Graphite electrodes are an essential component of electric arc furnaces used in steelmaking, aluminum production, and other industrial processes. They are made from high-purity graphite, a form of carbon, and are used to conduct electricity in the furnace. Graphite electrodes are highly conductive and can withstand extremely high temperatures, making them ideal for use in the intense heat of electric arc furnaces.
Graphite electrodes are composed of a carbon core surrounded by a metal sheath. The core is made from high-purity graphite, which is a form of carbon that is highly conductive and can withstand extremely high temperatures. The metal sheath is usually made from copper, nickel, or stainless steel and serves to protect the graphite core from damage.
Graphite electrodes are used in electric arc furnaces to conduct electricity and create an arc of intense heat. This arc is used to melt and refine metals such as steel and aluminum. Graphite electrodes are also used in other industrial processes such as smelting, welding, and cutting.
