• Theoretical Study was made on the reasonable use of oxygen in the blast furnace to achieve both high productivity and low fuel rate with one dimensional blast furnace mathematical simulation model and following results were obtained.(1) There exist an optimum oxygen concentration and an optimum flame temperature and the increase of the oxygen concentration straightly results in the increases of fuel rate.(2) By the combined injection of pulverized coal with the increase of oxygen concentration to control the flame temperature at an optimum value of about 2100°C, both high productivity and low fuel rate can be achieved.
