High Temperature W1 Tungsten Crucibles tungsten pot with lid
Tungsten crucible,It is one of the metal tungsten products, mainly divided into sintering forming (applied to powder metallurgy technology), stamping forming, and spinning forming. Using tungsten rod turning to form (generally small in size), various welding forms are used, and pure tungsten plates, tungsten sheets, and pure tungsten rods are processed through corresponding processes.
Tungsten crucibles can be used in vacuum inert gases below 2600 degrees Celsius. Tungsten has a high melting point and boiling point, good high-temperature strength, anti-wear and corrosion resistance, high thermal conductivity, low coefficient of thermal expansion, and good hardenability. Tungsten crucibles are widely used in industries such as rare earth smelting, quartz glass, electronic spraying, crystal growth, etc·

1. raw material preparation
(Preparation of tungsten billets by powder metallurgy method)
2. Hot rolling forming
(Hot rolling tungsten billets into thin plates that meet design requirements through hot rolling technology, and processing them into circular shapes.)
3. Spinning forming
(Place the processed disc on a hot spinning machine and heat it with a mixed flame of hydrogen and compressed air (about 1000 ℃). After multiple spinning cycles, the shape of the tungsten plate gradually changes to that of a crucible)
4. Cooling to form finished products
(Finally, after a cooling process, a tungsten crucible product is formed)
1. Refining field
Tungsten crucibles can be used for high-temperature smelting and melting experiments of various substances, such as molten minerals, metals, glass, etc.
2. Analyze and test the field
In chemical analysis testing, tungsten crucibles can be used to analyze the composition and structure of various substances, such as testing the purity, content, and deposition of chemical reagents.
3. In the field of electronic materials
Tungsten crucibles can also be used for high-temperature processing of electronic materials, such as high-temperature sintering, vacuum annealing, etc.
The production methods of covered tungsten crucibles mainly include stamping, spinning, welding, and turning.
The lid of a tungsten crucible with a lid has multiple functions, mainly including preventing oxidation reactions, reducing energy loss during the refining process, and preventing the invasion of external impurities.
