This process is experimental and the keywords may be updated as the learning algorithm improves. These keywords were added by machine and not by the authors. Electrical circuit specifics of modern EAFs, optimum electrical mode of the heat, DC furnaces, and problems of electrical energy supply are discussed as well. For operation an Electric Arc Furnace, we can observe some advantages and disadvantages for this type of process: Advantages Capabable of producing the full range of steel grades Not dependent on. The history of EAF steel making is advanced by continuous improvements in efciency and productivity, and it is able to make tailor made slag during the extended rening period by well-controlled production process. The following innovations are analyzed in detail: increase in power of EAF transformers up to 1.0 – 1.5 MVA/t implementing the secondary ladle metallurgy intensive oxygen and carbon injection into a bath slag foaming furnace operation with hot hill single scrap charging using hot metal continuous charging and melting of scrap in the liquid bath, etc. The electric arc furnace (EAF) was rst commercially introduced in 1899. Due to numerous innovations implemented during the last decades, hourly furnace productivity has been increased by 6 times, electrical energy consumption has been decreased by approximately 1.8 times, and electrode consumption reduced by 6 times. Increasе in productivity is the most important direction in EAF development. A negative effect of existing contradictory practice is the forming in prices for scrap, iron, electrical energy, and natural gas on general technological progress in steelmaking. It is a page of the detail of Electric arc furnace of Steel Plantech.Design, manufacturing, installation, sales and after-sales servicing of steelmaking. The change in these requirements with developing of current steel production. Process, ecological, economic, health, and safety requirements in steelmaking units.
