鞍钢烧结总厂烧结矿质量的主要问题之一是氧化亚铁高,一般为18％左右,还原性能较差。采用热风烧结是降低其含量的有效措施。为了提高烧结矿质量,降低氧化亚铁含量,该厂经过几个月的准备,自己设计,自己施工,制成了“管式热风烧结”的试验设备,于十一月初在第二烧结车间4号烧结机正式进行工业试验,初步获得了良好效果。 One of the major problems of sinter quality at Ansteel Sinter Plant is that ferrous oxide is high, generally about 18%, and the reduction performance is poor. The use of hot air sintering is an effective measure to reduce its content. In order to improve the quality of sinter and reduce the content of ferrous oxide, after several months of preparation, the factory designed and built it by itself and made the test equipment of “tube-type hot air sintering”. In early November, No. sintering machine formally carried out industrial tests, initially obtained good results.
