calcination of lime stone in blast furnace

  • Calcination - an overview ScienceDirect Topics

    According to a rough estimate by Biswas [27], for every 100-kg limestone charged to the blast furnace, the coke rate increases by approximately 25–35 kg/THM. Therefore, fluxing of the iron ore (using prefluxed sinters and pellets) and calcination of limestone outside the blast furnace is preferred to avoid extra consumption of coke.
