Description of product
Carbide roller rings
High quality tungsten carbide roll / rollers for rolling mill are widely used as seal faces with resistant-wearing, high fracturing strength, high thermal conductivity, small heat expansion co-efficient. It is the best material to resist heat and fracture in all hard face materials.
Service is to be rendered for the design, grooving machining and rib machining of composite cemented carbide roll rings.
Various compatible tools can be provided for machining composite cemented carbide roll rings.
