摘　　要：包钢3号高炉1994年4月1日停炉扩容改造,炉容由1800m^3扩大到2200m^3,高径比由2.695降至2.35,炉缸高度由3.4m增加到4.6m,属于矮胖炉型,为含氟矿冶炼创造了有利条件。1994年6月1日投产后高炉平均利用系数达1.81,冶炼强度达1.004。The No.3 BF of Baoteu I & S Co.was blown-off on April 1st,1994 inf order to be modernized with effective inner volume expansion from 1800m3 to 2200m3,height to diameter ratio reduction from 2.695 to 2.35,and hearth height increase from 3.4m to 4.6m.The hlast furnace has a low shaft and favoured the fluorine-bearing ore smelting.After blowing-in on June 1st,1994.The average productivity ratio of 1.81t/(m3·d),and the smelting intensity of 1.004t/(m3·d) have reached.
