Abstract The ejection of metal droplets into slag due to top-blowing is characteristic the BOF process. residence time in plays a significant role kinetics metal–slag reactions. In this study, ejected during steelmaking investigated and various approaches, based on blowing number theory mass balances are compared. Previously published theories evaluated comparison with physically upper lower bo...

In order to reduce CO2 emission, the sequestration using particulate steelmaking slag in water is world widely being studied through a Ca-carbonation method. As consequence, improved efficiency of Ca leaching from steelmaking-slag particles contributes significantly increasing amount fixed CO2. Therefore, this study, for purpose understanding particles, rate week acidic solution was analyzed by...
