Cemented Carbide Sealing ring

Carbide sealing rings occupy a certain position in the sealing ring market. Compared with silicon carbide sealing rings, they have their own advantages and disadvantages in performance. Many laymen may not know much about carbide sealing rings. Today, Entide will take you to understand what carbide sealing rings are and what they do? What are the features?

1.Definition of carbide sealing ring

Carbide sealing rings are made of carbide (WC, TiC) micron powder of high-hardness refractory metal as the main component, with cobalt (Co) or nickel (Ni) and molybdenum (Mo) as binders, and are pressed into a ring shape. A powder metallurgy sealing ring sintered in a vacuum furnace or hydrogen reduction furnace.

2.The function of cemented carbide sealing ring

The carbide sealing ring is an annular seal with a notch. The sealing ring is placed in the ring groove of the sleeve. The sleeve and the shaft rotate together, and the sealing ring is resisted by the elasticity of the notch being pressed together. Tightly attached to the inner hole wall of the stationary part, it can play a sealing role. The sealing ring is the general term for the moving ring and the static ring, and is the main component of the mechanical seal. The sealing ring determines the performance and life of the mechanical seal to a large extent, so the performance requirements are also very high.

3.Carbide sealing ring composition

The matrix of the cemented carbide sealing ring is composed of two parts: one part is the hardened phase; the other part is the bonding metal.

4.Performance applications of carbide sealing rings

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 a temperature of 500°C, still has high hardness at 1000°C. Carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drill bits, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used for cutting Heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult-to-process materials. It is widely used in mechanical seals in petroleum and chemical industries.
