Graphite carbon bar (graphite rod)
The graphite carbon rods (graphite rods) are often used for electro-heat in high-temperature vacuum furnaces and are widely used in the field of industrial heating. So, what's the principle of graphite carbon rods
I. Heating principles of graphite carbon rods
The principle of graphite carbon rods (graphite rods) heating is based on electro-retarded heat, and when electricity flows out of time, its internal carbon atoms impede the flow of electronics to create resistance, and the jh effect of resistance produces heat, thereby allowing energy conversion to achieve heating purposes。
Ii. Core characteristics of graphite carbon rods
High temperature tolerance: graphite carbon rods are excellent for high temperature tolerance. At high temperatures, graphite carbon rods can maintain stable structure and performance and are not susceptible to deformation or damage。
Thermal properties: the graphite carbon rods have excellentrmal properties, with heat coefficients that not only exceed metal materials such as steel, iron and lead, but even tend to insulation in high temperature environments, and this efficient heat is leading to a significant advantage in heating of graphite carbon rods。
Electrical conductivity: graphite carbon rods have a resistance factor of approximately 8-13 x 10-6 times m, 1/4 of stainless steel, and conductive performance is significant。
Mechanical performance: graphite carbon rods have a small thermal expansion factor, hot and cold are not fragile, and processing performance is excellent。
Chemical stability: graphite carbon rods are very resistant to most acids, alkalis and organic solvents at constant temperatures, are chemically stable and apply to corrosive media environments。
Iii. Graphite carbon rod applications
High-temperature equipment: graphite carbon rods are excellent for high temperature tolerance and are often used in industrial thermal treatment equipment such as vacuum furnaces, smelters, smelting furnaces, high-temperature mixing。
Electrodical material: graphite carbon rods are often used in electrolytic cells, electric arc furnaces, etc. Because of their good conductivity and ability to withstand strong currents during electrolysis。
Axle bearing seals: the graphite carbon rods also play an important role in the mechanical industry and are often used to prepare parts such as bearings, seals, etc。
Semiconductor industry: graphite carbon rods are still able to maintain good conductivity at high temperatures and are therefore often used in heating systems for equipment such as proliferation furnaces, sinterers, etc。
In short, understanding the heating of graphite carbon rods makes it easier to use the scene. In addition to the graphite carbon rods that are actually selected, we need to make reasonable selections based on actual needs and application of the scenes, while ensuring value for money while satisfying their performance。
