我厂广大职工在省冶金局和厂党委的领导下,遵照毛主席关于“中国人民有志气,有能力,一定要在不远的将来,赶上和超过世界先进水平”的伟大教导,坚持自力更生,艰苦奋斗,勤俭建国的方针,从1964年开始先后在我厂84M~3高炉进行了喷吹白煤、重油和焦油。经过多年的生产实践与摸索,对小高炉喷吹不同的燃料有了一定的认识,在高炉冶炼中取得了良好的效果,代替了焦炭中的碳提供热量,降低了焦比,富化了炉内的还原气体,改善了间接还原。喷吹对炉缸有冷化作用,并使沿炉缸半径上的温度分布均匀,为高
Under the leadership of Provincial Metallurgical Bureau and Factory Party Committee, the vast majority of our factory workers follow the great teachings of Chairman Mao on “the Chinese people have ambition and ability, must catch up with and surpass the world’s advanced level in the near future” and insist on self-reliance , Hard work, diligence and thrift to build the country’s principle, from 1964 has been in our plant 84M ~ 3 blast furnace blowing white coal, heavy oil and tar. After many years of production practice and exploration, the blast furnace blasting different fuels have a certain understanding, achieved good results in blast furnace smelting, instead of coke in the carbon to provide heat, reduce the coke ratio, rich furnace The reducing gas inside improves the indirect reduction. The injection has a cooling effect on the hearth, and the temperature distribution along the radius of the hearth is uniform and high
