Tungsten carbide sealing ring is made of tungsten carbide powder as raw material, adding appropriate amount of cobalt powder or nickel powder as binder, pressed into a ring through a certain mold, and sintered in a vacuum furnace or a hydrogen reduction furnace. It is a relatively common production and processing product in cemented carbide manufacturers. Because of its high hardness, good anti-corrosion performance, and strong sealing performance, it is widely used in petrochemical and other sealing industries.
Tungsten carbide seal rings are composed of a hard metal that is stronger than titanium rings and lasts longer than gold rings. It's also tough, but not scratch-resistant. Carbide sealing rings can only be scratched by diamonds or corundum products containing minerals.
Tungsten carbide sealing rings have the characteristics of wear resistance and corrosion resistance, and are widely used in mechanical seals in petroleum, chemical and other fields. The product types include flat rings, table rings and other special-shaped rings. Let's take a look at its features:
1. After fine grinding, the appearance meets the precision requirements, its size and tolerance are extremely small, and its sealing performance is very superior;
2. The corrosion-resistant rare elements are added to the process formula, and the sealing performance is more durable;
3. It is made of high-strength and high-hardness cemented carbide material, which is not deformed and more compressive;
4. The material of the sealing ring must have sufficient strength, hardness, wear resistance, corrosion resistance and impact toughness.
At the same time, the cemented carbide sealing ring also needs to have good processing type and reasonable economical type. Among them, wear resistance, corrosion resistance and thermal crack resistance are the most important requirements. As we all know, cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, even at 500 ° C It also remains basically unchanged at a certain temperature, and it still has a high hardness at 1000 °C. Therefore, the 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. According to different binder phases, cemented carbide sealing rings can be divided into various grades. According to ZZCT's many years of production experience, users use more cemented carbide sealing ring grades of 6% Ni and 6% Co cemented carbide materials. Its brand cemented carbide sealing ring has higher hardness and wear resistance, and its corrosion resistance is also superior.
Zhuzhou Century Tool can provide customers with customization of cemented carbide seal rings of various specifications and models, and can carry out special production customization according to the user's drawings. The seal rings produced meet: small concentricity, high precision; Uniform force; long service life; stable quality and performance.
