The Basic Oxygen Furnace (BOF) used for steel production undergoes several important steps: Step 1: Iron ore and limestone are processed, dried, finely ground, and filtered during the sintering process. During this time, coal is also roasted in the furnace to produce pure coke. Step 2: The product from step 1 is then fed into the blast furnace ...
Steel slag is a byproduct of the steelmaking and steel refining processes. This paper provides an overview of the different types of steel slag that are generated from basic-oxygen-furnace (BOF) steelmaking, electric-arc-furnace (EAF) steelmaking, and ladle-furnace steel refining processes. The mineralogical and morphological …

Recognition of slag as a sustainable alternative to natural materials makes it an ecologically sound and economically intelligent use of this product. Characterization of EAF Steel Slag It'simportant to remember that slagisn'tslag, there are different types thatare produced depending on the manufacturing process. To ensure EAF slag is being ...
Abstract. Using the sessile drop approach, interfacial reactions taking place in the slag/carbon region were investigated at 1550°C in a horizontal tube furnace under inert atmosphere (1 L/min Ar). In this study, waste rubber tyres were blended with metallurgical coke, already used as injectant in electric arc furnace (EAF) steelmaking, in ...
Steel slag, originated in Electric Arc Furnaces (EAF) for continuous steel production, have stone-like appearance, black colour with small white agglomerations of calcium carbonate and high roughness; they can be generally classified into two different kinds [5]: (1) Black basic slag, with a lime content lower than 40%, resulting from the …
High yield of iron and dephosphorization efficiency are very important in electric arc furnace (EAF) operation. Even though various methods has been operated to increase iron recovery and dephosphorization efficiency, the suitable control of slag composition is one of dominant factors affecting them because thermodynamic driving …

In this research, EAF steel slag was used as aggregates and LFS as a supplementary cementitious material, for the development of concrete for five different …
In this scope, the effect of electric arc furnace (EAF) slag inclusion on the geotechnical properties of clay soils was evaluated within an experimental framework. …
The main challenge of the steel industry for the next decade is the steel production transformation process, starting in Europe. The CO 2 intensive blast furnace/basic oxygen furnace (BOF) route will be substituted by a combination of Direct Reduced Iron (DRI), based on natural gas, later on "green" hydrogen, with an Electric Arc Furnace (EAF) or …
In this research, EAF steel slag was used as aggregates and LFS as a supplementary cementitious material, for the development of concrete for five different products/appli …
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 …

The BET specific surface area (S BET) analysis of the EAF slag before carbonation was performed using nitrogen gas analysis adsorptive.The result shows S BET of the slag to be 1.2 m 2 /g, pore volume 0.99 cm³/g and pore size 203 nm Fig. 2 shows the N 2 adsorption–desorption and pore size distribution plots of the fresh EAF slag. …
Partial or complete replacement of soils by industry waste materials is becoming more prevalent due to its benefits including environmental considerations and improvements in engineering properties of soils. Geotechnical properties of EAF-slag-admixed soils are rarely studied in the literature, and beneficial outcomes are not well …
Steel slag, which is a by-product of steel industry, mainly refers to basic oxygen furnace slag (BOF-slag) and electric arc furnace slag (EAF-slag). BOF-slag originates from the further refining of iron in a basic oxygen furnace while EAF-slag is derived from melting recycled scrap in an electric arc furnace ( Barca et al., 2013 ).
The growth of electric arc furnace (EAF) steelmaking in North America has occurred mainly in the past 40 years due to low electricity prices, an abundance of steel scrap (especially near large population centers), and the development of mini and macro steel mills based on metal recycling. Scrap availability and price has made steel …
