2#高炉项修综合技术开炉快速达产达效实践

Practice of Achieving Production Targets with Advanced Techniques during Item Repair for #2 BF

阐述炼铁厂2#高炉项修开炉综合应用全风口开炉、铁口专用导风管、带风投料和预热送风等4项先进技术,实现了开炉点火后19小时全风、22小时喷煤,24小时达产达效。

Four advanced techniques were adopted during item repair for #2 BF,such as blow-in with opening all tuyeres,special duct for taphole,charging with blast and preheating hot blast,which has realized full blast within 19 hours,coal injection within 22 hours and achieved production targets within 24 hours after blast furnace ignition.
