As a kind of hard material, cemented carbide roll ring is composed of hard phase (tungsten carbide), metal binder phase (usually metal cobalt, nickel) and trace rare metal elements. Its performance is determined by the content of binder metal and Determined by the size of tungsten carbide particles.

Industry analysts pointed out that cemented carbide roll rings are also called tungsten carbide alloy roll rings. They are an important component that consumes a lot in the rolling of steel rods and wire rods. It is also closely related to the apparent quality, dimensional accuracy and cost of the rolled steel. Related.

The cemented carbide roll ring has good turnability, no special lathe is needed, and the existing ordinary lathe can be used to groove the roll ring. When turning, the cutter head can be made of hard alloy with high hardness. There are two types of cemented carbide rolls: integral type and combined type.

Cemented carbide roll rings are mainly used for the production of high-speed steel and other steel processing products. The proportion of lower-end products in the current market is much lower. However, with the improvement of people’s living standards in the future and the enhancement of environmental Roll ring market demand will increase

In recent years, my country's cemented carbide industry has developed rapidly. There are many cemented carbide products, a wide range of applications, and the rapid development of the industry, which in turn stimulates the demand for the cemented carbide roll ring market and the development of the cemented carbide roll ring industry. From January to June 2014, my country's cemented carbide roll ring industry demand reached 856 million yuan, an increase of 26% year-on-year. In 2013, my country's cemented carbide roll ring industry demand reached 1.682 billion yuan, an increase of 100 13.1 in.

At present, my country is the world's largest exporter of cemented carbide roller rings, and the export volume accounts for most of the global market share. The export markets are 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. With the improvement of people's living standards and environmental protection awareness, the adjustment of national policies and the specifications of industry associations, cemented carbide is used to manufacture The market proportion of cemented carbide roll rings will gradually increase. The domestic market’s market demand for cemented carbide roll rings will increase, and the export proportion will decrease. Among the export products, the export proportion of products will increase.

The main raw material for hardened alloy roll rings is tungsten carbide, and the main content of the binder is cobalt. The price fluctuation of the main raw materials affects the production cost of the hardened alloy roll ring industry, which in turn affects the profitability of the hardened alloy roll ring industry. The reserves of tungsten and cobalt are small and unevenly distributed. Coupled with the consumption of long-term industrial development, these two raw materials are becoming increasingly depleted, and the fluctuations are very uncertain. From 2014 to 2018, Price fluctuations will still exist. The increase in the price of raw materials will increase the production cost of hardened alloy roll ring manufacturers and reduce profitability. Therefore, hardened alloy roll ring manufacturers should take measures to reduce the impact of raw material price fluctuations on the company, such as the integration of the industrial chain.

The "2014-2018 China Cemented Carbide Roller Ring Industry Analysis and Market Development Research Report" shows that the hardened alloy roll ring has high technical requirements and there are many small and medium-sized enterprises in the industry. With the development of the industry, the market demand for high-performance products will Will gradually increase, some small and medium-sized enterprises have weak technical strength and insufficient scientific research investment expenditure. They will gradually be eliminated in the future market competition. With the emergence of economies of scale and the improvement of technological level, the application range of products will expand. The overall profitability level will be improved.
