包钢1^(#)高炉安全环保空料线停炉实践

Practices of Blowing out by Lowering Charge Level for Safety and Environmental Protection of 1#Blast Furnace of Baotou Steel

本次停炉采用空料线停炉操作法,通过活跃炉缸、计算分析装轻负荷料、前期采用大风量尽可能的快速燃烧焦炭、改进雾化装置减少炉顶打水量、细化炉前出铁、合理控制压量关系、缩短煤气放散时间、高效组织、安全放残铁工作、协调各系统等,降料线过程总体比较顺利,达到了全程无爆震、安全、环保、快速停炉。

The process of blowing out by lowering the charge level is smooth.Moreover,the whole process without detonation,rapid blowing out with safety and environmental protection are realized through activating the furnace hearth,calculating and analyzing loading of light load materials,adopting high blowing rate in early stage to make coke burnt as quickly as possible,improving atomization device to reduce the amount of water injected into furnace top,refining tapping in stokehole,reasonably controlling the relationship between air pressure and blowing rate,shortening the time of gas release,efficiently organizing,safely placing residual iron and coordinating various systems.
