为了适应铁矿石资源供给情况的变化,同时也为了降低烧结矿Al2O3含量,改善高炉渣系,降低生产成本,需要探索扬迪粉在烧结中的大比例配用问题。经过扬迪粉配比由12%逐步提高到30%的生产实践发现,通过合理搭配提高扬迪粉比例,不会影响烧结生产质量,扬迪粉配比30%时,烧结矿质量较稳定,生产成本有所下降。
In order to adapt to the change of iron ore resource supply, and also to reduce the content of Al2O3 in sinter, improve the blast furnace slag system and reduce the production cost, it is necessary to explore the large proportion of the use of Jandi powder in sintering. After the ratio of JYD gradually increased from 12% to 30%, it was found that by improving the proportion of JYD properly, it will not affect the quality of sintering. When the ratio of JYD is 30%, the quality of sinter is stable, Production costs have declined.
