PDF A Review of Granulation Process for Blast Furnace SlagPROPERTIES Euroslag

Blast furnace slag is the main byproduct in the ironmaking process which contains large amounts of sensible heat In addition it s the major raw material for cementThe content of iron Fe in blast furnace slag ABS/GBS is usually lower than 05 wt since it results from a reduction process In contrast to blast furnace slag basic oxygen furnace slag BOS and electric arc furnace EAF slag steel slags are generated in an oxidizing process and therefore have iron contents that are significantly higher
