In this paper, an overview of the recent achievements and challenges of using steel slags (BOF, EAF and LF slag) as cement replacement (usually ground into powder form with the size of 400–500 m 2 /kg) and aggregate in cement concrete is presented. The results suggest that the cementitious ability of all steel slags in concrete is low and requires activation. For the incorporation of steel ...

Role of Slag in Converter Steelmaking – IspatGuru

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. If a converter is operated with a very low amount of slag ...
