八钢欧冶炉双炉降料面停炉实践

Operation Practice on Shutdown of Dropping Charge Level in Two Furnaces of OY Furnace of Bayi Steel

文章对欧冶炉停炉操作实践进行了分析,欧冶炉双炉均采用炉顶打水喷雾装置进行打水降料面方法。介绍了停炉全过程,主要包括停炉前的准备工作及其炉况调整,采用提高顶煤气量降竖炉料面、炉顶打水控制炉顶温度及气化炉加大氮气量稀释炉内O_(2)含量等安全措施,为欧冶炉双炉降料线停炉提供了安全工艺技术支持。

The article analyzes the operation practice of the OY furnace shutdown,and adopts the method of water spraying and spraying at the top of the furnace to make the water lowering and charging face method. This paper introduces the whole process of boiler shutdown,mainly including the preparation before boiler shutdown and the adjustment of furnace condition,adopting safety measures such as increasing the top gas volume,reducing the charge level of shaft furnace,drawing water from furnace top,controlling the furnace top temperature,increasing the nitrogen volume of gasifier and diluting the O;content in furnace,which provides safety process and technical support for the shutdown of two furnaces material reduction line of OY furnace.
