1号高炉于1987年12月10日进行了第二代第二次中修。此次中修停炉操作,吸取了国内的先进经验,改进了传统的操作方法,大大减少了加净焦量;停炉过程中,维持风量大、风温高,炉顶打水按计量控制,炉顶温度稳定,停炉过程中减少了再次低压安装炉顶打水管的程序。停炉过程由传统方法的平均22小时35分缩短到12小时58分,达到了安全、顺利停炉的目的。一、停炉前的工作 1.停炉前的炉况调整停炉前、要求炉况顺行,炉温充足,碱
No. 1 blast furnace on December 10, 1987 for the second generation of the second repair. The repair operation in the furnace, drawing on the advanced experience of the country, improved the traditional method of operation, greatly reducing the amount of plus net focus; shutdown process, to maintain large air volume, high temperature, , The temperature of the top of the furnace is stable, and the procedures of installing the top of the furnace at the low pressure during the shutdown process are reduced. The shutdown process was shortened from the average of 22 hours and 35 minutes to 12 hours and 58 minutes of the traditional method, achieving a safe and smooth shutdown. First, before the shutdown of the furnace 1. Before stopping the furnace temperature adjustment Shut down the furnace, the furnace conditions required to go straight, sufficient temperature, alkali
