Abstract

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.
