10余年来,冶金工业节能技术进步取得了很大的成绩,使技术节能量占全行业总节能量的比重由最初的20%提高到“七五”末的40%左右,为实现全行业节能目标,保证冶金工业持续发展起到了重要作用。“六五”期间,冶金工业重点推广了煤气回收、低碳厚料层烧结、高炉喷吹煤粉,平炉吹氧、连铸机、炉窑节能改造、余热回收发电等30项节能技术。
Over the past 10 years, the metallurgical industry has made great achievements in energy-saving technological advancement, making the proportion of technological energy-savings in the total energy-saving capacity of the industry increase from the initial 20% to about 40% of the end of the “Seven-Five-year Plan”, to realize the The goal of energy conservation in the industry has played an important role in ensuring the continued development of the metallurgical industry. During the “6th Five-Year Plan” period, the metallurgical industry focused on the promotion of 30 energy-saving technologies such as gas recovery, low carbon thick layer sintering, blast furnace pulverized coal injection, open hearth furnace oxygen blowing, caster, energy-saving furnace reform, and waste heat recovery power generation. .
