Carbide sealing rings occupy a certain seat in the sealing ring market. Compared with silicon carbide sealing rings, there are advantages and disadvantages in performance. Silicon carbide sealing ring belongs to the class of silicon carbide ceramics and is produced according to the preparation method of silicon carbide ceramics. So what are carbide seal rings? What are the characteristics?

   1 Definition of cemented carbide sealing ring Cemented carbide sealing ring is mainly composed of carbide (WC, TiC) micron powder of high hardness refractory metal, with cobalt (Co) or nickel (Ni), molybdenum (Mo) It is a powder metallurgy sealing ring that is pressed into a ring shape and sintered in a vacuum furnace or hydrogen reduction furnace.

   2 The composition of the cemented carbide sealing ring The matrix of the cemented carbide sealing ring consists of two parts: one part is the hardening phase; the other part is the bonding metal.

   3 Performance application of cemented carbide sealing ring 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, even at 500 It remains basically unchanged at the temperature of ℃, and still has a high hardness at 1000 ℃. Carbide is widely used as tool material, such as turning tools, milling cutters, planers, drills, 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 Difficult-to-machine materials such as heat-resistant steel, stainless steel, high manganese steel, tool steel, etc. The cutting speed of new carbide tools is now hundreds of times that of carbon steel.
