在掌握金属化球团及其他含铁原料特性的基础上，采用熔滴试验方法，考察不同比例金属化球团对高炉冶炼过程的影响。试验结果表明：金属化球团具有含铁品位高、金属化率高、还原性能好、无低温还原粉化、软熔滴落性优良等特点，在高炉中配加金属化球团其综合炉料的软熔滴落性能变好，但考虑到配加金属化球团后减少焦比对高炉的影响，其配加比例在20％（质量分数）左右比较适宜。
Based on the properties of metalized pellets and other iron bearing materials ,the influence of different rati‐os of metalized pellets on blast furnace smelting process was investigated by means of melting‐dropping experiments . The results showed that metalized pellets had the characteristics of high iron grade ,high metallization rate ,high re‐ducibility ,high RDI+3 .15 and excellent softening dropping property .When metalized pellets were added in blast fur‐nace burden ,the softening dropping property got better .And the appropriate ratio of metalized pellets was 20% , considering that adding metalized pellets could reduce the influence of coke rate on blast furnace .
