Supply, Demand and Use of Energy in Iron and Steelmaking.

Following a presentation of the share of the steel industry in total energy consumption in comparison with the other consumer groups of certain countries and communities, the individual energy carriers and their shares in the total energy requirement for steel production are discussed. Then the energy requirement and the energy carriers for the usual processing techniques and the individual production stages are considered. It is shown that in the steel industry a higher degree of utilization of energy has been achieved, but still further possibilities for energy savings exist. Furthermore, the additional energy requirement due to the increasing quality level and degree of processing, as well as to rationalization and environmental protection measures, is indicated.
