China's cemented carbide industry status, market and its developing trend .

1. The present status of China cemented carbide industry
In the tungsten industry, carbide tungsten consumption accounts for about 50% of the total of tungsten consumption. Therefore, the development of cemented carbide industry for the development of the whole tungsten industry plays a very important role. China cemented carbide industry starts from the construction of zhuzhou cemented carbide factory in the early 1950 s, more than 50 years, from scratch, development, obtained the accomplishments that have astonished the world, but the overall technology especially high value added products production and there is still a large gap compared with the advanced world level.    
1.1 achieved rapid development
(1) cemented carbide production: in the early 1980 s, the carbide annual output 25000 tons, China cemented carbide annual output of about 5000 tons. In the 21st century, the world carbide annual output reached 38000 tons, and rapid growth of China's cemented carbide production has been to 15000 tons, more than a third of the cemented carbide production world. Therefore, from the scale of production and production, China is the world's truly the first production of power.    
(2) the hard alloy export: with the further development of China's reform and opening up, China's cemented carbide exports have also made obvious progress, with exports in 1986 reached 100 tons, in 1996 reached 400 tons, in 2006, nearly 5000 tons, in 2013, has more than 25000 tons,
The same as production also accounted for a third of the world carbide market circulation. In the foreign exchange earning less than $4 million a year from the past, also increased to $270 million a year or so now.  
(3) complete basic varieties: relating to the application in the metal cutting, mining, drawing die, wear parts, such as in various fields, including its deep processing products, in addition to high performance precision grinding coating blade and the supporting tools, high-performance ultra-fine alloy rod and small amounts of different products to be imported from abroad, the vast majority of products can produce in China.    
(4) equipment and technology constantly improve: in recent years, the Chinese used in cemented carbide production equipment manufacturing industry developing rapidly, the production technology level of the equipment is also rising, for cemented carbide enterprise equipment updated created favorable conditions. Some strength strong enterprise again on this foundation, through its own scientific research as well as the necessary technical introduction, the overall level of production equipment and technology has greatly improved. Automatic milling equipment, efficient ball mill, spray drying, granulating, high precision automatic press, vacuum dewaxing sintering furnace, pressure sintering furnace, grinding, coating and a series of advanced equipment and technology has been applied to different manufacturers have different degree.
(5) the hard alloy scrap recycling achievements: scrap tungsten utilization in China are constantly enterprise seriously, only hard alloy scrap by electrolysis, zinc solution techniques such as recycling of tungsten carbide, cobalt oxalate, mixture, reprocessed using carbide production perfection of production has more than 3000 tons/year, account for more than 20% of China's cemented carbide production. These alloys except meet the demand of part of China's industry itself, and to provide some reasonable ratio of cemented carbide products abroad, gives valuable tungsten resources is more reasonable to use.
