Analisys of Electric Arc Furnace Slag
steel research international, 2012AbstractThe black slag produced during the melting process in electric arc furnace can be used as adjunct in the operation of land filling, building operation of road grounds, and production of concrete. Their use limitation is due to the presence of polluting chemical elements, including Cr, Ba, V, Mo, etc, that can be dangerous for human and ...

Electric Arc Furnace Slag in Concrete
Journal of Materials in Civil Engineering, 2004This paper describes the work carried out in laboratory to produce concrete with good properties using oxidizing electric arc furnace (EAF) slag as fine and coarse aggregate. To do this, the slag obtained in the steelmaking process must be crushed and stabilized. First, a suitable mortar must be made and tested.

Wasteless Joint Processing of Ladle Furnace and Electric Arc Furnace Slags
Steel in Translation, 2021The urgent problem regarding the depletion of mineral resources in ferrous metallurgy can be efficiently solved by a complex reuse of man-caused waste products. Such wastes are mostly presented by electric arc furnace (EAF) slag and ladle furnace (LF) slag. These two kinds of slag are not completely utilized.

New Geopolymers Based on Electric Arc Furnace Slag
Advances in Science and Technology, 2010Electric arc furnace slag (EAF-S), coming from a steel productive plant in Italy, has been used as new source for geopolymers synthesis. The slag has been geopolymerized alone and with different content of metakaolin (MK) with the aim to investigate if EAF-S content plays a role in geopolymerization process.

Phosphorus removal from wastewater using electric arc furnace slag aggregate
Environmental Technology, 2020Electric arc furnace (EAF) slag aggregate, a waste by-product of the steel industry, exhibited a high potential for phosphorus (P) removal and had attracted considerable attention. The main objectives of this study were to evaluate the performance of using EAF slag aggregate as an adsorbent for P removal and identify its P removal capacity. A series of

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 ...

Valorization of Electrical Arc Furnace Oxidizing Slag
2014Valorization of the electrical arc furnace oxidizing slag by coke was carried out by the reduction of iron oxide in the slag. Since the reduction of iron oxide by solid carbon is an endothermic reaction, supply of heat energy is required. In addition, slag has a low thermal conductivity; traditional fuel injection is not suitable for this reaction ...

Phosphorus removal by electric arc furnace steel slag and serpentinite
Water Research, 2006Electric arc furnace (EAF) steel slag and serpentinite were tested in columns either alone or mixed with limestone to determine their capacity to remove phosphorus (P) from a solution containing initially 20mg P/L (for 114 days) than 400mg P/L (for 21 days). EAF steel slag was nearly 100% efficient due to specific P adsorption onto metal hydroxides and

Metallurgical resource recovery from waste steelmaking slag from electric arc furnace
Environmental Technology, 2021Steel slag from an electric arc furnace (EAF) may contain significant amounts of oxides of valuable metals. The recovery of iron and other metals from the EAF slag using smelt-reduction process was studied with coal as the reductant. A pig iron phase with high carbon and a final slag depleted of the valuable metals were generated.
