摘要: 测定了攀西地区混合煤的理化性能, 并在攀钢高炉上进行了喷吹混合煤的工业性试验, 瘦煤配比由 10%逐渐增加到 25%, 煤比达到 113.81kg/tFe;2000年上半年瘦煤配比平均为 35.00%, 煤比达到 139.14kg/tFe。Abstract: Physical chemistry properties of various mixing coals in Panxi area has been measured and the industrial-scale experiment on injection of mixing pulverized coals into blast furnace has been carried out in PZH Steel.Burden ratio of lean coal is increased gradually from 10% to 25% with the result of 113.81kg/tFe coal ratio.Coal ratio of 139.14 kg/tFe has been reached with an average mixing ratio of 35.00% lean coal in the first half year of 2000.
