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

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 ...

Electric Arc Furnace Processes
1997The electric arc furnace processing of oxide ceramics is a well-established and widely-used industrial technology. Raw materials are readily melted together by joule and radiant heating to form substantially large liquid volumes. These are refined if necessary with carbon and additions of metal scavenging agents such as iron, and the product is then ...

Electric Arc Behaviour in Steelmaking Arc Furnaces
DENKI-SEIKO[ELECTRIC FURNACE STEEL], 1967製鋼用アーク炉の生産性向上について,最近いろいろな研究が進められているが,基本的なアーク現象の研究は2, 3の報告がされているにすぎず,アーク炉のアーク,すなわち,大電流アーク現象については十分に解析されていないのが現状である。今回,小型3相アーク炉(容量100kgおよび2t)で,16mm高速度撮影装置を用いて毎秒3,000～4,000コマ/秒の速度で炉操業中のアークを撮影し,そのアーク現象を観察検討した結果,アーク現象に極性の影響が大きいこと,アークフレアが主に電極から生じているらしいこと,電極先端形状の相違によってアーク現象が大きく支配されることなどがわかった。また4'径電極では中空電極の効果が観察できた。

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.

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.
