Tungsten Carbide Roll Rings
High qualitytungsten carbide roll rings for rolling mill are widely used as seal faces withresistant-wearing, high fracturing strength, high thermal conductivity, smallthermal expansion coefficient. It is the best material to resist heat andfracture in all hard face materials.
1. Highhardness & good wear resistance. Normal hardness reaches HRA 78-89, undertemperature 600 ,beyond hardness of high speed steel
2. Highelasticity modulus
3. Highmechanical strength, compressive strength is up to 6000MN/M2
5. Goodthermal conductivity
6. Goodcorrosion& oxidation resistance
