利用普通高炉冶炼高钛型钒钛磁铁矿是攀钢炼铁技术的一大特点。近几年来,攀钢在冶炼钒钛磁铁矿技术的认识上有了新的发展,使攀钢高炉冶炼高钛型钒钛磁铁矿的技术取得了长足进步,如采用合理的炉料结构,提高原料管理技术,大规模地进行原料筛分设备的技术改造,提高鼓风动能,改进装料制度和大力发展喷煤技术等。随着技术的不断进步,高炉技术经济指标明显改善,1999年,在入炉品位只有47.38％的条件下,高炉利用系数达到2.149,煤比达到113.81kg/t,入炉焦比降到473kg/t;2000年1季度,高炉利用系数达到2.293,煤比达到135.77kg/t,入炉焦比降到432kg/t。
The use of ordinary blast furnace smelting vanadium titanium titanium magnetite is a major feature of Panzhihua Iron and Steel Technology. In recent years, Panzhihua Iron and Steel smelting vanadium titanium magnetite technology has a new understanding of the development, so that Panzhihua blast furnace smelting high-titanium vanadium titanium magnetite technology has made great strides, such as the use of a reasonable charge structure, Improve raw material management technology, large-scale technical transformation of raw materials screening equipment, improve blast kinetic energy, improve the charging system and vigorously develop coal injection technology. With the continuous improvement of technology, the blast furnace technical and economic indicators have been significantly improved. In 1999, when the furnace grade was only 47.38%, the blast furnace utilization coefficient reached 2.149, the coal ratio reached 113.81kg / t, the coke ratio dropped to 473kg / t; In the first quarter of 2000, the blast furnace utilization coefficient reached 2.293, the coal ratio reached 135.77kg / t, and the coke ratio dropped to 432kg / t.
