鞍钢3200 m^3高炉大修技术应用与开炉达产实践

Technology Application of Heavy Maintenance for 3200 m^3 BF in Ansteel and Practice of Achieving Target Output after Blowing-on

对鞍钢新1号高炉大修过程中炉底、炉缸砖衬,冷却壁、冷却板及破损炉壳更换,以及新增干法除尘等工艺装备所采用的相关技术进行了介绍,同时对高炉大修后的开炉工作,如炉体烘炉,试漏、试压,装填开炉料,开炉进程以及过程中执行的相关制度进行了说明。此次高炉大修及开炉各项工作都按计划如期完成,顺利达产,取得较好效果。

During the heavy maintenance of the new No.1 BF of Ansteel,these operations such as replacing the furnace bases,hearth brickings,cooling staves,cooling plates and damaged furnace shells and correlation technologies applied by the new additional dry dedusting equipment were introduced,and also the blowing-on operations after finishing the heavy maintenance of the new No.1 BF such as pre-heating the furnace body for blowing-on,leak test,pressure test,charging furnace burden and related schedules for the blowing-on process and work-in-progress control procedures of the process were explained.For the heavy maintenance and blowing-on of the new No.1 BF all kinds of operations were done on time and the target output was achieved smoothly and good results were also achieved.
