The mechanism of lime dissolution in steelmaking slag and the factors that influence rate are highly significant improving efficiency process; however, they yet to be fully understood. Here, effects Al2O3/TiO2/Na2O additives on composition molten were investigated using a rotating cylinder technique. results indicate promotion coefficients at 1400 °C decrease order Na2O > TiO2 Al2O3. Further...

The article presents the results of mechanical activation steel-smelting slag affecting properties gypsum composition. As a result study, parameters were identified that characterize reactivity during activation. It was established increase in number Bronsted active adsorption centers on surface formed powders is responsible for their reactivity. However, maximum activity leads to large percent...
