摘　　要：连续热镀锌机组NOF燃烧系统作为无氧加热段,采用明火烧嘴直接加热带钢,因为其属于无氧化氛围控制,所以热效率较高。但在实际生产中发现NOF排烟出现冒黑烟现象,无氧化氛围被破坏,无法满足生产工艺要求。针对以上问题,对NOF无氧化加热段故障处理进行实践分析,最终结合流量计算找出原因,并进行了相应处理,降低了镀锌机组的故障率,提高了机组的可靠性及工艺产品的质量。As an anaerobic heating section,the NOF combustion system of the continuous hot-dip galvanizing unit uses an open flame burner to directly heat the strip steel.Due to its non oxidizing atmosphere control,it has a high thermal efficiency.However,in actual production,it was found that NOF smoke emitted black smoke,and the non oxidizing atmosphere was damaged,which could not meet the production process requirements.In response to the above issues,an analysis and practice were conducted on the fault handling of the NOF non oxidation heating section.Finally,the cause was identified through flow calculation and corresponding measures were taken to reduce the failure rate of the galvanized rolling unit,improve the reliability of the unit,and improve the quality of process products.
