  • Iron ore slime as an alternate coolant in steelmaking

    Abstract This paper describes an attempt to utilize iron ore slime in basic oxygen steelmaking as a coolant (instead of lump iron ore). Prior to its use it is briquetted for ease of charging. The tests are carried out in a regular commercial basic oxygen steelmaking furnace (160 ton/batch and duration about 45 min). Substitution of lump ore (with slime briquette) in various tests has been
