Production engineering
tungsten powder——size sorting,grading——forming(cold isostatic press)—— sintering(IF induction sintering furnace) ——Hot rolling(Two roller reversible hot rolling mill)——Leveling and annealing——Pickling or caustic washing——Warm rolling(Four-roller reversible cold rolling mill)——Leveling and annealing——Cold rolling(Four-roller reversible cold rolling mill)——cutting(hydraulic cutting plate machine)——Vacuum annealing(Vacuum annealing furnace)——Machining,Wire cutting,flat grinding——testing——packing
6. Application:
Tungsten has a unique property of which it's melting point can reach ***0 tungsten is widely applied in high temperature vacuum furnace melting environment such as sapphire growing furnace, quartz glass melting furnace, and rare earth melting furnace. For sapphire crystal growing furnace, high-purity, high-density, no crack tungsten crucible with other features of exact measurement and smooth surface has decisive influence on the success of crystal growth, quality control of pulling crystal, discharging and service life during sapphire growing process.
