底焦的燃烧过程是决定着冲天炉工作过程的主要因素。其它条件相同时,焦炭废气温度愈高,炉料和气体间进行的热交换愈充分,铁水和渣也愈炽热,对铁渣间反应更完全进行的条件也愈好,冲天炉出铁温度也愈高。所以最大限度地提高废气温度来影响燃烧过程,是保证改善为提高铁水质量所需 Bottom coke combustion process is the main factor determining the work process of the cupola. Other conditions are the same, the higher the coke exhaust gas temperature, the more heat exchange between the charge and gas, the hotter the molten iron and slag, the more complete the reaction conditions between the iron slag is also better, the cupola temperature out high. Therefore, to maximize the exhaust gas temperature to affect the combustion process is to ensure that improvements to improve the quality of hot metal required
