Provide tungsten carbide roll rings for bar mill plant

As a loyal partner of steel mill customers. We do our best to provide users with more services and Chinese products. Just in early September, FV Bearing Company helped a batch of valuable tungsten carbide roll rings in a famous Türkiye steel mill plant. All this comes from the steel plant's trust in FV. FV provides high-quality rolling mill bearings to users. Users believe that FV bearings are experts in the metallurgy industry. And FV application engineers understand the performance requirements of cemented carbide and superhard materials. FV Bearing is willing to provide more accessories procurement and quality control services to steel mills around the world.

Brief introduction to cemented carbide roll rings

Cemented carbide roll rings (also known as tungsten carbide roll ring) possesses good thermal conduction property. Compared with other materials, it is much better in terms of heat-resistance, wear-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.

As far as the material for our products, there are two series as Wc-Co and Wc-Co-Ni-Cr which possess the good comprehensive mechanical properties. The bending strength and impact toughness reach 2200 Mpa and ( 4-6 ) x106J/m2 respectively.

Its hardness and wear resistance come from tungsten carbide (Wc) while the toughness and strength depend on the binding agent (Co-Ni-Cr).

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 ther-mal 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.

This manual describes the grades and properties of our cemented carbide roll rings in detail so that you can make the correct choice.
