Energy Use in US Steel Manufacturing

Energy Use in US Steel Manufacturing The blast furnace burns the coke to heat the iron ore causing it to react into iron (Fe 2), nitrogen (N 2), and carbon dioxide (CO 2). This iron is often known as "pig iron" or "hot metal" as it is a liquid iron that flows from the bottom of the blast furnace. This iron can be used for ironworks or as the starting material for creating steel.
