The paper presents a study of the electric arc furnace who using Carbon-Jet and Oxygen-Jet to reduce specific consumption of energy. Electric arc furnaces (EAF) play an important and increasing role in modern steel work concepts. The ability to precisely control the temperature and chemistry of the batch make EAF an ideal choice for producing high-grade steel for the recycling of scrap. Of the steel made today 36% is produced by the EAF route and this share will increase to 50 by 2030. The EAF has been studied for many years, but it is still difficult to complete representation.

Demands for increased steel production and rules for network disturbances have, together with increasing cost of energy, made reactive power compensation a profitable solution in the steel industry. A modern and cost efficient steel melting process demands a stable and steady voltage support for the Electric Arc Furnace. With dynamic reactive power compensation, the random voltage variations characterized by an arc furnace are minimized. The minimized voltage variations are achieved by continuously compensating the reactive power consumption from the arc furnace. [ABSTRACT FROM AUTHOR]

This paper presents a study of electric arc furnace with an new powerful electric transformer. Electric arc furnaces type UHP requires large electrical power so they are modified from conventional ovens. In this case melting and refining are done with a single oxidant slag. Deoxidizing and alloying are done outside the electric arc furnace in the ladle furnace. This technology greatly increases productivity and lowers furnace specific materials and energy consumption. Increasing power transformer requires many changes. With increasing electric arc furnace productivity increased and extreme fluctuation of voltage, flicker, harmonics and imbalance between phases.
