7 advantages of electric arc furnace

Electric arc furnaces use electric energy as their main energy source. Electric energy is arc drawn through the discharge of graphite electrodes and the charge to produce high temperatures above 2000 ~ 6000 ℃, and the scrap steel raw materials are melted by means of arc radiation, temperature convec

Electric arc furnace's development history

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.
