Cemented Tungsten Carbide Rings Good Wear Resistance For Rolling Mills
Description of the tungsten carbide roll
Carbide rolls are widely used in metal forming, especially in hot rolling industry mainly for intermediate and last finishing stands to ensuring superior surface finish and dimensional stability of processed metal products. Rolls are also commonly used for wire flattening, de-scaling and straightening applications.
