Status and Analysis of China Cemented Carbide Tools

In 2012, China's cemented carbide production was 23,500 tons, cemented carbide industry sales revenue was 20.9 billion yuan, cemented carbide exports nearly 5,000 tons, exports earned more than 360 million US dollars, and cemented carbide deep processing products reached 6,600 tons, accounting for total alloys. One-third of the output. By 2014, China's cemented carbide production reached 27,200 tons, and the industrial sales value reached 30.686 billion yuan. Cemented carbide is mainly used in cutting tools, mining tools, molds and high-pressure high-temperature chambers. The proportion of cutting tools and mining tools accounts for 33% and 25% of cemented carbide applications, respectively.
Carbide tools need to connect the cemented carbide and steel matrix by brazing. The current welding process is mainly induction brazing. According to statistics, the number of induction welding machines used in the industry exceeds 500,000 units. However, China's cemented carbide tools have the problem of disjointed production of alloys and tools. Before 2002, 70% of the brazing filler metal industry relied on imports, which greatly restricted the development of China's cemented carbide tools. In 2002, Zhengzhou Machinery Research Institute took the lead in introducing special brazing tools for cemented carbide tools, which promoted the development of China's cemented carbide tools. By 2014, there were more than 3,000 manufacturers of cutting tools and mining tools in China, and the sales value of cutting tool industry exceeded 35 billion yuan. The output value of mining tool industry exceeded 20 billion yuan. The demand for brazing materials for cemented carbide tools More than 1 billion yuan, the consumption of flux exceeds 50,000 tons.
At present, the opportunities and challenges of China's cemented carbide tool manufacturing industry coexist, but overall, the favorable factors of industry development occupy a dominant position. The brazing alloy tool and the magnetizing flux driving technology developed by Zhengzhou Machinery Research Institute have filled the domestic blank. The brazing materials are widely applied to more than 700 enterprises, and the magnetizing flux driving technology is applied to more than 100,000 induction brazing. Welding equipment has significantly promoted the development of the upstream and downstream industries of cemented carbide materials.
