Based on the comprehensive experimental test-bed of blast furnace slag waste heat recovery, we study the impacts which are caused by the changes of the key parameters, such as blast furnace slag discharged temperature, the speed of the granulation device, on the particle diameter distribution and sphericity, so as to master the best operating parameters of the blast furnace slag dry granulation, and provide experimental basic materials for blast furnace slag waste heat recovery. The results show that: when the discharged temperature of the blast furnace slag is controlled in 1400°C～1450°C, and the speed of the granulation device is controlled above 2000r/min, the sphericity is better, and 80% of the particle’s diameter will be 2～5mm.

Furnace Slag

The molten blast furnace slag (BF slag) is discharged at the temperature of about 1400-1550 °C, which contains a large amount of heat. At present, water quenching is the main technology to treat the BF slag, but this method not only consumes a huge amount of water, but also fails to recover the waste heat. Compared with water quenching, the dry centrifugal granulation has obvious advantages. There is no water consumed and the waste heat can be recovered efficiently, thus this technology has great potential. This technology mainly contains two processes: the granulating process and the heat recovery process. The present development statuses on those two processes are summarized respectively and the prospect of dry centrifugal granulation technology is forecasted.
