4. Various specifications and shapes of special type parts can be produced according to the needs of users: Boat, crucibles, funnels, barrel, molybdenum tubes and various kinds of special liquid- flow hole panel, etc.
Pure tungsten products: tungsten powder, slab, bars, rolling plate, sheet, rods(electrode), wire, crucible, boat, funnel and other special shape , etc..
5. Tungsten crucible is used for smelting of rare earth metals, heating elements of induction furnace, heating elements of rare earth metals, smelting of quartz, glass and for high-temperature containers.
Also used in high temperature vessels for smelting of rare earth metals.
And main applications: For making rotors of aircraft wings, shileding materials for radioactive isotope (Cobalt 60), and for materials of armor piercing bullets and mould, etc.
Spinned crucibles are made of high-quality plates through exclusive spinning crucible equipment of our company. The spinning crucibles of our company feature accurate appearance, uniform thickness transition, smooth surface, high purity, strong creep resistance, etc.
Welded crucibles are formed by welding high-quality tungsten plates or molybdenum plates through sheet metal working and vacuum welding technologies. The welded crucibles of our company feature good roundness, smooth welding seams, good firmness, no air leakage, etc.
Sintered crucibles are made of high-quality tungsten powder or molybdenum powder through strict screening, mixing, blank setting, pressing, powder turning and other processes, with scientific control over sintering temperature gradient and long insulation time. In cooperation with a hot isostatic pressing process, the crucibles can achieve the features of high density, fine crystal grains and good molding.
