Graphite Electrodes
Graphite electrodes have a wide range of applications, mainly in various smelting equipment such as electric arc steelmaking furnaces, ore-smelting furnaces, electric furnaces, and resistance furnaces. As a conductive material, graphite electrodes play a crucial role in the smelting process. In electric arc steelmaking furnaces, graphite electrodes generate high-temperature arcs through conduction of electricity, melting the furnace charge and achieving the purpose of steelmaking. In ore-smelting furnaces and electric furnaces, graphite electrodes are used to conduct current and generate heat energy to heat and melt the furnace charge. In addition, graphite electrodes are also widely used in chemical, metallurgical, machinery, electronics, and other industrial fields.
The properties of graphite electrodes mainly include electrical conductivity, high-temperature resistance, thermal shock resistance, oxidation resistance, and mechanical strength. Firstly, graphite electrodes have excellent electrical conductivity, which can effectively transmit current and generate high-temperature arcs. Secondly, graphite electrodes have extremely high high-temperature resistance and can work stably for a long time in high-temperature environments.
