Abstract

Abstract

In order to recycle Zn-bearing dusts in Baosteel, hot metal desiliconization with the dust was investigated in laboratory. The factors which affect desiliconization and Zn evaporation were discussed. Theresults show that the mixture of EAF dust and BOF dust containing Zn for hot metal desiliconization at 1500℃is better than sinter dust. The Zn evaporation rate in the slag can reach to 99 % and the height of foaming slag in desiliconization is lower. It benefits desiliconization by increasing temperature, enhancing stirring intensity or increasing the initial content of [Si].
