One approach to reduce CO2 emission in the steelmaking industry is to recycle scrap to the blast furnace/basic oxygen furnace (BF/BOF) production system. This paper performed a numerical investigation on the BF operation with scrap charging. The investigated BF was with an inner volume of 820 m3. producing 2950 tons of hot metal per day (tHM/d). https://www.nacrack.com/hot-savings-Almond-White-Rib-Knit-Set-p8926-mega-pick/
