鎢坩堝

Tungsten crucible is one of the tungsten products. It can be processed by sintering, stamping and rotatable machining. Sintered product is manufactured by powder metallurgy technology. The most common application of sintered products is the crucible in the melting furnaces. Tungsten crucibles can be manufactured from pure tungsten plates or rods through machine shaping and welding processes. Tungsten crucible is widely applied in sapphire production, also used in quartz glass melting furnace, rare earth smelting furnace and other furnaces as the core container. The melting point of tungsten is 3410 ℃. The production process of tungsten crucible is: tungsten powder-sieving-furnace apart-isostatic pressing-lathe machining-medium frequency sintering-second lathe machining-packing.
