在烟气温度一定时，随着氧含量降低料层最高温度呈线性下降。在氧含量一定时，通过提高烟气温度可弥补氧含量的不足，达到提高料层最高温度的效果。从料层最高温度值所在位置变化来看，烟气温度提高以及氧含量降低均使烧结料层的最高温度点上移。

When the flue gas temperature is constant, the maximum temperature of the material layer decreases linearly with the decrease of oxygen content. When oxygen content is constant, the lack of oxygen content can be made up by raising flue gas temperature, so as to increase the maximum temperature of the material layer. From the position change of the maximum temperature value of the sintering layer, the maximum temperature point of the sintering layer moves up with the increase of flue gas temperature and the decrease of oxygen content.
