1 前言按照公司要求,一铁厂2000年烧结生产使用地方矿粉,由于地方矿粉厂家多、成分不稳,加之品位低,SiO_2含量高,势必造成烧结矿碱度波动,烧结消耗熔剂石灰石和高炉消耗矽石增加,这直接影响高炉正常生产。为了解地方矿粉烧结性能和减少其对高炉生产影 1 Introduction According to the company’s requirements, a iron mill in 2000 sintering production of local use of local ore powder, as many local producers of slag, composition instability, combined with low grade, high content of SiO2, is bound to cause sinter alkalinity fluctuations, sinter consumption of flux limestone and Blast furnace consumption of silica increased, which directly affects the normal production of the blast furnace. In order to understand the local ore sintering performance and reduce its impact on blast furnace shadow
