1 前言由于具有投资省,风温高的显著优点,球式热风炉从70’年代开始在我国的小高炉上成功使用后就迅速得到推广。从1987年成钢300m~3级高炉采用球式热风炉至今,相继有威(远)钢、涟钢、汉钢、南昌钢厂等300m~3级高炉采用了球式热风炉。据资料统计,风温在1050～1150℃,最高达1200℃(短时间);但
1 Introduction Due to the significant advantages of investment saving and high air temperature, the ball type hot blast stove has been rapidly popularized since its successful use in our country’s small blast furnace in the 1970s. From 1987 Chenggang 300m ~ 3 blast furnace with a ball stove so far, have Wei (far) steel, Lianyuan Iron and Steel, Han Steel, Nanchang Steel 300m ~ 3 blast furnace with a ball-type stove. According to statistics, the wind temperature at 1050 ~ 1150 ℃, up to 1200 ℃ (short);
