涟钢高褐铁矿配比烧结生产实践

PRODUCTION PRACTICE OF SINTERING WITH HIGH PROPORTION OF LIMONITE AT LIANGANG

如何进一步提高褐铁矿的烧结配比,成为各钢厂降低配矿成本关注点。根据褐铁矿烧结特性及高褐铁矿配比烧结研究现状,涟钢在实验室研究基础上,将360m2烧结机褐铁矿比例提高至40%以上。实践证明,烧结矿质量指标能保持原有水平,高炉可以长周期稳定顺行,并取得较好的经济效益。

How to further improve the sintering proportion of limonite has become the focus of steel mills to reduce the cost of ore matching.According to the sintering characteristics of limonite and the research status of sintering with high proportion of limonite,Liangang has increased the proportion of limonite to more than 40%in 360 m2 sintering machine based on the laboratory research.The practice has proved that the quality index of sinter can keep the original level,the blast furnace can run smoothly for a long period and get good economic benefit.
