Because the delay in procurement of Minmetals , the State Reserve did not implement , businesses and more pessimistic view of the market outlook , the latter considered weak prices . Tungsten market temporarily stabilized, many businesses on the sidelines, caution , the market traded subdued .

According to research is understood that due to funding tight , hold stocks more choices cash transactions , without cash shipments will not. About 60 degrees Scheelite mainstream transaction focused

Tungsten Market : As mines and cargo operators reluctant to sell sentiment strong, ore, tungsten concentrate purchases more difficult, prompting two days of tungsten concentrates offer a slight uplift. However , the mainstream transaction continuous light, and not much change in transaction price , expected short-term maintenance of stability of tungsten ore market or continue to run .

Carbide with high hardness, wear resistance, strength and toughness, heat resistance, corrosion resistance and a series of excellent performance, widely used as a carbide tool material that can be used to cut heat-resistant steel, stainless steel, high manganese steel, materials difficult to machine tool steel. The new carbide cutting tools carbon steel equal number of times. Modern machining, cutting 70% of the time the entire machining time is an important direction to improve processing efficiency . Carbide end use at least 20% can be increased processing efficiency, reduce processing costs by 15% . Advanced manufacturing and processing technologies to support the development of key tools . Therefore, the proposed development of advanced manufacturing China, has a strong carbide industry is a prerequisite, it also brings out the historic opportunity carbide industry.

High-end products is heavily dependent on imports, import substitution huge market potential.

Carbide world market annual sales of about 3.8-4.0 million tons. Of about 40 % of world production , is the world's largest producer, total annual exports about 4,000 tons of carbide , accounting for 40 % of the world market liquidity , as the first supplier. However, the cutting blades of the highest value-added output of only 3,000 tons , accounting for only 20%.

90% of high-end carbide blade knives dependent on imports . Thus , a single from the existing market capacity , the high-end domestic carbide achieve significant import substitution space. In addition, the future market capacity point of view, China has entered the stage of manufacturing upgrade , but the high-end equipment manufacturing , and information industries included in the pillar industry of the national economy , which will greatly promote carbide blade knives , drill bits , etc. a series of demands , prospects immeasurable.

High-end manufacturing will lead to the development of high-end Carbide .

First, as the mother of the machine manufacturing industry, especially the growth of CNC machine tools will increase by leaps and bounds carbide blade machine tool market . To a machine tool with a dozen or more species , and is a consumable item . China's machine tool production in 2009 into the world, China's imports of all types of knives over the same period increased by 64%. Indicates that China's domestic market demand and the tool is not a problem , backward production . The next five years , China's machine tool industry is expected to maintain a 30% annual growth rate. Secondly , the construction of railways and urban rail shield machine carbide demand will bring rapid growth. Supplies in the shield machine tool belongs , the shield tunneling machine per 200 m -300 m going to replace a hob drill . By 2015, the National Underground Railroad mileage is expected to reach 3,900 km by 2020 , this figure is expected to reach 7,000 kilometers . Third, the inclusion of the pillar industries of the information industry base PCB sub-sectors will maintain an average annual growth rate of 9.3% over the next five years is expected to increase consumption of nearly 40 billion yuan PCB drill . Finally, the address of exploration, underground mining in the 60% ​​-80 % of the amount of drilling completed by carbide drill bits , with the lower -grade mines and mining depth increasing , mining carbide in the next five years is expected to maintain consumption 30% annual growth .

Carbide Die is ten times the life of steel and even a few times, with a high hardness , high strength , corrosion resistance, high temperature resistance and low coefficient of expansion , usually cobalt- tungsten carbide . Carbide since the beginning of the 1920s , with its "widia" like the name of the diamond market since the German scientist by the invention , and the first production of tungsten tensile modulus get industrial applications , replacing the current price of expensive diamond drawing die .

Our Carbide started late , but rapid development . According to reports , at present, carbide die basically serialization and standardization. In recent years the development of the situation, the theoretical study of carbide tooling and design has a deeper and more science, applied more widely .

In the development of new alloy materials on behalf of a few years ago to drill for the hot iron and nickel . Metallurgical materials such as Hunan province developed the equivalent of YG, YG20, YG25 the strength and toughness of cemented carbide, received good results in for cold heading die , cold extrusion die and so on. Tianjin Institute on behalf of the iron-nickel carbide drill also developed a considerable YG1520 carbide die materials , standard parts in the roll forging , cold heading steel ball fairly with regard YG20 effect.

In recent years, new research is popular fine grain , ultra-fine grain , and even gradient nanocrystalline carbide and carbide . There are gradient cemented carbide composition gradient , gradient structure , in addition to the molten metal is also useful to produce osmotic gradient cemented carbide processing methods , such as the top of the gradient cemented carbide hammer .

Fine grain and ultrafine grain carbide also available, such as fine-grained YGS drawing dies while drawing <φlmm wire , is three times the normal drawing mode .

In addition, cast- inlaid carbide hot die , and achieved good results in terms of rolling and wire rod rolling .
