摘　　要：本文系统介绍了国内外铁矿球团理论与技术的进展,包括球团矿的产量、生产工艺、球团原料制备、粘结剂及产品品种。球团矿的发展将不仅体现在其产量的进一步增长,而且球团矿品种也将更加丰富,除酸性球团矿外,将生产更多种类的球团矿,如镁质球团矿、自熔性球团矿。此外,原料来源复杂也对球团生产发展带来更大挑战。The recent progress in theory and technology of iron ore pelletization is introduced, including the woad output of fired pellets, the pellet production processes, preparation of pellet feed, binders and the varieties of pellets. The big progress in iron ore pelletization is not only embodied in the dramatic growth of pellet output, but also in the variety of pellet products. Besides traditional acid pellets, more types of fired pellets for example magnesium - bearing pellet and self - fluxing pellet are produced. In addition, the application of complex and refractory pellet feed will bring more challenges to the pelletizing industry.
