1 酒钢炼铁概况酒钢原有两座高炉,1号高炉1513m~3,2号高炉750m~3,设计能力分别为:80万t/a、40万t/a。酒钢铁矿资源主要依靠自营矿山——镜铁山矿、黑鹰山块矿,占总用量的95%,其余为周边地区的杂矿,属于复合型矿。精矿品位低,SiO_2、K、Na、Ba含量高,冶炼难度大;1997年入炉品位只有49.7%,比1996年下降0.23%,且焦炭质量差,灰分高;面对这些困难,酒钢的炼铁工作者不怕困难,勇于进取,开展技术攻关,大胆探索高炉稳定顺行、高产、长寿、优质、低耗的新路子,推动了酒钢炼铁生产技术的不断进步,为公司的
1 Overview of Jiuhua Ironmaking Jiuquan’s original two blast furnaces, No. 1 blast furnace 1513m ~ 3, No. 2 blast furnace 750m ~ 3, design capacity were: 800000 t / a, 400000 t / a. Iron ore resources mainly rely on iron ore mine - mirror Iron Mountain, Black Hawk Block lump ore, accounting for 95% of the total amount, the rest of the surrounding area of the miscellaneous ore, are complex type ore. Concentrate low grade, high content of SiO_2, K, Na, Ba, smelting difficult; in 1997, only 49.7% of the grade into the furnace, down 0.23% over 1996, and poor coke quality, high ash content; in the face of these difficulties, Ironmaking workers are not afraid of difficulties, the courage to forge ahead, to carry out technical research, boldly explore the blast furnace stable and efficient, high yield, longevity, high quality and low consumption of new ways to promote the Jiuquan Iron and Steel production technology for continuous improvement for the company’s
