| Abstract Scope |
Molten blast furnace (BF) slag is a kind of high temperature liquid resource with abundant waste heat has not been recycled in iron and steel making industry. At present, the treatment of blast furnace slag is usually water quenching and air cooling accumulation. But, there are some disadvantages in this way to treatment of blast furnace slag, such as serious air pollution and high water consumption. This paper described the preparation of expanded slag ball with blast furnace slag by rotary cup. The effects of rotating speed, diameter of rotary cup and water content on particle size distribution, vitreous content and grindability of slag ball were studied. The blast furnace slag ball produced by this method can realize self-drying because of its own heat. It does not need follow-up dehydration, drying and other processes to save energy. |
