The production of graphite electrode plates follows a complex process that begins with carbonization of various raw materials including petroleum coke and coal tar pitch, followed by calcination and graphitization. The finished product has high thermal conductivity and electrical conductivity, and is an indispensable material in steelmaking.
Graphite electrode plates are processed from high-purity graphite and are an important part of electric arc furnaces used for steelmaking. This graphite sheet is used as a conductive material to transmit electricity through the furnace to melt the metal. Additionally, they play a vital role in regulating the temperature of the furnace by transferring heat from the metal to the electrode plates.
