Graphite Crucible major components of the natural flake graphite and binder, it is fast thermal conductivity, high temperature resistance, thermal stability, and does not react with melting of the advantages is the casting of non-ferrous metals. However, in an atmosphere of high temperature oxidation-use easily oxidized, in the provision of different heat sources should be avoided when the strong oxidative atmosphere, it will reduce its life.

Graphite crucible of

Graphite Crucible in raw materials, manufacturing, and other aspects are taken as far as possible means to satisfy the conditions under the cruel use.
Main characteristics listed below:

(1) Heat conduction: the use of a thermal conductivity higher raw materials such as graphite, which has shortened melt-down time;

(2) Heat shock: the impact of strong heat-resistant, thermal quench urgency, it is not easy rupture;

(3) High heat resistance: refractoriness, is resistant to high temperature of 1200 ~ 1600 ?滠

(4) Anti-erosion: the fight against the erosion of the melting-soup;

(5) Anti-mechanical shocks: a certain degree of the impact of anti-mechanical strength (melting material inputs, etc.);

(6) Oxidation resistance: graphite oxide aerosol in the high temperature oxidation easy, as a treatment to prevent oxidation, and oxidation consume less;

(7) Anti-adhesion: Graphite is not easy because with the melting-adhesion properties of the melt-immersion and viscosity of less;

(8) Metal pollution in very little: because there is no pollution mixed with the melting-impurity, little metal pollution;

(9) Set slag resistance of (Cleaner agent) Impact: Set a good slag-resistant (Cleaner agents) affect performance.

Graphite Crucible use

Each graphite crucible people are imbued with the spirit of soul production out of a love should be used properly. As the use of the different methods, longer life expectancy, while others are short, it can be said that is a graphite crucible of life.

1) The correct positioning Bridgman method
2) The input method of melting materials

Materials should be the same as shown below, in the crucible into the vertical arrangement. Aluminum ingots skew contact with the crucible wall due to thermal expansion, Crucible occur pushed the possibility of rupture.

Melting after the soup in the scoop, please note that should not remain residual soup. The residue was solidified in the next soup when the melt-down is due to the rapid thermal expansion caused the breakdown of the reasons for Crucible.
The crucible of combustion, must pay attention to the furnace burner design and adjustment to the crucible and the crucible bottom Taiwan for complete combustion. As shown, according to the order ?٠~ ?ܠreddening material is the ideal. Heating, care should be taken not in the state of peroxidation, as far as possible in a short period of time for the rapid warming.
