 · According to the steel production process various slag types can be produced. Steel slag is produced during the conversion of hot metal to crude steel in a basic oxygen furnace BOF or during the melting of scrap in an electric arc furnace EAF . Additional steel slag types are formed during secondary metallurgical process see Fig.1. For the carbon steel production non-alloyed steel scrap is used as input material. In contrast for the stainless steel production low- or high alloyed steel scrap is used along with the fluxes (e.g. lime stone and/or dolomite) to give the crude steel the required chemical composition. Then the slag floats on top of the molten bath of steel. The liquid slag is water cooled at temperatures around 1600 °C. Slag then allowed to slowly air- cool forming aggregate shape slag
