  B. product introduction;

Graphite crucible is mainly used for melting metal materials, which can be divided into natural graphite and artificial graphite.

1) Natural graphite

It is a natural flake graphite as the main raw material, adding clay and other refractory made of quality raw materials, generally called clay graphite crucible, and called for asphalt binder bonded carbon dosage forms of crucible, clay sintering force alone binder dosage form called emblem made of clay crucible, the former is superior in terms of strength and thermal shock. It is used for the melting of steel, copper, copper alloy and other non-ferrous metals of various sizes with melting capacity ranging from 250g to 500kg.

This type of crucible includes accessories such as skimmer spoon, cap, joint ring, crucible holder and stirring handle.

2) Artificial graphite

The natural graphite crucible mentioned above usually contains about 50% clay-like minerals, while the artificial graphite crucible has impurities (ash) of less than 1%, which are used for refining high-purity metals, and highly pure graphite (ash <20ppm) which have been specially purified. Artificial graphite crucibles are often used to melt small amounts of precious metals and high purity metals or high melting point metals and oxides. It can also be used as a crucible for gas analysis in steel.
