Abstract

The mechanism of lime dissolution in steelmaking slag and the factors that influence the dissolution rate are highly significant in improving the efficiency of the steelmaking process; however, they are yet to be fully understood. Here, the effects of Al2O3/TiO2/Na2O additives on the dissolution rate of lime and the composition of molten slag were investigated using a rotating cylinder technique. The results indicate that the promotion coefficients at 1400 °C decrease in the order of Na2O > TiO2 > Al2O3. Furthermore, the CaO dissolution rate and kinetic parameters were calculated, and the lime dissolution mechanisms in the presence or absence of Al2O3, TiO2, and Na2O were compared. Additionally, the data show that ATN (a mixture with a mass ratio of Al2O3:TiO2:Na2O = 15:4:3) can be used as a suitable flux in the steelmaking process.
