production of slag used as aggregates
Iron and Steel Making Slag – Environmentally Responsible ...
The slag materials represented by the National Slag Association are generated in the Iron and Steel making process. Blast Furnace (BF) Slag is generated simultaneously with the production of iron on a blast furnace and Steel making Slag is a coproduct of the steel produced either in a Basic Oxygen Furnace (BOF) or Electric Arc Furnace (EAF).
