Use of Iron Ore Pellets in Blast Furnace Burden IspatGuru

Jun 13, 2014· Sinter, pellet and the calibrated lump ores are the three iron bearing metallics normally used in the blast furnace burden. Uses of all the three metallics in blast furnace burden can vary from zero to hundred percent with adjustment of the furnace parameters. These three metallics can be used in any combination of two metallics or three metallics.
