1951年美国钢铁公司威尔顿厂实行富氧鼓风以来的生产实践证明,高炉富氧鼓风是强化高炉冶炼的有效手段。它可以大幅度提高产量和降低焦比。因此,近年来国内外都得到迅速发展。日本1958年开始用氧,1965年富氧率0.2～0.4%,1973年达到2.11%。1974年以后,由于西方经济不景气影响,高炉开工率不足,高炉用氧量下降。尽管如此,在大型高炉上仍然广泛采用富氧操作。苏联在第九个五年计划期间,钢铁工业部门有三十多台制氧机投
In 1951, the practice of oxygen-enriched blasting at the Wilton Plant in the United States has proved that blast furnace oxygen-enriched blasting is an effective means of enhancing blast furnace smelting. It can significantly increase production and reduce coke ratio. Therefore, in recent years both at home and abroad have been rapidly developing. Japan began to use oxygen in 1958, oxygen enrichment rate was 0.2-2.4% in 1965 and 2.11% in 1973. After 1974, due to the economic downturn in the West, the operating rate of the blast furnace was insufficient, and the amount of oxygen consumed in the blast furnace decreased. Nonetheless, oxygen-rich operations are still widely used on large blast furnaces. During the Ninth Five-Year Plan, the Soviet Union had more than thirty oxygen generators in the steel industry
