blades, conveyor systems, and sorting equipment. They provide protection against wear caused by processing various materials.
• Pulp and Paper: Equipment in the pulp and paper industry, including chip conveyors, debarking drums, and pulp digester components, can benefit from the wear resistance of CCO plates.
• Dredging: CCO plates are used in dredging operations for equipment like dredge buckets, pump casings, and cutter heads. They offer protection against abrasion caused by sand, gravel, and other sediments.
