Use of graphite products----as conductive material

The use of graphite products is much higher than we expected, so what are the uses of graphite products we know so far?

Used as a conductive material

When smelting various alloy steels and ferroalloys or producing calcium carbide (calcium carbide) and yellow phosphorus in electric arc furnace or submerged electric furnace, a strong current is introduced through carbon electrodes (or continuous self-baking electrodes—that is, electrode paste) or graphitized electrodes The smelting zone of the electric furnace generates an arc, which converts electric energy into heat energy, and the temperature rises to about 2000 degrees Celsius, so as to meet the requirements of smelting or reaction. Metal magnesium, aluminum, and sodium are generally prepared by molten salt electrolysis. At this time, the anode conductive materials of the electrolytic cell are graphitized electrodes or continuous self-baking electrodes (anode paste, sometimes prebaked anodes). The temperature of molten salt electrolysis is generally below 1000 degrees Celsius. The anode conductive material of the salt solution electrolytic cell producing caustic soda (sodium hydroxide) and chlorine gas generally uses a graphitized anode. The conductive material of the furnace head of the resistance furnace used in the production of corundum (silicon carbide) also uses graphitized electrodes. In addition to the above uses, carbon and graphite products are widely used as conductive materials in the motor manufacturing industry as slip rings and brushes, and also as carbon rods in dry batteries, arc carbon rods for searchlights or arcs, and anodes in mercury rectifiers Wait.
