| 摘 要： | 以常用的炼铁原料为基础，系统研究了配加不同比例的热压含碳球团对高炉炉料的软熔滴落性能的影响，并进行了理论分析。研究表明，配加热压含碳球团对高炉综合炉料的软化区间、熔化区间、滴落率和透气性等软熔滴落性能参数有显著的影响。随着热压含碳球团配比的增加，软化区间t40-t4逐渐变宽；熔化区间tD-tS逐渐变窄，熔化开始温度tS逐渐升高，滴落温度tD逐渐降低；滴落率先增加后降低，当配比为40%时，滴落率最高，为6710%；最高压差先下降后升高，但在配加热压含碳球团条件下，炉料的最高压差都有所降低。从综合炉料的软熔滴落性能综合考虑，高炉炉料配加热压含碳球团的适宜配比应为40%~50%。

| Abstract: | Effects of carbon composite iron ore hot briquette(CCB) with different charging proportions on the softening-dripping behavior of blast furnace burdens were investigated systemically and theoretically,based on the common iron-making materials.The results show that charging CCB affects greatly on the softening-dripping parameters of blast furnace burdens,such as softening range,melting range(or cohesive zone),dripping ratio,gas permeability etc.With the increasing CCB charging ratio,the softening range t40-t... |
