Vitrification of electric arc furnace dusts
Waste Management, 2002Electric arc furnace baghouse dust (EAFD), a waste by-product of the steelmaking process, contains the elements that are volatilized from the charge during the melting (Cr, Pb, Zn, Cu and Cd). The results of leaching tests show that the concentration of these elements exceeds the regulatory limits.

Enhancement of Electric Arc Furnace Dust by Recycling to Electric Arc Furnace
Journal of Environmental Engineering, 2002Electric arc furnace (EAF) dust is a hazardous waste product of the steelmaking industry with a high concentration of heavy metals, especially Zn and Pb. Existing treatment processes are industrially viable only when the zinc content is sufficiently high. In this research we present an industrial-scale process to enhance EAF dust by recycling it to the

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 ...

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.

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.

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 ...

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 Slag Concrete
2016The aim of this section is to comprehensively investigate the possibility of substituting natural aggregates with Black/Oxidizing Electric Arc Furnace (EAF) slag, at high replacement ratios, to produce structural concrete. The properties of the slag are described in detail, in terms of chemical composition, mineralogy, microstructure and physical ...

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.

The 3-phase electric arc furnace
Electrical Engineering, 1933The 3-phase electric arc furnace has established itself definitely as an important industrial unit in the production of ferrous materials. With the efficiency of the arc furnace being increased, and with the overall cost of installation and operation now being comparable with that of an equivalent open hearth, an even more extensive application is ...
