Basic Oxygen Furnace (BOF) and Electric Arc Furnace (EAF). Because iron in the steel slags is normally encountered in the form of steel (7–10 %), iron oxide and iron bearing minerals, the recovery of iron is achieved by crushing or grinding, screening and magnetic separation [17]. Similarly to iron …

Electric arc furnace slag is produced during the manufacture of crude steel by the electric arc furnace (EAF) process. In this process steel scrap with additions of fluxes (e.g., lime[stone] and/or dolomite) are heated to a liquid state by means of an electric current. During the melting process the fluxes combine with non-metallic scrap components and […]

01-10-2015· Electric arc furnace (EAF) slag is a by-product of steel production in electric arc furnaces. Several studies have tried to demonstrate its suitability in civil engineering application, such as in bituminous mixtures and cement-based materials, due to its good physical, chemical and mineralogical properties. Particularly the re-use as coarse aggregate for concrete production has been shown to ...

15-08-2015· Two types of crushed electric arc furnace slag (EAFS1 and EAFS2) were used in this study, as detailed in , supplied by two different steelmakers.Some images of EAFS1 (fresh and after long-term weathering) are shown in Fig. 1.Their global chemical composition and physical properties are detailed in the Table 1 and their grading followed the method described for the limestone aggregate.

Slag foaming has become an important and critical practice for the modern electric arc furnace (EAF) since a good foaming slag contributes considerable efficiency and other benefits to the process. The quality of the slag foaming is an important factor in the EAF steelmaking process since it ensures that the heat from the liquid bath is not lost through the EAF walls.

Material Characterization The material used in the current research was slag from electric-arc furnace (EAF). The initial weight of the sample was 40 kg. After successive sampling, two representative samples of about 3 kg each were obtained and used for mineralogical characterization, chemical and sieve analysis of the material, as well as for magnetic separation tests.

Electric arc furnace Wikipedia An electric arc furnace EAF is a furnace that heats charged material by means of an electric arc Industrial arc furnaces range in size from small units of approximately one ton capacity used in foundries for producing cast iron products up to about 400 ton units used for secondary steelmakingArc furnaces used in research laboratories and by dentists may ...

as only iron (steel) was recycled from the slag and the rest of it was mainly disposed of to landfills. Today, due to the ever increasing share of steel production in electric arc furnaces in the world, the steel mill slag becomes more and more important and it replaces blast furnace slag …
