Tungsten Carbide Roll Ring as the characters of high wear resistance, high corrosion resistance and good compressive properties. It's widely used in petrochemical industries and other industries which call for high properties of the mechanical sealing rings or prats.
We can offer roll rings with different dimensions and can also produce roll according to your special requirements, like making groove before the sintering which can shorten the delivery time effectively and leave out the expensive and time-consuming machining process for you.
We make stress elimination for each product.
The working procedures: Fully communicate with the customers to understand their different demands. So our engineers can give you advice when you choose the grade, determine the data of grinding and cutting, use roll and trace the roll performance.
We will offer you the most suitable roll rings in conformity with your mill and operation conditions.
Our corporation's vision is "To be the symbol of carbide roll rings and the most reliable supplier for non-standard carbide clients. "
Our material covers: WC-Co alloy, WC-Ni alloy, WC-Ni/Co alloy, WC-TiC-Ni/Cr alloy etc.
Sintering operation: The earliest method was to use hydrogen sintering furnace, and then, vacuum sintering and hot ISO-static press furnace were adopted. The most revolutionary change was the emergence of sinter-HIP furnace, which made it possible to produce 100% dense carbide products.
