limestone in pig iron process

Creating Iron HowStuffWorks

At this point, the liquid iron typically flows through a channel and into a bed of sand. Once it cools, this metal is known as pig iron. To create a ton of pig iron, you start with 2 tons (1.8 metric tons) of ore, 1 ton of coke (0.9 metric tons) and a half ton (0.45 metric tons) of limestone

CHEMICAL GRADE LIMESTONE Carmeuse

Our chemical grade limestone is used in the ironmaking process to produce the slag, which removes impurities from the iron ore while making liquid pig iron. Limestone is added to iron sinter and pellets to add flux and promote agglomeration in your products. Blast furnaces can add limestone directly to the burden to promote slag formation and protect the refractory.

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%.
