近日 ,攀钢历经六年自主开发的科技攻关项目 :“钢铁钒钛磁铁矿高炉强化冶炼新技术”荣获国家科技进步一等奖。该技术开创了国内外用普遍大型高炉冶炼低入炉品位的特殊矿达到高利用系数的先河。依靠该技术 ,攀钢在入炉品位仅 46%的条件下 ,使高炉利用系数实现跨越性的优化 :1 9 Recently, Panzhihua Iron and Steel after six years of independent research and development projects: “Steel vanadium titanium magnetite blast furnace smelting new technology” won the first prize of national scientific and technological progress. The technology pioneered the widespread use of large and medium-sized blast furnace at home and abroad to reach the low utilization of special grade ore utilization factor precedent. Relying on this technology, Panzhihua Iron and Steel Co., Ltd. under the conditions of only 46% into the furnace grade, the blast furnace utilization factor to achieve cross-optimization: 1 9
