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 ...
Iron Ore Sinter – IspatGuru
Iron ore sinter or simply called sinter is usually the major component of a blast furnace iron bearing burden material. Sinter normally consists of various mineral phases produced by sintering of iron ore fines with fluxes, metallurgical wastes and a solid fuel. Coke breeze is normally used as fuel in the sinter mix since it supplies necessary heat energy for sintering of sinter mix. Fig 1 shows a piece of sinter.
