| Characteristics |
Common chromium carbide wear plate, suited for use in general wear applications involving low to medium impact |
| Composition: |
The wear-resistant composite steel plate is a layer or multiple layers of wear-resistant alloy containing a large number of chromium carbide hard particles deposited on the medium and low carbon steel substrate, and some special elements are added to form carbides with special effects. |
| microstructure: |
The volume fraction of Cr 7C3 carbide in the metallographic structure of the wear-resistant layer reaches more than 50%. |
| Hardness: |
According to the thickness of the wear-resistant layer and the application, the surface hardness of the wear-resistant alloy ranges from HRC56-65, and the micro-hardness of chromium carbide is up to HV1800. |
| Abrasion resistance: |
Laboratory results show that the wear resistance of high-chromium surfacing wear-resistant composite steel is 20 times that of low-carbon steel and 8 times that of heat-treated wear-resistant steel. ASTM-G65A dry sand wear test surface wear and 75% deep wear test The data shows that it has high wear resistance. |
| Flatness: |
The flatness is controlled at soil 3mn/m. |
| Thickness error: |
The thickness of the wear-resistant layer is uniform, and the thickness tolerance is 0-0. 5mm. |

Processing of Chromium carbide cover plate:
Chromium carbide cover plate can be tailor-welded into various structural parts or parts through the welding of base layer steel plates. Use a plasma cutting gun to drill holes in the wear-resistant composite steel plate and fix it with bolts set on the protected equipment for easy maintenance and replacement.Chromium carbide cover plate have high hardness and require plasma cutting. According to the different size and shape requirements of users, we can provide wear-resistant plates with corresponding sizes and shapes.
Users can also purchase the whole wear plate and cut it by themselves. Bending processing varies according to the hardness and thickness of the wear-resistant steel plate. The minimum bending diameter is usually ≥350mm, which can be made into flat plates, arc plates, cone plates, and cylinders. When the reel is processed, the bending direction should be as consistent as the welding bead direction, especially for small diameter bending, which needs to be bent according to the requirements of the supplier!
Application range of Chromium carbide cover plate
Application scope of port conveying equipment: Grabs, hoppers, chutes and other parts in bulk cargo handling systems such as iron ore and coal are subject to severe abrasion. Welding and wear-resistant composite steel plates are used in the easy-to-wear parts to extend these wear parts. It is very important to reduce the downtime of loading and unloading machinery for maintenance.
Applications in the mining industry: truck cargo tank lining, hopper lining, conveying chute lining, crusher parts, cover plates, wear bars and wear plates, electric shovel, shovel, slagging machine, loading Machine bucket, bulldozer bucket, dragline.
Application scope in the power plant industry: in fan blades, burner pipelines, lining of conveying troughs and hoppers, crusher parts, coal mill parts, ash outlet pipes, air handling systems and conveyors, chutes, pipe trough systems, coal feeding Trough, feed pipe trough, grab hopper trough, coal feed trough pipe, separator cone. Coal feed hopper, raw coal feed pipe trough, fuel conveying pipe, exhaust fan blade, coal mill cylinder liner, coal mill roller head liner, coal drop tube wear-resistant elbow, coal mill inner wall liner, Baffle plate, rotating air ring, coal falling trough, wear-resistant short pipe, burner combustion chamber, burner elbow,
The scope of application in the steel plant is: on-line surfacing repair of broken rolls in sintering plants, roll surfacing welding wires, silo liners, sliding slopes, screens, blast boiler bell covers, feed cars, blast boiler reinforced steel plates, and sintering Feeding barrels, pipes, distribution plates.
