通过测量铁矿 煤球团在空气中还原时料层温度上升规律和气体成分变化情况 ,得出了球团被加热到挥发分开始激烈析出温度时 ,挥发分开始燃烧 ,放出的热是将球团加热到碳的直接还原开始激烈进行温度时 ,碳的还原产生的CO气体开始燃烧 ,提供球团还原耗热 .
By measuring the rising law of the temperature of the material layer and the change of the gas composition when the iron ore pellets are reduced in the air, it is concluded that when the pellets are heated to the temperature where the volatiles begin to precipitate intensely, the volatiles begin to burn and the heat released is the pellets Heating to direct reduction of carbon begins intense heating of the carbon monoxide produced by the reduction of CO gas combustion, to provide pellet reduction heat.
