我国的无钟炉顶装置自从1979年率先在首钢新2号高炉投产以来,继而在国内得到了很大的发展,出现了多种形式的设备结构。但是,截至1989年上半年为止,其实际的布料功能却变化不大。现将目前国内无钟炉顶的现状及形成该现状的原因作一简要叙述及肤浅的分析。一、对无钟炉顶布料功能含义的理解从我们自行设计的无钟炉顶布料功能来看,设计说明中提到具有四种布料功能,即①定点布料;②单环布料;③多环布料;④螺旋布料。可是到高炉投产后,高炉工长却指出,实际生产中只能实现前二种布料功能,即定点布料和单环布料。那么实际与设 Since the first bell-less top installation in our country was put into operation in Shougang’s new No. 2 blast furnace in 1979, it has been greatly developed domestically and many kinds of equipment structures have emerged. However, as of the first half of 1989, the actual fabric function has not changed much. Now the current status of the domestic bell-less roof and the reasons for the formation of a brief description and superficial analysis. First, the understanding of the meaning of the bell-less roof fabric function From our own design bell-less roof fabric function point of view, the design description mentioned with four kinds of fabric features, namely ① fixed-point fabric; ② single-ring fabric; ③ multi-ring Cloth; ④ spiral cloth. However, after the blast furnace was put into operation, the blast furnace supervisor pointed out that only the first two kinds of cloth functions can be realized in the actual production, namely the fixed-point cloth and the single-loop cloth. So practical and set
