Current and Future of Dry Centrifugal Granulation Process

Abstract

At present, water-quenching process takes the leading role in steel industry. Apparently, this method not only consumes lots of water, but also has little waste heat recovered, as well as the atmosphere polluted on account of releasing H2S etc. Dry centrifugal granulation ( DCG ) process, as an environmentally friendly method with high-efficiency heat recovery, draws more attentions in recent years,which is the optimum process, with smaller slag particle size (about 2mm), more glassy phase and higher recovery rate. After a thorough comparative analysis of the various research, the problem presented in this mothed is of vital importance for commercialization.
