Role of Slag in Converter Steelmaking IspatGuru

Aug 01, 2015 If the slag to steel mass ratio at the end of a converter blow varies within 0.08 to 0.1, the slag to steel volume ratio rises from almost zero in the beginning of the blow to 0.20/0.25 towards the end of the blow. In general, slag is considered to dampen metal ejections (spitting) and dust formation from the converter during the blow.

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.
