高炉操作者的任务之一就是通过各种调节手段来获得规则合理的煤气曲线,使煤气流的化学能和热能得到充分利用。我厂的三座225m~3锰铁高炉近十年来煤气曲线一直紊乱,没有规则。为了弄清锰铁高炉煤气曲线紊乱的原因,作者将锰铁高炉投产以来二十余年的煤气曲线进行统计分析,并特别 One of the tasks of the blast furnace operator is to obtain a well-regulated gas curve through various means of adjustment so as to make full use of the chemical energy and thermal energy of the coal gas stream. I plant three 225m ~ 3 ferromanganese blast furnace gas curve over the past decade has been disorderly, there is no rule. In order to understand the cause of the disorder of the gas curve of the ferromanganese blast furnace, the author carried out the statistical analysis of the gas curve of more than 20 years since the commissioning of the ferromanganese blast furnace, and in particular
