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 .

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 .

Tungsten scrap prices continue to hold steady. Currently scrap tungsten drill focused on the purchase price excluding tax mainstream 185-188 yuan / kg, imported scrap tungsten blade 176-180 yuan / kg, domestic waste tungsten blade 167-170 yuan / kg, scrap wire drawing dies 178-181 yuan / kg Waste pure tungsten 213-221 yuan / kg. W ≥ 70% concentrated in the purchase price of the grinding material mainstream 1.75-1.8 yuan / kWh; 50% <W <70% ,1.65-1 .75 yuan / kWh; 30% <W <50% ,1.45-1 .55 yuan / kWh, steady .

In the mining and cargo operators reluctant to sell emotional support, tungsten ore market is becoming strong. Tungsten scrap market continues to maintain a steady trend, height tungsten scrap material resources are still tight, the price is relatively strong, scrap tungsten steel business mentality calm, the price adjustment will is not strong, steady watching the majority. Tungsten scrap market is expected to more than short-term steady trend will continue.

[International] overseas markets were mixed tungsten City. 23 evening MB ferrotungsten Rotterdam quote 41.5-42 USD / kg tungsten, down $ 0.4-0.5; paratungstate Europe quoted 365-380 U.S. dollars / metric ton, $ 5 on expensive exploration; quotation 362-370 U.S. dollars / metric ton, continue steady. Expected short-term overseas tungsten Costco will continue to narrow adjustment.
