What is the purpose of limestone in a blast furnace? - Quora

 · Limestone is the reducing agent, without limestone the iron ore i.e Fe2O3 will never get reduced to Pig iron i.e Fe .. "calcination" should be lesser inside the blast furnace to reduce the coke rate that's why sinter is being used nowadays, as in sintering process limestone is calcinised outside the furnace which reduces the coke rate by 5–8%.
