Graphite rods and the difference between carbon graphite rods and the carbon rods of the main difference is that the material composition, manufacturing process and the chemical and physical properties: graphite rod made of graphitization treatment of carbon materials, resistant to high temperature and electrical conductivity is strong; Carbon rods are made of ungraphitized carbon materials, which have better chemical stability but lower hardness. Material composition and manufacturing process of graphite rod: raw materials for the natural graphite with a mixture of petroleum coke and pitch coke, the high temperature graphitization treatment (3000 ℃), carbon atoms are arranged in graphite crystal structure. 1 hard, high temperature (about 3850 ℃), melting point, excellent electrical conductivity and thermal conductivity. 23 carbon rod: made of carbon materials (such as carbon powder, binder) extrusion molding, sintering temperature is only about 1000 ℃, not through graphitization process, internal to the amorphous carbon structure. 14 hardness is low, but excellent chemical stability, resistance to acid and alkali corrosion. 4: effect on physical and chemical properties of graphite rods conductivity is stronger, is often used in electrodes (such as steel-making arc furnace); Carbon rods have relatively weak electrical conductivity, but they are suitable for arc cutting of metals. 3 high temperature resistance, graphite rod structure at high temperature stability, is suitable for smelting; Carbon rods have slightly inferior high-temperature resistance, but they can meet the needs of most industries. Mechanical properties: graphite rod brittle is higher; Carbon rods have better tensile strength, but they are fragile. 34 applications graphite rod: steel electrode, semiconductor hot field components, high temperature furnace heating elements. 2 elements: metal cutting, such as stainless steel, cast iron electrode, spectral analysis, chemical reactor lining.
