Assessing the Effectiveness of Slag Foaming in Electric-Arc Furnaces
Metallurgist, 2018The crucial role of foamed slag in improving the effectiveness of the arc-furnace process is beyond any doubt. However, there is no consistent approach to the description of the slag foaming mechanism despite the wide application of this process in modern electric-arc furnaces. Aspects of assessing the effectiveness of slag foaming are considered.

Environmental Impacts of Asphalt Mixes with Electric Arc Furnace Steel Slag
Journal of Environmental Quality, 2011Electric arc furnace (EAF) steel slag can be used as an alternative high-quality material in road construction. Although asphalts with slag aggregates have been recognized as environmentally acceptable, there is a lack of data concerning the potential leaching of toxic Cr(VI) due to the highly alkaline media of EAF slag.

Journal of Building EngineeringValorization of electric arc furnace primary steelmaking slags for cement applications
Waste Management, 2015To produce supplementary cementitious materials from electric arc furnace (EAF) slags, FeO was reduced using a two-stage reduction process that included an Al-dross reduction reaction followed by direct carbon reduction. A decrease in FeO was observed on tapping after the first-stage reduction, and further reduction with a stirred carbon rod in the ...

Properties of concretes with Black/Oxidizing Electric Arc Furnace slag aggregate
Cement and Concrete Composites, 2013Abstract The aim of this work is to comprehensively investigate the possibility of partially substituting natural aggregates with Black/Oxidizing Electric Arc Furnace (EAF) slag in concrete production. Five recycled and one traditional mixes were produced to identify a convenient substitution ratio for the concrete.

CHARACTERIZATION OF ELECTRIC ARC FURNACE STEEL SLAG
2017Steel production steelworks results also in large amounts of steel slag as a byproduct. [1-4] The resulting slag can be applied in different branches of the industry, depending on its properties and composition, which are tailored to the specific application requirements by additional procedures. Thermal stability of slag depends on its composition and

Use of Electric Arc Furnace Slag for High Strength Concrete Production
Applied Mechanics and Materials, 2016In this paper the use of Electric Arc Furnace slag (EAF slag) for the production of High-Performances Concrete (HPC) is explored, as a fully replacement of the natural gravel. Several mixtures were produced, varying the water/cement ratio, the cement and the admixture content, with the aim of reaching a strength class between C50/60 and C60/75, and an ...

The dynamic control of the slag foaming operation in the electric arc furnace
Revue de Métallurgie, 1998The production of quality steels in modern EAF requires the presence of an adequate foamy slag during the refining phase. Today, the control of this essential operation is still based on the operator experience.Derived from the expertise gained previously in oxygen steelmaking, CRM has proposed an improved technique for EAF through the use of specific ...

Durability of Electric Arc Furnace slag concrete
2016Electric Arc Furnace slag (EAF) is a by-product of steel production in electric arc furnace. Its physical and mechanical properties make it a suitable material for producing heavyweight concrete. Its use seems adequate in many fields, and particularly they can be employed for coastal protection, both in onshore and offshore field applications ...
