Steelmaking Slag An Overview Sciencedirect Topics

Apr 04 2012 D. Sichen in Fundamentals of Metallurgy 2005 9.5.1 Slagmetal mixing. In steelmaking slagmetal mixing is a very common phenomenon and it occurs due to the shear at the slagmetal 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 slagmetal reactions.
