Graphite electrodes are mainly used in electric arc furnaces. Currently, it is the only product with high electrical conductivity and can continuously generate the extremely high heat required in electric arc furnaces. It can also be used in refining furnaces to smelt steel. According to quality indicators, it can be divided into 4 types: ultra-high power graphite electrode, quasi-ultra-high power graphite electrode, high power graphite electrode, and ordinary power graphite electrode.
