世界各国钢铁工业每年消耗的能源在国民经济总能源消耗中一般占5～18％,而电弧炉炼钢又是钢铁工业中的用电大户。因此,在当今能源问题十分突出的情况下,以节电为主的节能,是从事电弧炉炼钢人员十分关注的课题。电弧炉的节能,总的包括两个方面,即提高热效率和回收部份能量。在提高热效率方面,从60年代以来,发展了超高功率电炉、强化吹氧助熔等超速熔化技术;电磁搅拌、喷射冶金等快速精炼技术,以及按照冶炼周
The energy consumed by the steel industry in each country in the world generally accounts for 5% to 18% of the total energy consumption of the national economy, and electric arc furnace steelmaking is also a major electricity consumer in the steel industry. Therefore, in today’s energy situation is very prominent circumstances, to save energy-based energy-saving, is engaged in arc furnace steel-making staff are very concerned about the issue. Energy-saving EAF, including two aspects of the total, that is, to improve thermal efficiency and recovery of some energy. In terms of improving thermal efficiency, since the 1960s, ultra-high-power electric furnaces have been developed to speed up the ultra-fast melting technology such as oxygen blowing and oxygen blowing; rapid refining technologies such as electromagnetic stirring and jet metallurgy,
