Creating Steel | HowStuffWorks

The open-hearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an open-hearth furnace. It is heated to about 1,600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface. Impurities, including carbon, are oxidized and float out of the iron into the slag.

How to Manufacture Pig Iron: How Pig Iron is made?

(3) Sponge Iron Process: As the name implies, the spongy iron is obtained by the reduction of lumpy iron ore or iron ore pellets from the oxide form into the metallic state. The iron content of the product so obtained varies from 90% to 94% and the balance represents the traces of gangue and residual iron oxide.
