Tungsten Carbide Rings
It is widely applied in the production of bar, high wire and deformed steel bar. It is usually used at the front stand of finishing mill, the last stand of finishing mill and the pre-finishing mill.
Cemented carbide roll rings (also know as tungsten carbide roll ring )possesses good thermal conduction property.Compared with other material,it is much better in terms of heat-resistance,wear-resistance and strength.What's more ,its hardness reduce a little under the condition of high temperature.So the cement ed 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 deformed steel bar.
At present,the finishing mill is generally composed of 8-10 stands.Because of the big size of fracture surface of rolled part,the collar on the front stands of finishing mill may resist heavy duty and strong impact.Thus,the high hardness and good thermal fatigue resistance are the primary factors,which are prior to wear-resistance.While there is low load and impact for the rear stands,we shall pay more attention to the wear-resistance and thermal fatigue resistance of roll rings.
