Tungsten crucible W1

Tungsten melting point, high boiling point, high-temperature strength, corrosion resistance, high thermal conductivity, small thermal expansion coefficient, and good hardenability, thanks to such excellent characteristics, tungsten crucible is widely used in quartz glass, rare earth smelting, crystal growth, electronic spraying, and other industries. Tungsten steel billets are first made by powder metallurgy, then rolled into thin sheets of design thickness by the hot rolling process, and then processed into discs. Which were then placed on a hot spinning machine. After many rotations, the tungsten plate takes the shape of a crucible. After cooling, the spinning tungsten crucible was obtained. The production process of forging tungsten crucible: 1. The density of blank is generally 90% ~ 95%. 2. The prepared tungsten rod is heated in a hydrogen furnace for a period of time, and then the blank is forged. 3. Annealing processing.
