Tungsten Carbide Roll Ring

General roll rings series:Co-Ni-Cr was used as the bonding phase,with high wear resistance, corrosion resistance and versatility.

Product Induction

Compared with  steel  rolls,cemented  carbide  roll  rings  have  the  characteristics  of  longer  life time,higher  cost- effectiveness,higher  dimension  precision  and  better  surface  finish  owning  to  its  high  hardness,good  wear resistance  and  high  modulus of  elasticity,has,thus  greatly  reduce  labor  intensity  and  improve  productivity.

With the development of China’s iron and steel industry,cemented carbide roll rings and rolls are widely used in the production of a variety of products such as wire rolling,bar rolling,tube rolling and small strip rolling and so  on.
