使用１４００／８５０Ｗ的微波炉，在实验室研究了微波加热磁铁矿球团时球团矿的温度变化规律、干燥特点、生球强度和焙烧后球团的岩相特征，并对固结机理进行了探讨。结果表明，和普通干燥焙烧方法相比，微波法干燥焙烧球团矿温度上升迅速且内部温度分布均匀；干燥速度很快，干燥过程中不出现裂纹和爆裂现象；焙烧后的磁性球团矿主要由连晶充分的Ｆｅ_２Ｏ_３组成；每个成品球的强度为１７０～２３０ｋｇ；焙烧时不会出现过热．
Using 1400 / 850W microwave oven, the variation of pellet temperature, drying characteristics, green pellet strength and pellet lithofacies characteristics in microwave heating magnetite pellets were studied in the laboratory. The consolidation mechanism was also studied Exploring. The results showed that compared with the ordinary drying roasting method, the temperature of the microwave roasting and drying pellets increased rapidly and the internal temperature was evenly distributed. The drying speed was very fast and no cracks and bursting occurred during the drying. The magnetic pellets after roasting mainly By the crystal full Fe_2O_3 composition; the strength of each finished ball is 170 ~ 230kg; roasting does not appear overheating.
