Operation of blast furnace with oxygen enriched blast can be generalized in three modes,such as blast with stable air flowrate,blast with stable gas flowrate in bosh and blast with stable pressure drop in BF.

Application of BF bosh gas index to evaluating the extent of BF combustion intensity;

It is suggested by the author that BF bosh gas index should be applied to evaluate BF combustion intensity in that the BF bosh gas index can better describe the nature of BF intensity and the effects of various factors on BF intensity during the smelting in BF.
