As a hard material, the hard alloy roller ring is composed of a hard phase (tungsten carbide) and a metal bonding phase (usually cobalt and nickel) and trace rare metal elements. Its performance is determined by the content of the bonding metal and The tungsten carbide particle size is determined. Cemented carbide roll rings, also known as tungsten carbide alloy roll rings, are important parts with relatively large consumption in the rolling of steel rods and wires, and are closely related to the apparent quality, dimensional accuracy and cost of the rolled steel.

　　 Carbide roll ring has good turnability, no special lathe is needed, and the existing ordinary lathe can be used to roll groove the roll ring. When turning, the tool head can be made of high-hardness carbide tool material. Cemented carbide rolls are available in two types: integral and combined. Carbide roller rings are mainly used to produce high-speed steel and other steel processing products, and the proportion in the current market is much lower than the low-end products. However, with the improvement of people's living standards and the enhancement of environmental awareness in the future, high-grade hard The market demand for alloy roll rings will increase.

　　In recent years, my country's cemented carbide industry has developed rapidly, with many cemented carbide products, a wide range of applications, and rapid development of the industry, which in turn has driven the demand for the cemented carbide roll ring market and promoted the development of the cemented carbide roll ring industry.

　　 my country is the world's largest exporter of hard alloy roll rings, and its export volume accounts for most of the global market share. The export market is mainly developed countries such as Europe, America, the United States, and Japan. In the future, with the rapid development of the domestic steel industry, the market demand for cemented carbide roll rings will increase, and with the improvement of people's living standards and environmental awareness, the adjustment of national policies and the regulations of industry associations, they will be made of cemented carbide The market share of cemented carbide roll rings will gradually increase, which will eventually increase the market demand for cemented carbide roll rings in the domestic market, and the export rate will decrease. Among the exported products, the export rate of high-end products will be Improved.
