概述自第一座工业球团厂投产以来,至今已有三十多年历史了。在这三十多年中,虽然各国科学工作者对球团矿作为高炉优质原料的看法时有不同,但世界球团矿的总产量仍在不断增加。这种情况的出现,除了由于球团矿具有强度高、粒度均匀、还原性好和可以长期存放等公认的优点外,还和各国的资源条件有关。因为球团矿法适于处理细粒物料,所以,一些贫矿较多的国家,对发展球团矿仍有很大兴趣。 Overview Since the first industrial pellet plant was put into operation, it has been more than 30 years old. In these three decades, although scientists from all over the world have different views on pellets as high-quality raw materials for blast furnaces, the total output of pellets in the world is still on the rise. In addition to the well-established advantages of pellets such as high strength, uniform grain size, good reducibility and long-term storage, this situation is also related to the resource conditions in various countries. Because the pelleting method is suitable for handling fine-grained materials, some countries with more lean mines are still interested in the development of pellet mines.
