泉华潮湿的适当内容和分发在铁矿石的使成粒状起一个重要作用。在这研究，孔，尺寸分发，和粒子的效果在铁矿石的四种类型的水吸收率(战争) 上塑造被使用沉浸方法和毛状的水吸收分析方法。另外，在铁矿石位于水吸收过程下面的机制被解开。铁矿石的战争在水吸收的起始的阶段随水吸收时间的增加快速减少，这被发现。随吸收时间的另外的增加，战争逐渐地减少，直到在 0 附近。有更高的孔，更小的粒子尺寸，和像板的结构的铁矿石有更高的战争。与在单个粒子的铁矿石的毛孔相比，在在多粒子氧化铁的粒子之中的虚空在水吸收的起始的阶段起一个重要作用。单个粒子的所有和在这研究分析的多粒子铁矿石的水吸收机制包括四步，开始的三步在那里在 sintering 过程起一个重要作用。

英文摘要：

The appropriate content and distribution of sinter moisture play an important role in the granulation of iron ores. In this study, the effects of porosity, size distribution, and particle shape on the water absorption rate （WAR） of four types of iron ores were analyzed by using the immersion method and capillary water absorption method. In addition, the mechanism underlying the water absorption process in iron ores was unraveled. It is found that the WARs of iron ores decrease quickly with the increase in water absorption time at the initial stages of water absorption. With further increase in absorption time, the WARs decrease gradually, until near 0. Iron ores with higher porosity, smaller particle size, and plate-like structure have the higher WARs. Compared with pores in the single-particle iron ore, voids among particles in the multi-particle iron oxide play an important role at the initial stages of water absorption. The water absorption mechanism of all single-particle and multi-particle iron ores analyzed in this study includes four steps, wherein the first three steps play a significant role in the sintering pro-cess.
