摘要 在实验室研究了温度、粒度对烧结矿、球团矿和焦炭吸附铅蒸气的影响，并对吸附铅蒸气后炉料的冶金性能进行了研究。结果表明：温度为1 000 ℃时，炉料的铅吸附率出现最大值，随粒度增大，吸附率降低；随着铅吸附量的增加，烧结矿、球团矿的RDI增加，焦炭的反应性增强，反应后强度降低。控制炉料粒度是提高高炉排铅率的有效措施。

| Abstract Lead vapor adsorption behavior in blast furnace burden with different temperature and size was studied in laboratory, and metallurgical properties of blast furnace burden containing lead were measured. The results showed as follows: the adsorptive rate of lead in the burden reached maximum at about 1 000 ℃ and it decreased with size increase; when the adsorptive rate of lead increased, RDI of sinter and pellet increased and CRI of coke increased, CSR of coke decreased. Controlling the size of blast furnace burden is the best way to increase the lead removal rate of blast furnace burden. |
