Tungsten Carbide Roll Rings
Cemented carbide roll rings(also known as tungsten carbide roll rings) possesses good thermal conduction property.
Compared with other materials, it is much better in terms of heat-resistance, wear-resistance and strength. What's more, its hardness reduces a little under the condition of high temperature. So the cemented carbide roll rings is invented with the appearance of high speed wire rod mill. With the development and improvement. It is widely applied in the production of high speed wire, bar and defomed steel bar.
Specifications:
Material: Wc-Co and Wc-Co-Ni-Cr
High quality tungsten carbide roll rings for rolling mill are widely used as seal faces with resistant-wearing, high fracturing strength, high thermal conductivity, small thermal expansion coefficient. It is the best material to resist heat and fracture in all hard face materials.
Property:
1. High hardness & good wear resistance. Normal hardness reaches
HRA 78-89, under temperature 600 ,beyond hardness of high speed steel
2. High elasticity modulus
3. High mechanical strength, compressive strength is up to 6000MN/M2
4. High density
5. Good thermal conductivity
6. Good corrosion& oxidation resistance
