14 Chinese Society of Rare Earths , said purchasing and storage of rare earth is expected to honor the month , is expected to reach ten billion yuan entire purchasing and storage tray . There are six participating companies , purchasing and storage varieties praseodymium , neodymium oxide, dysprosium and other heavy rare earth . Society of Rare Earths sources said the policy of promoting downstream applications is also brewing in rare earth stocks will usher in the outbreak .

The United States and Europe are on the Chinese rare earth export policy sued to WTO, the outcome of litigation fastest at the end of the outcome. To this end, China is brewing a number of New Deal response to export changing situation , including smuggling crackdown , the proposed introduction of "Rare Management Regulations" , the formation of large groups , and prepare different varieties of rare earth differentiated management. The end of September , at the national level , " self-examination " has ended, this month ushered in more intensive peer review . Meanwhile , the industry is expected to round the heavy rare earth purchasing and storage efforts, some varieties of global purchasing and storage size may exceed 50% of annual consumption . Despite lower demand in general , but a catalyst for continuous fermentation supply contraction will push up the earth offer.

Multiple composite rare earth tungsten electrode is a new non-polluting materials , its comprehensive welding performance , can replace radioactive thorium tungsten electrode . Under the same conditions, multivariate test specification composite rare earth tungsten electrode arc performance at or better than the same size thorium tungsten electrode , the critical arc starting voltage of only 32.6VB. 20 minutes at rated current test specification composite rare earth electrode under the same specifications than burning thorium tungsten electrode burning low 0.5mg or more.

Recently, the national " 15" 863 project " multiple composite rare earth tungsten electrode materials industry key technology research" through research cooperation , developed with independent intellectual property rights of multiple composite rare earth tungsten electrodes full industrial technology , can substitute the thoriated tungsten electrode .

Tungsten is a kind of widely used welding, plasma welding, spraying, cutting technology and metallurgical industry in the critical heat source materials currently in use around the world more than 70% tungsten electrodes are still contaminated with radioactive thorium tungsten electrode , severe pollute the environment and endanger human health. The project research breakthrough material composition , manufacturing process and equipment, and testing equipment and other core technology , invented the integrated welding performance is better than the existing multi- thorium tungsten electrode composite rare earth tungsten electrodes , the development of multiple rare earth tungsten electrode preparation APT direct doping, large temperature gradient reduction , low current vertical melt sintering technology, the formation of rare earth tungsten electrodes industrial production process to achieve efficient production and quality control . New products have been diversified rare earth tungsten electrodes to achieve industrial-scale production and quantities.

China's " multiple composite rare earth tungsten electrodes and preparation technology " results recently passed expert appraisal. The study by Beijing University and Beijing General Research Institute of Mining and Metallurgy Beijing Tungsten & Molybdenum Material Factory co-developed multi-composite rare earth tungsten electrodes series of new products , manufacturing process and equipment, and testing equipment , such as full industrial technology , products, overall performance is better than radioactive thorium tungsten electrode to solve China's relevant materials industry is a major technical problems.

Tungsten is a kind of widely used welding, plasma welding, spraying, cutting technology and metallurgical industry in the critical heat source material , tungsten electrodes used worldwide each year the total consumption over 1600 tons . But currently using tungsten electrodes that there is still more than 70% of radioactive contamination thoriated tungsten electrodes , seriously polluting the environment and endanger human health. "multiple composite rare earth tungsten electrodes and preparation technology" project independently developed a diverse composite rare earth tungsten electrode material , not only integrated performance , but because they do not use radioactive elements thorium , to achieve a non-radioactive contamination in the field of green production and be used.

Chen Yunbo other three by the Academy of Sciences, 863 new materials technology special functional materials such as technical subject matter expert Chow head 13 experts appraisal committee believes that the project overall technology has reached the international advanced level. Project main features and innovations embodied in the establishment of a composite rare earth tungsten electrode burning model , explaining the electrodes wear mechanism reveals multiple composite rare synergy mechanism , proposed the use of rare earth complex synergistic composition design principles , invented the integrated welding performance is better than the existing multi- thoriated tungsten electrode composite rare earth tungsten electrodes ; proven rare earth tungsten electrodes multivariate powder metallurgy and plastic processing and other preparation processes were investigated to develop a diversified preparation of rare earth doped tungsten electrodes directly APT complex, large temperature gradient reduction , low current vertical melt sintering technology , the formation of rare earth tungsten electrodes for industrial production processes ; integrated innovation developed production line key equipment , to achieve efficient production and process quality control, industrial production yield than the current thorium tungsten 5% higher than the class -leading levels of materials processing , and the establishment of domestic rare earth 's first multi-composite tungsten electrode production lines with annual production capacity of 120 tons .
