摘要
宝钢2号高炉在2012年和2014年进行过两次降料线操作,目的是对炉身下部耐材进行修补,两次作业的料线深度分别达21.5和20.5 m。分析对比两次降料线操作,除了大风量操作、雾化打水、高压操作、通氮气等以往的成功经验,2014年还在延长大风量时间、打水量控制、炉顶煤气监测等方面做了改进,使得2014年的降料线操作有了更大的进步。
Two operations of dropping stockline both in the year 2012 and 2014 in No. 2 blast furnace of Baosteel were conducted. The purpose of these two operation was to repair the lower part refractories of the blast furnace. The depth of these two operation ＇s stockline were 21. 5 m and20. 5 m respectively. The mature experiences gained in these two operations were summarized. In addition to the successful practices of high blast volume,atomize water,high pressure control,blow nitrogen gas,etc.,some improvements such as extension of time for high blast,water adjustment,top gas detector were applied in 2014. All these approach made the dropping stockline success in 2014.
