Abstract

West Japan Works (Fukuyama) of JFE steel have two sinter plants. Fukuyama #4 sinter plant (Suction area: 454 m2) is normal plants. It means that #4 sinter plant don’t have HPS plant. And Fukuyama #5 sinter plant (Suction area: 605 m2) have HPS(Hybrid Pelletized Sinter) plant. We make always improvement of sinter productivity and quality. This paper reports several contents of our improvement. Summary is follows. i) JFE has developed an advanced granulation process for the treatment of raw mixtures, named "Clear (Coke breeze and Limestone External Addition for Reactivity) Process". We introduced Clear process in Fukuyama #5 sinter plant. Probably, combination of HPS and Clear process is the first time. As the results, productivity increase about 3% with the improvement of granulation size; ii) we are making improvement of the operation precision. We try to improve the BTP (Burn trough point) control again. As the results, productivity increase about 2% with the improvement of quality deviation.
