攀钢 3号高炉利用系数已稳定地突破 2 .0 ,1999年 11月曾创造了 2 .42 5的好水平 ,表明我国钒钛磁铁高炉冶炼技术获得重大突破。攀钢钒钛磁铁矿曾被国外专家视为世界上最差的原料。在炼铁厂投期初期 ,经常出现一系列技术难题 ,使生产处于低水平徘徊的艰难境地。近年来 ,攀钢成? Panzhihua Iron and Steel No. 3 blast furnace utilization factor has been a steady breakthrough 2.0, in November 1999 had created a good level of 2.42 5, indicating that China’s vanadium-titanium magnet blast furnace smelting technology has made a major breakthrough. Panzhihua vanadium titanomagnetite has been regarded as the world’s worst raw materials by foreign experts. In the early days of the ironworks, there often appeared a series of technical problems that kept production at a low level and hovering hard. In recent years, Panzhihua into?
