将炉腹煤气量指数XBG定义为单位炉缸断面积上通过的炉腹煤气量并给出了透气阻力系数K的计算公式，XBG及K可以用作判断炉况的标志，衡量高炉强化冶炼的程度。石横特钢的生产数据分析表明，1#高炉XBG为68 m3/（min·m2）、K为16.2时，高炉炉况最为稳定；3#高炉XBG为70 m3/（min·m2）、K为在16时，炉况顺行最好。可将XBG、K并入高炉曲线，实现在线实时观察，对高炉炉况顺行状态判断实现量化。
將爐腹煤氣量指數XBG定義為單位爐缸斷麵積上通過的爐腹煤氣量併給齣瞭透氣阻力繫數K的計算公式，XBG及K可以用作判斷爐況的標誌，衡量高爐彊化冶煉的程度。石橫特鋼的生產數據分析錶明，1#高爐XBG為68 m3/（min·m2）、K為16.2時，高爐爐況最為穩定；3#高爐XBG為70 m3/（min·m2）、K為在16時，爐況順行最好。可將XBG、K併入高爐麯線，實現在線實時觀察，對高爐爐況順行狀態判斷實現量化。

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.
