Crucible GE

Graphite Crucible GE are indispensable for heating, drying, roasting, pouring and melting various substances. The reason for their wide demand lies in the unique qualities of graphite. The main ones are:

High thermal conductivity, the value of which depends on the temperature of use and the temperature regime of processing during production.

Good electrical conductivity that increases with heat.

Resistance to high temperatures.

Inertness with respect to many chemical elements and compounds.

Ability to withstand temperature changes.

An increase in mechanical strength when heated to 2700 K, this graphite compares favorably with most materials.

Metal impermeability.

Graphite crucibles can be operated in vacuum, protective and inert environments at temperatures up to 2000°C and 2300-2500°C, respectively. When oxygen is available, heating up to 400-700 °C (depending on the grade of material) can cause graphite to burn out, so graphite-containing products are produced for use in an oxidizing environment. They are made using a binder, usually highly refractory clay or silicon carbide, which increases not only mechanical strength, but also thermal conductivity.

APPLICATION OF GRAPHITE-CONTAINING CRUCIBLES

For non-ferrous metals:

with a melting point up to 1500 °C - melting in induction and resistance furnaces;

with T pl. up to 1600 °C - melting in resistance furnaces, liquid and gaseous fuel furnaces, induction furnaces;

pouring of metals with working temperature up to 1600°C.

For precious metals:

with T pl. up to 1600°C - melting in muffle and induction furnaces.

with T pl. up to 1250 °C - melting by heating the crucible directly with electric current.
