    Modeling of Three Phase Electric Arc Furnaces. Manuela PĂNOIU, Caius PĂNOIU and Ioan ŞORA. Abstract. In this paper are study the modeling of a three phase electric arc furnace installation. It is well know that the electric arc is a nonlinear element. Thus, for modeling his behavior, the authors are using aFile Size: 1MB. Mathematical Modeling and Experimental Validation of an Electric Arc Furnace Vito LOGAR, Dejan DOVZˇ AN and Igor Sˇ KRJANC Laboratory of Modeling, Simulation and Control Faculty of Electrical Engineering, University of Ljubljana, Trzˇasˇka 25, SI Ljubljana, Slovenia. E .

    A complete mathematical modeling of the electric arc furnace is proposed by Logar et al., 12) that integrates relevant concepts like the Cassie-Mayr modeling with the arc reactance model proposed by Köhle and also incorporating a function adding chaotic behavior to the voltage-current relation of the arc, their research work reproduces in a Cited by: 4. Electric arc furnace is using electricity as the fuel source, and utilizes the arc high temperature produced by electrode and furnace charge to heat and melts the furnace charge. It is widely using in the production of normal steel, high-quality carbon steel, various alloy steel, stainless, various ferroalloys.

      The electric arc furnace is more modern than the former and produces its product using scrap steel material, which is tossed into the furnace with the help of a large crane. A lid containing electrodes is then placed on top of and lowered into the furnace, where they conduct an electric current which takes the shape on an arc. Electric Arc Furnaces (EAFs) are a central part of the production route that is an alternative to the dominant BF-BOF route. EAFs are used to produce carbon steels and alloy steels primarily by recycling ferrous scrap. In an EAF scrap and/or manufactured iron units – such as DRI, pig iron, iron carbide – is melted and converted into high quality steel by using high-power electric arcs.
