近年来,一些资本主义国家都把降低钢铁工业能耗作为重要课题。特别是日本,资源缺乏,所需能源主要靠进口,因而对降低钢铁工业能耗就更为注意,并取得显著效果。据新日铁统计,炼铁能源占钢铁工业总能耗的48％。炼铁消费的能量主要是燃料,因此各企业都大力降低燃料比,1979年1月,福山厂3016米~3的3高炉创造了燃料比428.2公斤/吨的新记录。日本近年来的燃料比如下:年1975 1976 1977 1978燃料比,公斤/吨492 479 472 470
In recent years, some capitalist countries have made reducing energy consumption in the iron and steel industry an important issue. Japan, in particular, lacks resources and relies mainly on imported energy. Therefore, it is paying more attention to reducing energy consumption in the iron and steel industry and has achieved remarkable results. According to Nippon Steel statistics, iron-making energy accounts for 48% of the total energy consumption of the steel industry. Ironmaking consumes mainly energy as fuel, so companies are reducing their fuel ratio. In January 1979, 3 blast furnaces at Fukuyama Plant of 3016m ~ 3 created a new record with a fuel ratio of 428.2kg / t. The fuel ratios of Japan in recent years are as follows: Year 1975 1976 1977 1978 Fuel Ratio, kg / tonne 492 479 472 470
