Question

While adding the raw materials into the blast furnace for the extraction of iron, it is forgotten to mix limestone with the charge.

(a) Predict the result of this mistake 

(b) Give reason for this result. 

(c) Bessemer converter follows blast furnace in steel industry. Justify.

Answer 1

(a) Metal production and removal of impurities are not satisfactory.

(b) If limestone is not added, production of CO₂ and CaO, become poor-CaO is a flux to remove acidic impurity SiO₂ 

(c) Blast Furnace produces pig iron and is converted to cast iron on remitting this cast iron is used in Bessemer converter to produce steel. So blast furnace is followed by a Bessemer converter in a steel industry.
