2020-5-15  The spongy iron produced in the reduction zone moves down slowly and melts in the fusion zone. At the lower hotter part, the main reaction is : FeO + C —-> Fe + CO. It dissolves some carbon, silicon, phosphorus and manganese and forms the lower layer at the base of furnace. The iron thus obtained is called pig iron and cast into variety of shapes.
