Graphite Electrode

Introduction:
The main function of graphite electrodes is to conduct electricity when smelting metals in electric arc furnaces. As the proportion of global electric arc furnace smelting steel is increasing, the use of electric arc furnaces to smelt steel plates and other secondary forming steels is the main project that consumes graphite electrodes.
 
Application:
Graphite electrodes are also used in smelting furnaces for melting non-ferrous metals, ceramic products, and in the waste recycling industry.
