Reducibility and reduction swelling behaviour of some iron

Iron ore pellets are used for the production of hot metal in blast furnaces and DRI/HBI in direct reduction processes. A blast furnace is a shaft furnace, which is charged with iron bearing materials (pellets, sinters and/or lump ore), reducing agents (metallurgical coke) and additives (limestone, quartz, BOF slag). Metallurgical coke and auxiliary reducing agents (coal, oil, natural gas) are
