Long-Life, Wear-Resistant Solid Tungsten Carbide Rolls

In modern industry, industrial sectors increasingly pursue ultimate efficiency and cost control. The durability of rolling mills directly relates to production line stability and profitability. Our custom solid tungsten carbide rolls, with their exceptional wear-resistant characteristics and robust integrated structure, provide you with long-life tungsten carbide roll solutions. While the initial roll cost is higher, for high-volume production, it effectively reduces replacement costs and time costs.

Material Composition

The roll body utilizes high-hardness tungsten carbide particles with tough cobalt-based bonding phase, formed through advanced low-pressure sintering process into a one-piece structure, creating a dense, defect-free solid construction. This establishes the foundation for ultra-long life from the material level. Its hardness reaches above HRA90, with wear resistance far exceeding traditional alloy steel rolls by dozens of times. Different carbide content and grades can be used according to customer requirements.

Core Performance

The product’s core strength lies in its ultimate wear resistance performance and ultra-long service life. Field testing demonstrates that under equivalent working conditions, its wear resistance is 8 to 10 times greater than high-chromium steel rolls, with significantly extended service life that effectively reduces shutdown replacement frequency and ensures continuous production. The one-piece solid integral structure eliminates cracking and spalling risks, providing stronger rigidity and higher safety. Load capacity and stability significantly surpass composite roll rings.

Application Industries

Widely applied in high-speed wire rod finishing mill groups, bar and rebar finishing mill stands, non-ferrous metal foil and strip rolling, and other fields with extremely high requirements for wear resistance and dimensional accuracy. It serves as the core component ensuring product surface quality and tolerance consistency.

Competitive Advantages

Compared to traditional rolls, solid tungsten carbide rolls not only offer longer life and lower wear, but also maintain precise roll gaps and groove profiles over time, ensuring stable rolled material dimensions. The resulting reduction in roll changes, improved yield rates, and decreased downtime losses create significant economic benefits for users.

Custom Services

We support customization of various tungsten carbide roll ring specifications and precision groove profiles, and can select different tungsten carbide material contents based on different rolling materials and process conditions, ensuring each roll delivers optimal performance in its specific application. Processing accuracy ±0.002mm, concentricity ±0.003mm, with mirror grinding and polishing processing.
