Electric arc furnace - Wikipedia
An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc.. Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundries for producing cast iron products) up to about 400-tonne units used for secondary steelmaking.Arc furnaces used in research laboratories and by dentists may have a capacityElectric Arc Furnace Process - an overview | ScienceDirect,,Electric Arc Furnace Process. In the electric arc furnace process, the electric arc furnace oxidizing slag is firstly produced when the iron scrap is melted and refined into steel, and then the electric arc furnace reducing slag is produced in the ladle refining furnace. From: Carbon Dioxide Sequestration in Cementitious Construction Materials,Steel Slag - an overview | ScienceDirect Topics,Depending on the used production technology, the steel slag can be divided into a basic oxygen steel slag, an electric arc furnace slag and a ladle furnace slag (De Brito and Saika, 2013). The steel slag is used as a secondary cementitious binder, or aggregates for road construction (Sheen et al., 2013; Manso et al., 2004).Slag - Wikipedia,Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be furtherMineral Admixtures used in Concrete and Their, - Happho,Blast furnace slag is a by-product of iron extraction process from iron ore. Amongst all mineral admixtures, blast furnace slag has the highest specific gravity (2.8 to 3.0). Typically, the slag fineness is slightly more than that of the cement.Fly Ash, Slag, Silica Fume, and Natural Pozzolans,,ground granulated blast furnace slag and ACI 233 (1995) provides an extensive review of slag. SILICA FUME Silica fume, also referred to as microsilica or condensed silica fume, is a byproduct material that is used as a poz-zolan (Fig. 3-7). This byproduct is a result of the reduction of high-purity quartz with coal in an electric arc furnace in
How Steel Is Made | Metal Supermarkets
Jun 05, 2015· At the bottom of the furnace, temperatures reach over 3000 Fahrenheit. The molten slag floats on top of the molten steel, allowing it to be drained via a slag notch in the furnace. The molten steel is released from the hearth of the furnace through a tap hole.

The samples were ball milled and sifted by using a 25–50 μm mesh, to obtain a well-defined size interval of slag particles to be used for the experimental trials.
