Abstract
This report reviews energy and environmental issues which are specific to the iron and steel industry. The intention has been to illustrate available options, short-term and long-term, for increasing efficiency, converting from one source of energy to another, introducing process improvements or even transferring to completely new processes. The Swedish steel industrys total current coal consumption is about 11 TWh per year. Current electricity consumption is about 4 TWh per year, while the industrys consumption of oil is about 1.8 TWh per year. LPG consumption is about 1.6 TWh per year. A simplified cost accounting model has been developed to illustrate the influence of the energy efficiency and environment-related costs. The conclusion is that, at current energy prices, electric furnaces would have to be extremely efficient to achieve energy costs (including environmental taxes) lower than those of efficient modern fuel-fired furnaces. The model has also been used to determine the consequences of a recently presented proposal from a government commission concerning the energy taxes imposed on industry. The proposed tax reductions would dramatically improve the competitiveness of oil as an energy source. The possibilities for generating electricity by utilizing process gases and waste heat are discussed. From the energy viewpoint,

The possibilities for generating electricity by utilizing process gases and waste heat are discussed. From the energy viewpoint, production of a total of 0.5 TWh of electricity is fully feasible for the integrated plants in Oxeloesund and Luleaa, without additional fuel consumption at the plants. A general review of the extremes likely to be reached by the iron and steel industry in terms of future electricity consumption reveals the following: Based on technical factors alone, it is fully possible that electricity consumption could be slashed by half, to a level of 2 TWh per year or, conversely, double to a level of 8 TWh a year. Actual development will be determined by factors other than the strictly technical. ( 60 refs., 10 tabs., 64 figs.).}
