Production process of tungsten cube
Materials---hot rolling---annealing---cold rolling---leveling---annealing---machining---tungsten sheet
Production equipments
four-high cold mill, vacuum annealing furnace, W43G series straightener, hydraulic plate shears, water jet, wire cutting machine, flat-stone mill
Applications of Tungsten cube
Since the melting point oftungstenhas reached 3380oC,tungsten sheetis widely used in reflection shield, cover plate applied in the sapphire growth furnace, reflection shield, heating tape, connecting pieces applied in vacuum furnace, sputtering target applied in plasma coating film, and high temperature resistance boat.
