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.

The Valve Effect of an Electric ARC and Problems in Controlling Electric-ARC Furnaces
Metallurgist, 2015The reasons for the existence of constant components of current and voltage in electric-arc furnaces are examined. It is noted that the accuracy with which the constant component of arc voltage is evaluated is strongly affected by the method used to sample the voltage signal.

Electric welding by the carbon arc
Journal of the A.I.E.E., 1930This paper discusses the butt welding of steel sheets by the carbon arc process. It explains first that autogenous welding is divided into two main classes, viz., gas and electric; that electric arc welding is divided into two classes, viz., metallic and carbon arc. Gas and metallic arc welding in general require beveling of plates for butt welds while

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

An electric arc is formed when a current passes between two conductors through a non-conducting medium like air. Although the phenomenon was discovered during early electrical experiments and utilised widely in lighting by the end of the nineteenth century, its problems were not fully understood. First published in 1902, this book represents one of the

Physics Bulletin, 1960
By J. M. Somerville London : Methuen & Co. Ltd. Pp. ix + 150. Price 12s. 6d. The literature on arc discharges is notoriously scanty in spite of the fundamental and technical interest in such work. Apart from some excellent publications in German there are virtually no comprehensive publications on the subject.

Arcing Faults in Electrical Equipment
IEEE Transactions on Industry Applications, 2009Electrical incidents that result in significant injuries to people are often the result of substantially unconstrained free-burning arcing fault currents within electrical equipment. It is necessary to understand the nature of these arcs and be able to quantify the parameters before it is possible to really comprehend what is actually happening inside ...

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.

Publisher Summary This chapter discusses the electric arcs. Electric arcs are widely used for the study of atomic constants and parameters. Principally the strong radiation and the fact that most arc sources are in the regime of local thermal equilibrium have made them important research tools in quantitative spectroscopy, specifically for the study ...
