1、兰炭用作燃料对烧结性能影响的试验研究何木光細攀枝花钢钒有限公司炼铁厂摘要：采用兰炭用作烧结燃料进行Y实验室试验，探索兰炭的燃烧性能与对产质量指标的影响，并进行相关对比试验及技术经济评价。试验结果表明使用兰炭的烧结利用系数达到1.549t/(m2•h),高出焦粉0.177t/(m2•h)，高出煤粉0.146t/(m2•h):转鼓指数达62%,比使用焦粉高2.93%,比使用煤粉高8.8%;固体燃耗52.22kg八，比焦粉低2.24kg八，比煤粉低8.32kg八。综合评价烧结性能兰炭是三种燃料中最高的。兰炭灰分低，相同配

2、矿条件下可提高烧结矿品位0.3%°.5%。使用兰炭烧结矿矿物组成与结构更加均匀，铁酸盐含量高，玻璃质含量少，低温还原粉化率低，中温还原度高。技术与经济评价表明，兰炭用作烧结燃料，其综合技术效果最高，而烧结矿成木最低，为未来可选的烧结优质燃料之一。关键词：兰炭;燃料性能;烧结试验;性能指标;矿物组成;冶金性能;综合评价;作者简介：蒋大军(1965-),高级工程师;617024四川省攀枝花市。收稿日期：2017-05-24Experimentalresearchonsinteringperformanceinfluen
