【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.更多还原
