Resumo
The aim of this work was to study the use of slags to desulfurization of cast iron. It was proposed to use alumina instead fluorspar. In addition, marble waste was used instead lime. Simulations applying Thermo-Calc software were performed in order to obtain the theoretical phases thermodynamic data. Then, a comparison between theoretical data and experimental tests were performed. The cast iron was melting in induction furnace at 1550°C. Slags composed mainly for CaO and Al2O3 were used to cast iron desulphurization. It was observed that increasing liquid phase, the desulphurization reaction was favored. Besides, it was found that cast iron desulfurization occurs by top slag mechanism.
