EAFS is produced in an Electric Arc Furnace. The slag is dark grey in colour and is characteristically harder than blast furnace slag (BFS). It has a density about 20 - 25% greater than basalt or BFS. It crushes to a cubical shape. EAFS in common with most steel slags, is subject to slight dimensional expansion until it fully hydrates.

Other advantages of the magnetic separation flowsheet over the gravity-based separation flowsheet are that wet drum magnetic machine is easy to operate and occupies smaller area than shaking table for the same throughput.

Steelmaking Process - an overview | ScienceDirect Topics

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).

Steelmaking Slag - an overview | ScienceDirect Topics

Apr 04, 2012· D. Sichen, in Fundamentals of Metallurgy, 2005. 9.5.1 Slag–metal mixing. In steelmaking, slag–metal mixing is a very common phenomenon and it occurs due to the shear at the slag–metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which increases the total interfacial area and consequently the rate of slag–metal reactions.
