tungsten carbide roller Parameters Table

Product Details

Cemented carbide roll rings (also known as tungsten carbide roll rings) 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 a 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 good compre­hensive mechanical property. The bending strength and impact toughness reach 2400 Mpa and (4-6)x106 J/m² respectively. Its hardness and wear resistance comes from tungsten carbide (Wc) while the toughness and strength depend on the binding agent (Co-Ni-Cr).

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