ULTRA HIGH POWER GRAPHITE CRUCIBLE
The graphite crucible for vacuum smelting of our company's
intermediate frequency furnace is based on imported needle coke,
three high graphite crushed and high-quality modified asphalt as
the main raw materials. After firing at a predetermined temperature
rise curve, it is then impregnated with high pressure, re-fired,
and then graphitized at a temperature above ***0 ° C. The
ultra-high power graphite crucible has the characteristics of
compact and uniform structure, high strength, low resistivity, good
thermal conductivity and high bulk density. It is widely used in
high-frequency smelting of medium frequency furnaces, copper,
copper alloys and non- ferrous metals.
Product specifications: diameter Φ**0 ～ **0 mm, height **0 ～
***0 mm, smelting capacity **0 kg ～ ***0kg.
1.Handle with care during transportation, handling, and
storage. Pay attention to waterproof and moisture-proof. Do not
damage it;
2. Purge the inner surface of the crucible with high pressure
air before use;
3. Handle the smelting material gently, not too violent or too
fast, and damage the inner wall of the crucible;
4. After the smelting is completed, the vacuum furnace can be
destroyed only after cooling to a certain temperature;
5. The first time you pay attention to the slow temperature
rise, it will help increase the service life.

Ultra High Power Graphite Crucible
Ultra-high power graphite crucible has the characteristics of
high temperature resistance, strong thermal conductivity, good
corrosion resistance and long service life. In the process of high
temperature operation, the coefficient of thermal expansion is
small, and it has certain strain resistance to quench and heat. It
has strong corrosion resistance to acidic and alkaline solutions
and excellent chemical stability. It does not take part in any
chemical reactions in the smelting process. The inner wall of
graphite crucible is smooth, and the melted liquid metal is not
easy to leak and adhere to the inner wall of crucible, which makes
the liquid metal have good fluidity and castability. In metallurgy,
casting, machinery, chemical industry and other industries, it is
widely used in the smelting of alloy tool steel and the smelting of
non-ferrous metals and their alloys.
