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.

Welcome to contact us at any time. It is our responsibility to discuss with you and to work out the solutions for you.

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.

Carbide manufacturing process
The production process for various grades of cemented carbide is basically the same, i. e. Prepare powder burden powder mixing-pressing-sintering-post machining. Only some minor process parameter adjustments need to be done occasionally.

In the course of over 70 years of development and as basic theoretical research goes deeper internationally, carbide industry's equipment and technologies improved significantly. New technologies and equipment emerged in western countries in 1970s have become more and more popular in China's carbide manufacturing industry and are driving the development of carbide industry in China.

Powder mixing operation: Tumbling ball mill is gradually changing to blending ball mill, and roller screen granulation is gradually changing to spray granulation.

Pressing operation: As pressing machines become more precise, precision pressing has become the trend. Other new ways for forming carbide products are also emerged, such as vacuum extrusion and cold ISO-static press, 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.
