04.04.2012· 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.

Slag recycling - recovery

Iron and steel slags are valuable raw materials that are obtained during the pig iron and crude steel production processes. Two main production methods are involved (Fig. 1). In the iron ore-based process, pig iron is produced from oxidic iron ores in a blast furnace. In an LD oxygen converter the molten pig iron is then processed together with steel scrap into crude steel…
