Features: Electric furnace for smelting ore and metal at high temperature generated by electrode arc. When the gas discharge forms an arc, the energy is very concentrated, and the temperature of the arc zone n is above 8000℃. Regarding c smelting metal, electric arc furnaces are more flexible than o

Compared with silica bricks, high-alumina bricks are characterized by high refractoriness, good thermal shock resistance, and high
READ MOREElectric 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
READ MOREFrench 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.
