太钢4350m3高炉2010年2月28日因为炉顶中心喉管膨胀节跑煤气造成非计划休风18 h 50min。此次送风恢复过程中视炉热水平,轻负荷料下达位置及炉况接受情况分3个阶段进行风量和富氧量的恢复。同时,通过适量多补充喷煤量,用足风温和安排合理的炉前作业等,实现了炉况的成功快速恢复。
TISCO 4350m3 blast furnace February 28, 2010 Unconventional break due to expansion of gas in the center of the top center of the furnace 18h 50min. The recovery of the blast furnace heat level, light load material release position and furnace conditions accepted three stages of air volume and oxygen recovery. At the same time, the successful and rapid recovery of the furnace condition has been achieved through a modest amount of additional coal injection, a modest footwork arrangement with furnace footwork, and the like.
