| Abstract: | The injection oxygen and pulverized coai into blast furnace for intensifying Ironmaking process is of tremendous profits. The results of the experimental study and production practices show that the coal / coke replace rate can be raised by injecting the bituminous coals into blast furnace, decreasing the ash content in coal, increasing the temperature of the hearth in blast furnace, improving utilized level of gas, and the combustion rate of pulverized coal can be raised by increasing blast temperature, using the oxygen-coal lance with high efficiency which can supplied full oxygen directly to blowpipe of blast furnace and intensify mixing between oxygen and pulverized coal, using dispensation technique of coals, adding combustion accelerative agent to pulverized coal. |
