对4种不同成分的生石灰进行了活性度检测,并将这4种生石灰分别添加进烧结混合料中进行烧结杯试验,研究了其对烧结矿质量的影响。试验结果表明,石灰的活性度越高,其成分有效CaO的含量越高。在烧结生产中配加高活性度生石灰,有利于提高烧结成品率和烧结矿强度,加快垂直烧结速度,提高烧结生产效率,并使烧结矿粒级分布趋于合理。
The activity of four kinds of quicklime was tested, and the four kinds of quicklime were respectively added into the sintering mixture to carry out the sintering cup experiment. The influence on the quality of sinter was studied. The experimental results show that the higher the activity of lime, the higher the content of CaO. In the sintering production with high activity of quick lime, is conducive to improving the sintering yield and sinter strength, speed up the vertical sintering speed, improve the sintering production efficiency, and make the sinter particle size distribution tends to be reasonable.
