一、未来的喷煤高炉 1982年美国钢铁协会在一篇讨论直接还原法经济效益的文章中(Ironmaking and Steel making 1982 Vol、9 №3 Davis CG,Mc Farlin JF,PrattHR)披露了其所设想的“未来富氧喷煤高炉”技术。1985年奥钢铁、西德考夫在南非主要钢铁厂参加之下,试验成功了熔融还原炼铁工艺,并决定在南非艾斯科钢铁厂建立第一台设计能力30万吨铁水/年的工业生产装置。两种工艺的主要参数和经济指标见表1和表2。
I. The Future Blast Furnace In 1982, the American Iron and Steel Institute disclosed in an article discussing the economic benefits of direct reduction (1982: 9, No. 3 Davis CG, McFarlin JF, PrattHR) “Future oxygen-rich coal blast furnace” technology. 1985 Austrian Iron and Steel Company, West Germany Kraft joined the major steelworks in South Africa, the successful trial of the smelting reduction ironmaking process, and decided to set up in South Africa’s Ascot Steel Plant first design capacity of 300,000 tons of hot metal / year industry Production equipment. The two main parameters of the process and economic indicators in Table 1 and Table 2.
