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 …
Production and Processing. An Electric arc furnace (EAF) produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current Lime added (as flux) combine with silicates and oxides to form liquid slag. EAF slag has a lower density than steel and therefore floats on top of the molten steel.
Therefore, in this project, an attempt was made to recycle electric arc furnace (EAF) slag waste, obtained from Malaysia's steel making industry, into ceramic tile via conventional powder compaction method.
The furnace is refractory lined, and scrap and iron reduced from iron ore are charged into the furnace. (Refractory material is heat-resistant and infusible at the highest temperature of the steelmaking process.) Carbon electrodes pass current through the scrap to the furnace lining which creates an arc that supplies heat.
EAF slag properties depend on the type of steel produced in the furnace, scrap composition, slag cooling method and rate, and further, weathering processes. Two …

Electric arc furnace oxidizing slag (EAFS) is a by-product of the steelmaking industry, generated after the melting and the preliminary acid refining of liquid steel. It is a stony material that is easy to crush for use as aggregate in concrete mixes. This study examines the long-term aging reactions of EAFS and its volumetric stability, to ...
This study aims to characterize and investigate properties of EAF slag waste obtained from Southern Steel Berhad, Penang (one of Malaysia's largest steel makers), prior to its recycling into valuable products.
Problem statement: Steel making slag from Electric Arc Furnace (EAF) is an abundant by-product in Malaysia steel making industry. It has potential to be used for heavy metal removal from ...
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 …

The electric arc furnace slag (EAFS) is a waste material generated from the steel making process. It is an attractive low cost yet effective material for the heavy metals removal, particularly manganese and copper removal in the …
The steel production generates approximately 10 % of electric arc furnace slag on the production of each ton of steel. In the view of environmental concerns and government regulations regarding slag disposal, alternate ways …
Electric Arc Furnace (EAF) is a steel making furnace, in which steel scrap is heated and melted by heat of electric arcs striking between the furnace electrodes and the metal bath. Two kinds of electric current may be used in Electric Arc Furnaces: direct (DC) and alternating (AC). Three-phase AC Electric Arc Furnaces with graphite …
Since steel is mainly produced through an electric arc furnace (EAF) in Malaysia, most of the recycling options reviewed in this paper focused on EAF slag and the strengths and weaknesses of each recycle option were outlined.
Electric arc furnace (EAF) steelmaking slags that had undergone magnetic separation were obtained from a local steelmaking plant, and the major chemical composition of the slag is shown in Table 1.
The major by-product, steel slag is derived from three primary sources namely blast furnace slag, electric arc furnace slag (EAFS), and ladle slag [ 1, [5], [6], [7] ]. In producing steel, the best device to melt the scrap is the electric arc furnace.
In this study, an investigation on the suitability of electric arc furnace (EAF) steel slag and copper mine tailings (CMT) as alternative asphalt paving materials is proposed. Laboratory tests to evaluate the performance of mixtures incorporating EAF steel slag and CMT were conducted.
Electric arc furnace (EAF) slag is one of the most common by-products in the steelmaking industry. Despite various efforts of using this waste, there is yet a clear indication of EAF slag being recycled into commercial ceramic products, and most EAF slag ended up being disposed of through landfilling.
