一、前言工业化国家钢铁工业的能源消费量约占一次能源消费总量的7.5％,占工业能源消费总量的18％到20％,日本的比重还要高。钢铁工业能耗比重高是由于钢铁的生产量大(世界每年的钢铁产量约7亿吨)和吨钢能耗高。这已成为许多会议所讨论的主题。1976年和1982年国 I. INTRODUCTION The energy consumption of the steel industry in industrialized countries accounts for about 7.5% of the total primary energy consumption and 18% to 20% of the total industrial energy consumption. Japan’s share is even higher. The high energy consumption in the steel industry is due to the large production of steel (about 700 million tons of steel is produced annually in the world) and high energy consumption per ton of steel. This has become the subject of many meetings. 1976 and 1982 countries
