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 k J/m3。 Systematic analysis of the smelting vanadium-containing molten iron under the special conditions affect the converter gas recovery many factors. Optimized the operation and control level of relevant process steps through industrial experiments, such as adjusting the height of hood, micro-pressure control of furnace mouth, optimizing feeding system in steel-making process, ensuring smooth recovery of converter gas, optimizing slagging system and Oxygen lance mode of operation, revised gas recovery limits, etc., to raise the gas recovery process steelmaking level. In semi-steelmaking, converter gas recovery reached 119.87 m3 / t and gas calorific value reached 5 578.655 kJ / m3.
