通过在铁精矿粉中配加镁质粘结剂进行了生产镁质球团矿的试验研究。研究结果表明,与酸性球团矿相比,配加镁质粘结剂生产MgO球团矿时所需要的预热温度和焙烧温度均较高,且焙烧时间也较长。但对铁精矿和镁质粘结剂混匀进行润磨预处理能改善MgO球团矿预热焙烧性能。混合料经润磨预处理后,球团矿预热温度能降低80℃,焙烧温度至少能降低30℃,焙烧时间至少能缩短4min。 The production of magnesia pellets was studied by adding magnesia binder to the iron concentrate powder. The results show that, compared with acidic pellets, MgO pellets with MgO binder require higher preheating temperature and calcining temperature and longer calcining time. However, pretreatment of the mixture of iron ore concentrate and magnesia binder can improve the preheating roasting performance of MgO pellets. After the pretreatment of the mixture by moistening, the preheating temperature of the pellet can be reduced by 80 ° C, the baking temperature can be reduced by at least 30 ° C, and the baking time can be shortened by at least 4 minutes.
