The effective volume of 7# blast furnace of Baotou Steel is 4 150 m3. On October 23rd, 2022, it was blown down for gunning of lining and remolding inner profile. In the blowing down, the method of dropping stockline by spraying water was adopted and the stockline was dropped to a position below center line of tuyere. The methods of reducing the basicity of furnace slag ahead of time and increasing furnace temperature were taken to increase wall temperature, the match of air and oxygen quantities and assessment method of depth of stockline different from the past as well as the method of spraying water, that is, monitoring the mean value and difference value trend of four points of top temperature to control the water quantity were adopted. After taking the above measures, stockline could be dropped safely and rapidly.

包钢7#高炉有效容积为4 150 m3,2022年10月23日停炉对内衬进行了喷补,重塑炉型。停炉采用空料线打水降料线的方式,料线降到了风口中心线以下位置。本次停炉采取了提前降炉渣碱度、提高炉温的方式来提高壁体温度,采用不同以往的风氧量匹配、料线深度评估方式以及采用监控炉顶四点顶温均值和差值趋势来控制水量的打水方式。采取上述措施后,实现了安全、快速降料线。
