摘要
在太钢目前的烧结原料条件下 ,进行了不同碱度烧结的实验室试验。结果表明 :烧结矿碱度由 1.8～ 1.9降为 1.7左右时 ,其转鼓强度 (ISO转鼓 )下降约 3个百分点 ;碱度由1.7降至 1.5时 ,转鼓强度变化不大 ,但在此碱度范围内 ,烧结矿的自然粉化较严重。烧结矿的还原度随碱度的升高而升高 ,低温还原粉化率则随碱度升高相应得到改善。但为了充分发挥太钢的烧结生产能力 ,提高烧结矿入炉比 ,生产碱度为 1.5的烧结矿是可行的 ,而且烧结矿质量能满足炼铁生产要求。
According to the sinter mix materials used in Taiyuan I&S Co.,laboratary test were conducted.The results had shown that sinter quality get worser with the basicity of sinter becoming low. Especialy tumble index decreased 3 percentage points with the basicity of sinter decreasing from 1.9 ~ 1.8 to 1.7.But in order to give a full play to the sintering capacity and to increase the sinter ratio of BF burden , the sinter can be produced successfully with basicity as 1. 5 and the quality of sinter can completely met the needs of ironmaking production.
