Abstract：The characteristic relationship between the air volume of 5 500 m3 blast furnace and the air volume of AV100- 17 fan was analyzed. After the arrangement and screening of the operation data of the blast furnace side and blower side for many years, a large number of reliable operational data were sorted out by considering various special conditions. According to the statistical analysis of the operation data, the variations of the air volume, air pressure, oxygen content, oxygen enrichment rate for blast furnace with the air volume, air pressure and release volume for the blower were obtained. Combined with the change of the performance curve and the actual performance curve of the fan, it was pointed out that the increase of the oxygen ratio in the blast furnace had a negative effect on the drift and the increase of the dispersion. Aiming at the analysis result, this paper gives a solution and method to solve the problem from the aspects of improving the precision operation and energy saving transformation were put forward.
