1. High temperature stability and heat resistance
Graphite material has a very high melting point (about 3652 ° C) and can withstand extremely high temperatures. The highest temperature of an electric furnace can reach around 2200 ° C, which allows graphite vacuum furnaces to operate stably in high-temperature environments.
The high heat resistance of graphite ensures efficient heating and cooling processes, making it suitable for various high-temperature processes.
2. Chemical stability and corrosion resistance
Graphite exhibits good chemical stability at both room temperature and high temperature, and can resist erosion and corrosion from various chemical substances.
In a vacuum environment, the oxidation resistance of graphite is further improved, which helps to extend the service life of graphite components.
Graphite has good corrosion resistance to many corrosive media and can maintain stable performance in harsh environments.
3. Thermal conductivity and heating efficiency
Graphite is a good conductor of heat, and its thermal conductivity is superior to many metal materials.
In a graphite vacuum furnace, graphite fittings can make the heating process more uniform, thereby improving sintering efficiency.
The good thermal conductivity of graphite accessories can also reduce heat loss and improve energy utilization efficiency.
4. Low coefficient of expansion and high precision
The thermal expansion coefficient of graphite is very low, and the size change of graphite fittings is very small during heating and cooling processes.
This ensures the stability and accuracy of the equipment, which is important for workpieces that require high-precision machining.
5. Multi functionality and wide applicability
Graphite accessories have multiple functions in vacuum furnaces, such as heating elements, insulation layers, support and fixing structures, etc.
Graphite is often used as insulation carbon felt, graphite scraper, heating rod, furnace bed, guide rail, guide nozzle and other accessories in vacuum furnaces.
These functions and applications enable graphite vacuum furnaces to meet the needs of various complex processes.
6. Energy conservation and environmental protection
Graphite accessories have good thermal conductivity and insulation performance, which can reduce heat loss, improve energy utilization efficiency, and achieve energy-saving effects.
Graphite is stable at high temperatures and does not easily produce harmful substances. Additionally, graphite components themselves are non radioactive and meet environmental requirements.
