magnet, thickness of slag layer, regrinding of coarse grains, and moisture content. 3. Experimental Material Characterization The material used in the current research was slag from electricarc 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
Keywords: Electric arc furnace, EAF, electromagnetic stirring, CFD, flow modeling Abstract Electromagnetic stirring can play an important role in modern Electric Arc Furnaces (EAF), as they often operate far from equilibrium conditions, with taptotap times of 45 minutes or less, high electric power input and significant
In the electric arc furnace, steel is produced only through scrap fusion. Scraps, direct reduced iron, pig iron, and additives are melted through highpower electric arcs formed between a cathode
Steelmaking slag consists of converter slag that is generated by converter and electric arc furnace slag that is generated during the electric arc furnace steelmaking process that uses steelscrap as the raw material. Characteristics of iron/steel slag The typical compositions of iron/steel slag

electric arc furnaces. magnetic separation. The first stage of slag processing is crushing and sc reening the feed material to fractions of 04 and 422 mm. Coarser fractio ns are handled by a heavy media separation the DWPmethod. A magnet separator and spiral washing are
#0183;#32;Electric arc furnace (EAF) slag is a byproduct 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 cementbased materials, due to its good physical, chemical and mineralogical properties. Particularly the reuse as coarse aggregate for concrete production has been shown to

#0183;#32;The steelmaking slag fines can include desulfurization (DeS) slag fines, basic oxygen furnace (BOF) slag fines, electric arc furnace (EAF) slag fines and ladle metallurgy furnace (LMF) slag fines. Low iron grades, high impurity concentrations and inappropriate particle sizes are major barriers for recycling of the steelmaking slag fines back into ironmaking and steelmaking processes.
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 (, 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 nonmetallic scrap components and []
During the pyrometallurgical treatment of the nickelbearing laterite in the plant of LARCO, slag is produced after treatment in electricarc furnace (EAF) that contains to % Ni.
