Graphite Crucible
Features
Graphite block is a high-temperature refractory material with unique physical and chemical properties, which has many practical applications
1. Metallurgical field: Graphite blocks are commonly used as lining plates and electrodes in high-temperature furnaces, such as electric arc furnaces, blast furnaces, etc. It can withstand extremely high temperatures and strong acid and alkali corrosion, while also possessing excellent conductivity and thermal conductivity.
2. Chemical industry: Graphite blocks are also widely used in the chemical industry, such as manufacturing reactors, dryers, evaporators, and other equipment. It can withstand the corrosion of various chemical media and high-temperature and high-pressure environments, while possessing excellent thermal stability and thermal shock resistance
3. Electronics field: Graphite blocks are also one of the important materials for manufacturing electronic products, such as battery plates, semiconductor smelting, carbon fibers, etc. It has good conductivity and thermal conductivity, and can manufacture efficient and energy-saving electronic devices.
Graphite has many excellent properties: high temperature resistance, melting point 3800 degrees, boiling point 4000 degrees, good conductivity, corrosion resistance, acid and alkali resistance, and is a relatively stable substance in nature. So, graphite is an excellent material.
And graphite has the advantages of low resistance coefficient, high temperature resistance, corrosion resistance, good thermal shock resistance, conductivity, low thermal expansion coefficient, self-lubrication, and easy precision machining. It is an ideal inorganic non-metallic crucible vessel, single crystal furnace heater, electric discharge machining graphite, sintering mold, electron tube anode, metal coating, graphite crucible for semiconductor technology, graphite anode for emission electron tubes, thyristors, and mercury arc rectifiers Gate, etc.
The graphite blocks used in the production of graphite heat exchanger and graphite absorber equipment are called graphite heat exchange blocks and graphite absorption blocks. Generally speaking, the pores of the purchased graphite blocks contain a small amount of water, which needs to be dried first to evaporate. This process is carried out in an electric oven, with a temperature controlled within 350 ℃ and a drying time of about 1-2 hours. During drying, water vapor is mainly generated, and there is no other process waste gas generated. When manufacturing graphite heat exchangers The graphite absorber equipment plays an irreplaceable role in graphite equipment due to its high structural strength and good impact resistance due to the fact that the heat exchange block absorption block only bears pressure and is an integral structure without adhesive joints.
