iron. For steel making, about 100 to 150 kg/tonnesteel converter slag is discharged, and this by-product contains not only the converter slag but also the slag generated during hot metal pretreatment. When scrap is used as the main raw material for steelmaking, about 120 kg/tonne-steel of electric arc furnace slag is generated.
