Identification of the electric arc of a furnace
1997This study allows comparing two competitive modelling techniques to identify the electric arc dynamics of a furnace. The first technique relies on a linear kRX model whereas the second one relies on a non linear ARX model built from a MLP neural network.

Optimization of the Electric Arc Furnace Process
IEEE Transactions on Industrial Electronics, 2019This paper presents an electric arc furnace (EAF) optimization framework intended to define optimal control profiles for the EAF, in order to increase its efficiency and thus reduce the energy consumption. The framework aims to minimize controllable losses and to maximize energy transfer to the bath and, consequently, minimize the operational costs ...

The purpose of this chapter is to give an up-to-date description of the raw materials needed for electric arc steelmaking. Most important is a supply of iron, which may be obtained from two major sources, namely (i) steel and cast iron scrap and (ii) iron ore. Iron derived from ore may be produced either by direct reduction, in which case it is usually

Arc-Furnace Control by Regulex Exciters
Transactions of the American Institute of Electrical Engineers, 1943FOR a number of years prior to the present urgency for the production of high-quality steel, the development in control methods for electric-arc furnaces remained substantially stationary in this country. These devices were in the general form of vibrating regulators or contact-making ammeters which rapidly connected the electrode motors to and ...

Modeling of A Resistance Regulated ARC Furnace
IEEE Transactions on Power Apparatus and Systems, 1985An electric arc furnace is a load with a definite impact on the power system. Some of the impacts include harmonics, voltage flicker, and increased power system losses. The objective of this study was to develop a model for analysis of the electrical characteristics and electrical parameters affecting the behavior of an arc furnace load.

Optimal process in electric arc furnaces
2017 IEEE Industry Applications Society Annual Meeting, 2017Recorders provide information related to the “tap to tap” Arc Furnace's operation time. In this article, a heuristic analysis is performed for electric arc furnace operation. At a later stage of the investigation, an optimization of the operation is performed.

In this chapter, electric steelmaking is introduced with a short review: share, raw materials, operation, typical equipment, off-gas treatment, emissions. Electric-based steelmaking enjoys a much comfortable position than integrated classical blast furnace—oxygen steelmaking facilities, regarding greenhouse emissions.

Modeling of the Electric Arc Behavior of the Electric Arc Furnace
2013During the electric arc furnace operation appear disturbances, which can affect the other equipments that are connected to the same power network. So it is necessary to develop models for the electric arc which characterizes the electric arc behavior in order to identify methods and solutions through which the disturbances that appear in the power ...

Electric arc furnace model in distribution systems
2014 IEEE Industry Application Society Annual Meeting, 2014This paper presents a new technique to characterize electrical arc furnaces through the measurement of electric power, stationary and transient states, and the imbalance of these systems. The nonstationary behavior of the voltage and current signals in electric arc furnaces is considered, and analysis techniques of power quality in the time domain are ...

Rocking indirect arc electric furnaces
Electrical Engineering, 1934The electric furnace of the rocking type with indirect arc has been developed to the point where it may be used not only For the melting of nonferrous metals but also in the production of castings of various types of iron and steel. Accurate control of the process is possible.
