| Abstract: | A considerable amount of heat energy is contained in the molten slag tapped from blast furnace. At present, the BF slag is treated by impinging much water for granulation and the energy is wasted without recovery. Thus, dry granulation technology has attracted more and more attention. The basic problems and technical difficulties of dry granulation were analyzed. Typical dry granulation processes for heat recovery were introduced according to the different granulation methods. Recent progresses such as Rotary Cup Atomizer (RCA) for slag granulation and heat recovery using methane steam reforming reaction were also presented. Finally, the application of heat recovery techniques into industry was forecasted. |
