脱石油―オイルレス製鉄所をめざし―

抄録

Since the first oil-crisis of 1973, The Japanese Steel Industry has taken many efforts to achieve conservation of energy and oil.In this paper, procedures of steel production, energy consumption and technology of energy conservation are described along with future themes for energy and oil conservation.
Since the second oil crisis of 1979, almost all blast furnaces of integrated steel works stopped using oil for injection and, as a result, the percentage of coal-related energy of all consumed energy increased to about 90% form 70% in 1973.
In all steel works of Japan, consumption of oil-related energy decreased form 15 million kl in 1973 to 6 million in 1980 (estimate).
