摘　　要：武钢炼铁技术进步主要体现在以下方面:大型高炉高效冶炼技术,如8号高炉在入炉品位低、渣比高的条件下,利用系数2.5,煤气利用率49.53%,燃料比502.7kg/t;延长高炉寿命技术,如8号高炉至今已生产6年半尚无一根冷却壁水管损坏;创新炉身结厚处理技术,成功率在80%以上;探索高锌负荷冶炼规律,保证高炉的稳定顺行;高炉停炉回收煤气,节能环保;焦丁、除尘煤粉和干熄焦粉的回收再利用,降低制造成本;延长炉顶设备使用寿命,如溜槽使用寿命从3—6个月延长到12—24个月。WISCO achieves ironmaking technological progresses thanks to following technologies adopted;(a) large sized blast furnace high efficient smelting process,which features high production(2.5) and high gas utilization(49.53%),and low fuel ratio(502.7 kg/t) under the preconditions of low grade burden and high slag ratio(e.g.in WISCO's No.8 BF);(b) long campaign technology of blast furnace,which allows zero cooling stave water pipe damage in the past 6.5 years operation of No.8 BF;(c) stack wall accretion treatment technology with success rate of over 80%;(d) exploration of BF melting mechanism under high zinc load for ensuring stable and smooth BF operation;(e) recycling of BFG,which results in energy saving and emission reduction;(f) recycling of coke nut,coal dust obtained from dust collect and dry quenched coke breeze for lowering production cost;(g) long service life technology of BF top equipment,which permits,for instance,12 to24 months service life of chute from the original 3 to 6 months.
