摘要: 系统分析了冶炼含钒铁水特殊工艺条件下影响转炉煤气回收的诸多因素。通过工业试验优化了相关工序环节的操作和控制水平,如:调整活动烟罩高度,炉口微压控制,优化炼钢吹炼过程的加料制度,确保转炉煤气的平稳回收,优化造渣制度及氧枪操作方式,修订煤气回收限值等,提高了炼钢工序煤气回收水平。在半钢炼钢条件下转炉煤气回收量达119.87 m³/t,煤气热值达5 578.655 kJ/m³。

Abstract: Systematic analysis of various influence factors on converter gas recovery under the special processes of smelting vanadium-containing molten iron was carried out in this paper. Through industrial experiments,the condition of operation and control level of the relevant processes were optimized,including adjustment for the height of moving petticoat pipe,micro pressure control of the converter mouth,improvement of the feeding for blowing process in steelmaking,optimization of slagging and oxygen lance operation,and modification of limit value for gas recovery. The gas recovery in steelmaking process was efficiently improved,with 119.87m³/ t of recovery ratio and 5578.655 kJ/m³ of heat value under semisteel steelmaking.
