Electric arc furnaces used for smelting generally have three characteristic working stages:· At the beginning of the melting stage, the solid charge is melted and the energy demand is the largest· Initial refining and heating stage· During the refining period, the input energy at this stage only

French Heroult (P.L.T.Héroult) used the high temperature of the electric arc of the electrode to develop an alternative energy source for coal and invented the electric arc furnace for industrial direct smelting from 1888 to 1892. At first, the electric arc furnace was only used for the production of calcium carbide and ferroalloys. It was not until 1906 that it was developed for steelmaking, which enabled the economical and large-scale recycling of steel scrap.
