烧结矿碱度下调的试验与生产

THE EXPERIMENTS AND OPERATIONAL PRACTICES ON THE DECREASING SINTER BASICITY PRODUCTION

试验与生产表明 ,在太钢现有原料条件下 ,将烧结矿碱度从 1.75下调至 1.5,可提高烧结矿品位 ,增加烧结矿入炉配比 ,改善烧结矿的软熔性能 ,形成较合理的炉料结构 ,高炉技术指标改善较明显 ,同时烧结机的生产能力也得到充分发挥 ,总的经济效益可观。

The results of experiments and operational practices show:At present ,according to the concentrates condition in Taigang, the change of sinter basicity from 1.75 to 1.5 can raises ferrous content of sinter,increases the sinter charging ratio of BF and improves sinter softening properties,the technical index of BF has been improved to a great extend.At the same time,the sinter plant production bility can exerted plenty.The economical benifit is obviously.
