What is the performance of wear-resistant cladding plate?
Performance Analysis
Chemical Composition
The wear resistance of cladding composite plates is achieved through a low-carbon steel substrate layered with a chromium carbide alloy. Special elements enhance carbide formation, with carbides constituting over 50% of the metallographic structure.
Hardness
The surface hardness depends on the wear-resistant layer thickness, adjustable within HRC56-65. Chromium carbide microhardness reaches HV1800, ensuring durability in various conditions.
Flatness and Thickness
Flatness error remains within ±3mm/m, ensuring stable installation and usage. The wear-resistant layer maintains uniform thickness with a positive tolerance of 0-0.5mm, extending its lifespan.
Dimensions
Width
Maximum width reaches 2200mm, facilitating large equipment production while minimizing cutting, splicing, and costs.
Length
Maximum length of 10,000mm suits large-scale projects like mining machinery, crushers, and mill liners, enhancing durability and reducing maintenance costs.
Conventional Plate Thickness Specifications
Light and Thin
Options such as 3+3, 4+4, and 5+5 are suitable for low-wear environments.
Heavy-Duty
Options like 16+6, 18+8, and 20+10 suit high-temperature and high-pressure applications, such as metallurgical rollers and coal conveyor belts.
Teda provides a variety of plate thicknesses to meet diverse industrial needs.
Thickness Specifications by Plate Type
High Chromium Wear-Resistant Plate
With a wear layer up to 32mm thick, carbon content between 3.5%-5.5%, and chromium at 27%-40%, this plate forms over 50% Cr₇C₃ carbides, offering extreme hardness. Common substrate thickness is 6-10mm, balancing strength and wear resistance.
Impact-Resistant Plate
Wear layer thickness ranges from 20-40mm, absorbing high-speed impacts in stone-crushing production. The substrate, typically 8-12mm, supports impact dispersion and stability.
High-Temperature Wear-Resistant Plate
Designed for extreme heat, the wear layer ranges from 25-50mm. Suitable for furnace tuyeres and slag outlets, it withstands molten iron, slag, and thermal stress. The substrate, 10-15mm thick, resists deformation under high temperatures.
Crack-Free Wear-Resistant Composite Plate
With a 15-30mm wear-resistant layer, this plate ensures durability in steel rolling applications, preventing cracks in precision components. The base plate, 6-9mm thick, provides structural stability.
Special Element Wear-Resistant Plate
Wear layer thickness varies between 10-40mm, with elements like Mo, Nb, Ni, W, and Y added for corrosion and wear resistance in chemical processing. The base plate, typically 5-10mm, ensures long-term equipment stability.
Applications and Advantages
Wear-resistant cladding composite plates are widely used in industries such as mining, cement production, power plants, and metallurgy. Their benefits include superior wear resistance, easy processing, and customization based on user requirements, reducing downtime and operational costs.
