武钢2~#高炉(1551米~3)大修设计中首次采用了双钟双阀和活动布料环炉顶结构,已于1982年6月16月投产.炉顶改造主要特点是:双钟双阀武钢2~#高炉炉顶原为双钟马基式布料器,虽然炉顶压力能达1.3公斤/厘米~2左右,但大钟寿命较短,对进一步挖掘风机潜力,提高炉顶压力受到了限制.因此,决定在不大动炉顶设备及结构的前提下,将斜桥上部抬高400毫米,新增加两个盘式密封阀,将受料漏斗由一个改成两个,布料器上部用半球壳体作为小钟气封罩.小钟与小钟斗间采用了硅橡胶软密封,以提高
Wuhan WISCO 2 ~ # Blast Furnace (1551 m ~ 3) overhaul design for the first time using a double bell dual-loop and active fabric ring roof structure, has been put into operation in June 1982. Roof key features are: double bell double valve WISCO 2 ~ # blast furnace roof was originally a two-bell horse-based distributor, although the roof pressure can reach 1.3 kg / cm ~ 2 or so, but the short life of the clock, to further tap the potential of the fan to improve the roof pressure by Therefore, the decision not to move the top equipment and structure of the premise, the upper part of the inclined bridge elevation 400 mm, add two new disc seal valve, the funnel from one to two, the upper part of the distributor Use the hemispherical shell as a bell seal. The small bell and the bell have a silicone rubber soft seal to enhance
