How A Blast Furnace Works Consortium Steel Iron

How A Blast Furnace Works Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe 2 O 3) or Magnetite

Reducibility and reduction swelling behaviour of some iron

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 used to reduce iron oxides and melt the charge materials.
