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.
The slag granulation plant comprises three sections: for granulation, dewatering and storage. In the granulation section, the liquid slag is 'quenched' by pouring onto it an excess water stream. The evaporated water will be condensed in a condensing tower located above the granulation tank.
