Energy Use in US Steel Manufacturing

These reactions are endothermic and require energy input. For example, the reduction of iron ore to iron will require energy beyond simply heating the iron ore to complete. With an understanding of the energy required for each of the major subprocesses in steel production, we can now discuss how much energy is used to create a steel object.
