Tungsten Industry Association for the past two years, the tungsten market movements were carefully analyzed

Tungsten Industry Association for nearly two years to conduct a careful tungsten market trend analysis, that there are three major characteristics: First Scheelite 100,000 yuan / ton price has been on the market psychologically and downstream enterprises to accept and in fact recognized ; Second, market pricing has the right to speak turned upstream and downstream enterprises are gradually transition  molybdenum electrode  ; Third, the supply and demand sides and slowly get rid of impulsive feeling , psychologically more mature , and in the price has been stable . With this foundation , the steady growth in demand , under the premise of binding supply environment at the same time to enter the market once the demand ,  sandblasted tungsten target  the price of tungsten is in the affirmative , the inevitable rise in the price of tungsten manifested . Kong Zhaoqing pointed out that the stability of demand, supply constraints of mature psychological, as well as downstream into harmony on four major factors supporting the market and prices. China's influence on the global tungsten market is bound to increasingly enhanced. The reason why in the last two years the city of tungsten high, some experts believe is the result of many factors , both countries to strengthen macro- economic role to maintain stable development , but also to strengthen its own adjustments , price reasonable return factors , while there are other factors at home and abroad .

Rich northern Jiangxi Tungsten

Big HUTANG sandblasted tungsten target ore exploration and development in North Jiangxi Tungsten Industry is a microcosm of the rise. , Small metal, scrap metal. According to the latest exploration results, northern Jiangxi Wuning County, Xiushui County and Jingdezhen Fuliang County is rich in tungsten and awaiting development
Following the 2010 discovery in northwestern wuning large HUTANG large tungsten mine after the beginning of this year, Jiangxi Bureau of Geology and again in northeastern Jiangxi Jingdezhen Fuliang County, Zhu Xi mine discovered a world-class large tungsten mine, has penetrated maximum thickness of 449 m ore, tungsten ore highest grade of 8%, with an average grade of 0.64% to 0.65%, equivalent to five times the industrial grade. Copper Lead Zinc Tin CNMN.COM.CN nickel, China Nonferrous network, a small metal, scrap metal. Jiangxi Bureau of Geology and Mineral Resources Secretary Pengze Zhou said: "This time, Zhu Xi mine major discovery, prospecting breakthrough strategic action is an important achievement, it makes tungsten ore resources in Jiangxi Gannan formed in northeastern Jiangxi Province, northwestern three pillars of the new pattern, and further consolidation of tungsten ore resources in the world dominance., small metal, scrap metal. "
The world's proven reserves of tungsten ore are mainly distributed in China. Small metal, scrap metal. According to the U.S. Geological Society data, as of the end of 2012, the world's proven reserves of tungsten metal content reached 3.2 million tons, China accounted for 61%. Copper Lead Zinc Tin CNMN.COM.CN nickel, China Nonferrous network, a small metal, scrap metal. China is the world's largest supplier of tungsten, tungsten supply China accounted for 80% of global demand. Copper Lead Zinc Tin CNMN.COM.CN nickel, China Nonferrous network, a small metal, scrap metal. Chinese tungsten concentrate resources development in Jiangxi, Hunan, Henan and Guangxi provinces, including Jiangxi fine mineral country accounts for 46.45%, accounting for 25.78% of Hunan, Henan, accounting for 11.57%. Copper Lead Zinc Tin CNMN.COM.CN nickel, China Nonferrous network, a small metal, scrap metal. The existing tungsten concentrate production in Jiangxi Province, eight in Ganzhou. Copper Lead Zinc Tin CNMN.COM.CN nickel, China Nonferrous network, a small metal, scrap metal.
With tungsten ore exploration in northern Jiangxi real progress, it will change the thriving southern Jiangxi Tungsten Industry pattern. Copper Lead Zinc Tin CNMN.COM.CN nickel, China Nonferrous network, a small metal, scrap metal.
With the Department nine Ridge Mountains, wuning neighboring counties, the south side of the Great Lakes Xiangtangxi Xiushui County found censer Alexander tungsten mine. Copper Lead Zinc Tin CNMN.COM.CN nickel, China Nonferrous network, a small metal, scrap metal. The tungsten ore amounted to 216,000 tons of proven reserves, the development side Jiangxi Xiushui Xianglushan tungsten industry limited liability company by CMN, LIU Dian level control of Xiushui county divinity Mining companies and Xiushui County Mining Corporation in accordance with the 51%, 44 %, 5% funded. , Small metal, scrap metal. Xianglushan tungsten ore concentrates has reached an annual output of 5,500 tons, supporting the establishment of the North Jiangxi Tungsten Industry Co., Ltd. has APT smelting capacity 5000 to 10,000 tons / year. Copper Lead Zinc Tin CNMN.COM.CN nickel, China Nonferrous network, a small metal, scrap metal.
However, the industry believes that the northern Jiangxi Tungsten Industry to form and Gannan considerable status will be a fairly lengthy process. Copper Lead Zinc Tin CNMN.COM.CN nickel, China Nonferrous network, a small metal, scrap metal.
Tungsten industry sources, a large tungsten mine expansion targets HUTANG Land Department to obtain approval of a certain degree of difficulty. Copper Lead Zinc Tin CNMN.COM.CN nickel, China Nonferrous network, a small metal, scrap metal. In order to protect scarce resources, the implementation of China's current total control of tungsten mining, "second five" plan proposed goal of total control of tungsten increased by only 1 percent per year. Copper Lead Zinc Tin CNMN.COM.CN nickel, China Nonferrous network, a small metal, scrap metal. 2013 Tungsten mining overall index slightly lower than the previous year. Copper Lead Zinc Tin CNMN.COM.CN nickel, China Nonferrous network, a small metal, scrap metal. 2012 issued by the Department of Homeland approved annual output of 90,000 tons, 30,000 tons of Jiangxi assigned targets, of which 25,000 tons or so points to the "World tungsten" Ganzhou Jiang and tungsten.

Chemical vapor deposition of tungsten ingot Process

In WF6 and H2 as raw materials, powder metallurgy sandblasted tungsten target plate as the substrate, the open pipe by hot filament chemical vapor deposition gas flow test device, the deformable successfully prepared tungsten ingots. Experimental analysis showed that: tungsten ingot purity of 99.9%, a density greater than 19.0g/cm3, hardness of 400 ~ 500HV, has good processing plasticity. Studied the tungsten ingot microstructure and properties in the rolling deformation changes and the factors affecting its hot performance.

0 Introduction tungsten as an extremely wide range of refractory metal applications, which is mainly used for production of tungsten plate temperature standard light, tungsten evaporation boat, tube gate, heat shield, high temperature furnace components, X-ray tube tungsten target, etc. [1]. Tungsten high melting point, high temperature strength, but easily oxidized sublimation temperature brittleness, forming rather poor, so the current production of tungsten plate, the widespread use of tungsten ingot metallurgy sintering method.
