提高炉顶煤气CO_2%,改善煤气能量利用,有利于节焦增产,这对生铁高炉已属定论,但就锰铁高炉而言,认识尚不统一,甚至存在着“因为锰在高炉内基本上是100%直接还原,故锰铁高炉煤气能量利用无关紧要”的错误观点.本文试对我厂锰铁高炉生产数据进行回归分析,找出炉顶煤气CO_2%和入炉焦比之间的定量关系并进行计算验证,以利澄清认识.促进锰铁高炉节焦增产.
Improve the top gas CO_2%, improve gas energy utilization, is conducive to coke production, which is a conclusion of pig iron blast furnace, but the ferromanganese blast furnace, the understanding is not uniform, and even exists “because the manganese in the blast furnace basically Is 100% direct reduction, so the energy utilization of ferromanganese blast furnace gas is irrelevant. ”This paper tests the production of ferromanganese blast furnace production data regression analysis to find the top gas CO_2% and the ratio between the furnace into the quantitative relationship And to verify the calculation to facilitate the clarification of understanding. Promote the production of ferromanganese blast furnace Festival.
