    • A process for producing fired pellets by granulating finely-ground iron ore and subjecting the resulting granules sequentially to drying, dehydration, preheating, and firing, wherein said process comprises adding an additive to said finely-ground iron ore at the time of granulation, said additive reacting with iron ore to form a compound which has a melting point lower than the preheating temperature. Owing to the additive (or sintering auxiliary) added in a small amount to iron ore powder, it is possible to produce preheated pellets by using the existing grate kiln without increasing the amount of preheating energy. The resulting preheated pellets have improved strength and produce no adverse effect on finished pellets.
    • 一种生产烧制球团矿的方法,该方法是将细磨的铁矿石制粒并将所得颗粒依次进行干燥,脱水,预热和烧制,其中所述方法包括在造粒时向所述细磨铁矿石中加入添加剂, 添加剂与铁矿石反应形成熔点低于预热温度的化合物。 由于添加剂(或烧结辅助剂)少量添加到铁矿石粉末中,可以通过使用现有的炉排窑而不增加预热能量来生产预热颗粒。 所得到的预热颗粒具有改善的强度并且对成品颗粒不产生不利影响。
