The cemented carbide sealing ring is made of tungsten carbide powder as raw material, adding an appropriate amount of cobalt powder or nickel powder as a binder, pressing it into an annular shape through a certain mold, and sintering it in a vacuum furnace or hydrogen reduction furnace. It is a relatively common production and processing product in cemented carbide manufacturers. Because it has high hardness and good anti-corrosion performance, and strong sealing, it has many applications in petrochemical industry and other sealing industries
Cemented Carbide sealing rings are made of hard metal, which is stronger than titanium rings and more durable than gold rings. It is also very hard, but not easy to scratch. Hard alloy seal 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, so they are widely used in mechanical seals in petroleum, chemical and other fields. Let's take a look for the features:
1、After fine grinding, the appearance can meet the accuracy requirements, as well as extremely small dimensions tolerances, and excellent sealing performance;
2、Corrosion-resistant rare elements are added to the process formula, so 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 machinability and reasonable economy. Among them, wear resistance, corrosion resistance and hot cracking resistance are the most important requirements. As we are well aware, cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, especially its high hardness and wear resistance, which remains basically unchanged even at a temperature of 500 °C, and still has a high hardness at 1000 °C. As a result, tungsten carbide sealing rings are the most widely used products 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 bonding phases, tungsten carbide sealing rings can be divided into a variety of grades. According to Sidi's many years of production experience, users use more cemented carbide sealing rings with 6% Ni and 6% Co cemented carbide materials. Its grade cemented carbide sealing ring has higher hardness and wear resistance, and the corrosion resistance is also superior.
Zhuzhou Chuangrui Cemented Carbide Co., Ltd. can provide customers with a variety of specifications and models of cemented carbide sealing ring customization, according to the user's drawings for special production customization, the production of sealing rings to meet: small concentricity, high precision, high end face flatness, uniform force, long service life, stable quality and performance and other characteristics.
