Tungsten electrode is a kind of wide application solders at argon arc solder, plasma, the material of crucial heat source in technology of spray, cut and metallurgical industry, the whole world uses the total wastage of tungsten electrode every year to exceed 1600 tons. But 70% above remain the tungsten electrode that uses at present the thorium tungsten electrode that has radioactivity pollution, polluting environment and harm mankind health badly. "Multivariate and compound electrode of rare earth tungsten and its preparation technology " what own development gives the project is multivariate and compound material of electrode of rare earth tungsten, not only integral performance is superior, and because do not use radioelement thorium, the pollutes without radioactivity green that realized this domain is produced and use. Our country " multivariate and compound electrode of rare earth tungsten and its preparation technology " achievement passed expert appraisal a few days ago. This is studied by Beijing industry university and Beijing mine smelt metal factory of material of tungsten of total courtyard Beijing cooperates of research and development multivariate and compound craft of new product of series of electrode of rare earth tungsten, preparation and equipment, and detect the technology of complete set industrialization such as equipment, radioactivity of excel of product integral performance thorium tungsten electrode, solved the difficult problem of one old technique of industry of our country relevant data.
