As a hard material, The Tungsten carbide roll ring is composed of a hard phase (tungsten carbide).
In combination with metals (usually cobalt, nickel) and trace rare metal elements.
Its performance depends on the content of the binding metal and the size of the tungsten carbide particles.
TC rings have good turning performance, without the need for a special lathe, the existing lathe can roll the ring turning.
When turning, the tool head can be made of high-hardness carbide tool material.
Compared with steel rolls, this significantly reduces labor intensity and improves productivity.
TC rings have excellent material combinations and reasonable production processes, and have excellent thermal fatigue resistance and corrosion resistance; TC rings have high strength, high toughness, high thermal conductivity, high bending strength, low wear, and good thermal hardness. The service life is much longer than that of ordinary roller rings.
Cemented carbide roll rings, also known as tungsten carbide roll rings, are recognized for their outstanding thermal conductivity. When compared to other materials, they excel in heat resistance, wear resistance, and strength. Although their hardness slightly decreases at elevated temperatures, TC rings continue to offer remarkable durability. The development of cemented carbide roll rings was driven by the demand for advanced materials in high-speed wire rod mills.With the development and improvement, TC rings are widely applied in the production of high-speed wire, bar, and deformed steel bar.
