Abstract：XBG (the bosh gas index) is defined as bosh gas volume through the area of hearth, K is given as the ventilation resistance coefficient and its formula, with XBG and K can be used as an indication of the furnace condition and measure of strengthening BF smelting. Analysis of Shiheng Special Steel production data showed that the No.1 BF’s XBG is 68 m3/(min·m2) and the K is 16.2, the BF is the most stable;the No.3 BF’s XBG is 70 m3/(min·m2) and the K is 16, the BF is the best regular working. The K and XBG can be incorporated into the blast furnace curve, the on-line real time observation can be realized, and the judgment for BF condition is quantized.
