The development of new type of hard full mould materials market analysis

Carbide since early 20 s of this century invented by scientists in Germany, with its' widia ( Like a diamond) 's name, and the first production of tungsten wire drawing die for industrial applications, to replace the expensive diamond drawing die at that time. Although carbide in China started late, but development is rapid. At present, the carbide mold has largely serialization and standardization. From the point of development in recent years, China's cemented carbide mould research and design theory has been more and more scientific, and more widely applied. On the development of new type cemented carbide material, a few years ago to drill for the hot iron nickel generation. Such as hunan province metallurgy materials developed by equivalent to YG, YG20, YG25 high toughness carbide, such as used for cold heading die, cold extrusion die has received good results. Tianjin institute of carbide and iron nickel generation drill developed quite a while ( 15 - 20) Carbide die material, in terms of standard roll forging, steel ball cold heading and YG20 effects. Popular in recent years, new research is fine grain, ultra fine grain, even nanocrystalline cemented carbide with gradient cemented carbide. Gradient cemented carbide and composition gradient, gradient structure, etc. , it is also useful metal molten infiltration treatment method to produce the gradient cemented carbides, such as gradient cemented carbide anvil. Fine and ultrafine silicon carbide crystal have been listed, such as fine grain YGS drawing die in drawing < phi LMM wire, is three times as many general drawing die. In addition, there are set casting, enchase hard alloy hot-work die, in the tube and wire rod rolling has achieved good results.
