一、前言活性石灰是石灰石经煅烧而成。一般含CaO85％以上,活性度为300毫升以上。活性石灰具有易裂缝、质脆易破碎、吸水性强、易自然粉化、活性度高、加水消化时能放出大量热产生较大的比表面积等特征。在细磨精矿的烧结过程中,配加适当的活性石灰,可以大幅度地强化烧结过程,提高烧结矿的产、质量。这一结论早已被国内外的生产实践所证实。从国内外资料获悉,添加活性石灰烧结,可大幅度提高产量(20％以上)。1984年7月,烧结厂研究室在武钢原料条件下,进行了添加活性石灰的试验,配加3～5％粒度0～3毫米的活性石灰烧结时,在保证 First, the foreword Active limestone is calcined from limestone. General CaO85%, activity of 300 ml or more. Active lime has the characteristics of easy cracking, brittleness and fragility, strong water absorption, easy natural pulverization, high activity, large amount of heat generated when water is digested, and large specific surface area. Fine grinding concentrate in the sintering process, with appropriate active lime, can greatly enhance the sintering process and improve the sinter production and quality. This conclusion has long been confirmed by domestic and foreign production practices. It is learned from domestic and foreign sources that the addition of active lime sinter can greatly increase the output (over 20%). July 1984, Sinter plant in WISCO raw materials under the conditions of the trial, adding activated lime, with 3 ~ 5% granularity 0 ~ 3 mm active lime sintering, the guarantee
