摘要
对首钢京唐1号高炉降低燃料比的生产实践进行了总结。通过采取一低(低渣比)、四高(高风温、高富氧、高顶压、高煤气利用率)、四适宜(适宜的煤比、适宜的鼓风湿度、适宜的冶炼强度、适宜的炉体热负荷)等措施,1号高炉燃料比下降到480kg/t左右,焦比下降到270kg/t左右,实现了低燃料比生产。
the paper summarizes the production practice of No. 1 BF at low fuel ratio in Shougang Jing - Tang United Iron ＆ Steel Co. ,Ltd. In this furnace a series of advanced technologies are taken, such as low slag ratio, high blast temperature, oxygen enrichment, top pressure and gas utilization efficiency, appropriate coal ratio, blast temperature, smelt intensity and furnace body heat load, which result in decrease of fuel ratio down to 480 kg/t approximately and decrease of coke ratio down to about 270 kg/t, and achieve BF production at low fuel ratio.
