西钢铁前系统有选矿工序、烧结工序、球团工序、焦化工序和炼铁工序,2002年上半年铁产量110068t、烧结产量185470t、焦炭产量52791t、球团产量50731t。2001年1号高炉和烧结机进行了大修扩容改造,分别改造为130m~3和29m~2,2002年将2号高炉扩容改造为130m~3,并正在筹建50000m~3煤气贮柜,现高炉进行富氧喷煤,富氧率为2.45%,喷煤比为120kg/t,从纵横两方面对西钢铁前系统进行分析。
In the first half of 2002, the iron output was 110068t, the sintering output was 185470t, the coke output was 52791t, and the pellet output was 50731t. 2001 No. 1 blast furnace and sintering machine was overhauled expansion transformation, respectively, transformed into 130m ~ 3 and 29m ~ 2, in 2002 the No. 2 blast furnace expansion to 130m ~ 3, and is preparing to build 50000m ~ 3 gas storage tank is blast furnace Oxygen-rich coal is injected into the coal to make the oxygen enrichment rate 2.45% and the coal injection ratio 120kg / t. The pre-West steel system is analyzed in both vertical and horizontal directions.
