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.
