The temperature of the pig iron melt rises from 1250 °C to over 1600 °C. For this reason, approx. 20 % iron scrap is added for cooling in order to protect the converter lined with stones from excessive temperatures. Iron ore or sponge iron (from the direct reduced iron process) can also be used for cooling.

The primary difference between Sponge Iron vs Pig Iron lies in their production process, composition, and properties. Sponge Iron is a purer form of iron with a lower carbon content compared to Pig Iron. It has a higher melting point, greater resistance to oxidation, and is more malleable and ductile. Pig Iron, on the other hand, is more ...

The production of sponge iron begins with the direct reduction of iron ore. In traditional iron-making processes like the blast furnace, iron ore is smelted to obtain pig iron, which is high in carbon content. However, in the case of sponge iron, the direct reduction process eliminates the carbon content, resulting in metallic iron.
