1.概况自六十年代末至八十年代初,对12座高炉做了解剖研究。这不仅使人们对炉内条件和炉料行为有了更多了解,而且成为提出有关验证高炉内部结构和新操作概念的起点。在更早一些时候,钢铁工业内、外部条件的变化使炼铁工艺面临新挑战,也促进了炼铁理论和研究的发展。例如1974年曾出现优质焦煤大幅度短缺引起焦炭质量暂时下降,从而导致了许多高炉操作失常。为此,深切地感到需要开发将燃料煤用于炼焦的方法和研究建立评价焦炭在高炉内质量劣化的方法等。另一方面,竭力降低燃料比使得最低燃料比的纪录不断刷新,以及通过提高入炉料质量和适当控制炉料分布来改善煤气利用,这些都受到人们的特殊赞赏。因此在高炉停 1. Overview From the late 1960s to the early 1980s, 12 blast furnaces were dissected. This not only gives people a better idea of ​​the conditions in the furnace and the behavior of the charge, but also serves as a starting point for verifying the internal structure of the blast furnace and the concept of a new operation. Earlier, changes in external and internal conditions within the steel industry placed the ironmaking process under new challenges and promoted the development of ironmaking theory and research. For example, there was a temporary drop in the quality of coke that led to a substantial shortage of high-quality coking coal in 1974, resulting in many blast furnace operations. For this reason, it is deeply felt that there is a need to develop a method of using fuel coal for coking and to establish a method of evaluating the quality deterioration of coke in a blast furnace. On the other hand, efforts to reduce the fuel ratio so that the lowest fuel ratio record constantly refreshed, and by improving the quality of charge into the charge and control the distribution of the charge to improve gas utilization, which are particularly appreciated. So stop in the blast furnace
