    Graphite electrodes grades, consumption and applications ...

    Graphite electrodes grades RP – Regular Power. HP – High Power. HD – High Density. UHP – Ultra High Power. SHP – Super High Power. Graphite electrode is a very significant conductive material in electric arc furnace (EAF) steelmaking, with low resistivity as well as withstand high temperature of EAF, as the melting point of graphite is around 3900℃, and scrap steel is 1700 ...

    DC ARC FURNACES – PAST, PRESENT, AND FUTURE

    DC Arc Furnace by Sir William Siemens The idea behind the (direct current) DC arc furnace has been around for a very long time. Its use for the bulk melting of metals dates back at least to 1878, when Sir William Siemens used a DC arc furnace with a vertical graphite cathode, with the arc transferred to the melt in contact with a

    Electric Arc Furnace – The Graphite Network

    Electric Arc Furnace – The Graphite Network

    Electric arc furnaces are usually used for melting scrap iron and steel. The process involves the use of a lined vessel that is fed with scrap and a three graphite rods are lowered, touching the surface. A high voltage electrical current is passed, which creates arcs and produce heat, melting the steel.

    AISI | Electric Arc Furnace Steelmaking

    a long arc (high voltage) tap can be used without fear of radiation damage to the roof. The long arc maximizes the transfer of power to the scrap and a liquid pool of metal will form in the furnace hearth At the start of melting the arc is erratic and unstable. Wide swings in current are observed accompanied by rapid movement of the electrodes.
