tungsten carbide ring for rebar rolling mill

Cemented carbide roll rings (known as tungstten carbide roll ring) possesses good thermal conduction property. Compared with other materials, it is much better in terms of heat-resistance and strength. What’s more, its hardness reduces a little under the condition of high temperature. So, the cemented 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 factor, which are prior to wear-resistance. While there is low and impact of the rear stands we shall pay attention to the wear-resistance and thermal fatigue resistance of roll rings.
