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.
