Main applications of graphite electrodes
As an important carbon product, graphite electrodes play a role in conducting electricity and transferring heat in production. They are consumables on smelting equipment such as arc steelmaking furnaces, ore-heat furnaces, electric furnaces and resistance furnaces.
Graphite electrodes are widely used and are mainly used on various smelting equipment such as arc steelmaking furnaces, ore-heat furnaces, electric furnaces and resistance furnaces. As a conductive material, graphite electrodes play a vital role in the smelting process. In an arc steelmaking furnace, graphite electrodes generate high-temperature arcs through conduction to melt the charge and achieve the purpose of steelmaking. In ore-heat furnaces and electric furnaces, graphite electrodes are used to conduct current and generate heat energy to heat and melt the charge. In addition, graphite electrodes are also widely used in chemical, metallurgical, mechanical, electronic and other industrial fields.
