摘　　要：气氛烧端炉中的气体流动特性对烧结效果非常重要。研究指出,适中的气流速度有助于提高热传输效率和加热速度,同时保持炉内压力的稳定性与气氛的纯净,减少原料的损耗并提升燃料的使用效率。然而,气流速度若超出适宜范围,则可能导致炉内压力变化不稳定、气氛纯净度下降、原料消耗量增加以及燃料效率降低等问题。通过改进燃烧器的位置设计、调整风门的开启程度和引入先进的控制方法,可以有效调控气流速度,进一步提升烧结过程的质量和效率。此研究为气氛烧端炉的设计与操作提供了有益的指导。The gas flow characteristics in the atmosphere burning furnace are crucial for the sintering effect.Research has shown that moderate airflow velocity helps to improve heat transfer efficiency and heating speed,while maintaining stable furnace pressure and pure atmosphere,reducing raw material loss,and enhancing fuel efficiency.However,if the airflow velocity exceeds the appropriate range,it may lead to unstable pressure changes in the furnace,decreased atmosphere purity,increased raw material consumption,and decreased fuel efficiency.By improving the position design of the burner,adjusting the opening degree of the air damper,and introducing advanced control methods,the airflow velocity can be effectively regulated,further improving the quality and efficiency of the sintering process.This study provides useful guidance for the design and operation of atmosphere fired end furnaces.
