介绍了2008年年底以来新钢烧结厂在降低烧结矿碱度方面所做的工作,包括:不同碱度水平的试验室研究;在试验研究的基础上,实施稳定原料质量,提高生石灰配比,优化配矿等措施。通过开展这些工作,保证了烧结矿碱度降至1.8以下时,其产质量指标仍能较好地满足高炉生产要求。 This paper introduces the work done by Xinxin Sintering Plant since the end of 2008 to reduce the alkalinity of sinter, including: laboratory research on different alkalinity levels; on the basis of experimental studies, implementing stable raw material quality, increasing the proportion of quicklime, Optimization with mining and other measures. Through these efforts, it is guaranteed that when the basicity of sinter drops below 1.8, its production and quality indexes can still meet the requirements of blast furnace production well.
