Cemented carbide sealing ring is made of tungsten carbide powder as raw material, adding an appropriate amount of cobalt powder or nickel powder as binder, pressing into a ring through a certain die and sintering in a vacuum furnace or hydrogen reduction furnace. It is a common production and processing product in cemented carbide manufacturers. Because of its high hardness, good anti-corrosion performance and strong sealing, it is widely used in petrochemical and other sealing industries.
Cemented carbide sealing ring is composed of hard metal. It is stronger than titanium ring and more durable than gold ring. It's also hard, but it's not scratch proof. Cemented carbide sealing rings can only be scratched by diamonds or corundum products containing minerals.
Cemented carbide sealing ring has the characteristics of wear resistance and corrosion resistance. It is widely used in mechanical seals in petroleum, chemical and other fields. Its product types include flat ring, table ring and other special-shaped rings. Let's see what features it has:
1. After fine grinding, the appearance meets the accuracy requirements, its size and tolerance are very small, and the sealing performance is very superior;
2. Corrosion resistant rare elements are added into the process formula to make the sealing performance more lasting;
3. It is made of high strength and high hardness cemented carbide, which is not deformed and more compression resistant;
4. The material of the sealing ring must have sufficient strength, hardness, wear resistance, corrosion resistance and impact toughness.
At the same time, cemented carbide sealing ring also needs to have good machining type and reasonable economy. Among them, wear resistance, corrosion resistance and hot crack resistance are the most important requirements. As we know, cemented carbide has a series of excellent properties, such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance. In particular, its high hardness and wear resistance remain basically unchanged even at 500 ℃ and still have high hardness at 1000 ℃. Therefore, cemented carbide sealing ring has become the most widely used product in mechanical seals.
As the most widely used mechanical seal product, its demand is also increasing with the development of economy and the improvement of technology. Cemented carbide sealing rings can be divided into many grades according to different bonding phases. According to Sidi's many years of production experience, users use more cemented carbide sealing rings with grades of 6% Ni and 6% Co. Its brand cemented carbide sealing ring has higher hardness and wear resistance, and superior anti-corrosion performance.
We can provide customers with customization of cemented carbide sealing rings of various specifications and models. Special production customization can be carried out according to users' drawings. The produced sealing rings meet the following requirements: small concentricity and high precision; High flatness of end face and uniform stress; Long service life; Stable quality and performance.
