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。
The technological progress of WISCO ironmaking is mainly reflected in the following aspects: Efficient smelting technology for large-scale blast furnaces. For example, when No.8 blast furnace is in a low-grade furnace with a high slag ratio, the utilization factor of 2.5, gas utilization rate of 49.53% and fuel ratio of 502.7kg / t ; To extend the life of the blast furnace technology, such as the No.8 blast furnace has been produced for 6 years and a half did not have a cooling pipe damage; innovative furnace body knot thickening technology, the success rate of 80% or more; explore the high zinc load smelting law to ensure that the blast furnace Stable and smooth; blast furnace shut down to recover gas, energy saving and environmental protection; Jiao Ding, coal dust and CDQ recovery and reuse, reduce manufacturing costs; Extend to 12-24 months.
