equipments to convert iron ore to pig iron

Creating Steel | HowStuffWorks

The advantage of steel over iron is greatly improved strength. 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.
