Review of Scientific Instruments, 1958
Various optical systems are discussed with reference to their use with carbon arc image furnaces. A new optical system which employs two elliptical mirrors is described and shown to have numerous practical advantages. Using modifications of motion picture projection lamps, measurements have been made of carbon arc image furnaces ranging up to more than

IEEE Transactions on Industry Applications, 1977
A new development in plasma furnace technology in which by relatively simple modifications a more or less conventional arc furnace can be made to produce a long stable plasma flame is described. A very promising application of this technique is in the steel melting as well as in direct reduction of fine iron ore, waste oxides, flotation concentrates ...

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.

Rotating Regulator For Arc Furnaces
Transactions of the American Institute of Electrical Engineers, 1943Increased production of steel alloy for the war effort has brought about a wider use of electric-arc furnaces, and with this improvements have been made in automatic regulation of electrode position. The Rototrol regulator described in this paper is of the rotating type which controls electrode position as determined by response to current in the ...

Electronic regulator for arc furnaces
Electrical Engineering, 1944With the increased use of arc furnaces in the production of alloy steel, new interest has been aroused in both old and new methods of automatic regulation of electrode position. The regulator described in this paper is an electronic type which controls electrode position as determined by response to current in the electrode and voltage between the ...

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
