Graphite Crucible
Our Graphite Crucible is the best solution to metallurgical operations for the heat resistance and the thermal stability of stability. It is refractory containers specially molded for metallurgical operations. The product is made of a mixture of Graphite, Refractory Clay, Grog and other additives. This Graphite Crucible is termed as clay bonded machine according to the raw materials used. It is available with or without spout. It is especially used for melting ferrous, non-ferrous metals alloys and noble metals.
Advantages:
1) Wth excellent electrical conductivity and high thermal conductivity
2) Only needs low thermal expansion, resulting in high thermal resistance
3) It is a Graphite Crucible well-functioned under high temperatures
4) Making chemical inertness and non-wetting to metals
5) Equipped with qualified machinability
With 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 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:
Heat conduction: the use of a thermal conductivity higher raw materials such as graphite, which has shortened melt-down time;
Heat shock: the impact of strong heat-resistant, thermal quench urgency, it is not easy rupture;
The Graphite Crucible is high-heat resisted: refractoriness, is resistant to high temperature of 1200 ~ 1600 ℃
Anti-erosion: the fight against the erosion of the melting-soup;
Anti-mechanical shocks: a certain degree of the impact of anti-mechanical strength (melting material inputs, etc.);
Oxidation resistance: graphite oxide aerosol in the high temperature oxidation easy, as a treatment to prevent oxidation, and oxidation consume less;
Anti-adhesion: it is not easy to produce because of the melting-adhesion properties of the melt-immersion and viscosity of less;
Metal pollution in very little: because there is no pollution mixed with the melting-impurity, little metal pollution;
Set slag resistance of (Cleaner agent) Impact: Set a good slag-resistant (Cleaner agents) affect performance.
Graphite Crucible use
Each items 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 product of life.
1) The correct positioning Bridgman method
2) The input method of melting materials
Materials of the item should be the same as shown below, in the crucible into the vertical arrangement. Aluminum ingots skew contact with the wall due to thermal expansion, and it occurs 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 Graphite Crucible.
The combustion must pay attention to the furnace burner design and adjustment to the bottom for complete combustion. As shown, according to the order, reddening 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. Our product is your best choice.
