Abstract

This work aims at the use of computational thermodynamics in the study of desulfurization of pig iron through CaO-Fluorspar and CaO-Sodalite mixtures. Experiments were performed with the addition of different mixtures from these systems in molten pig iron at a temperature of 1,400ºC. The test results were analyzed and compared with those obtained by the computational thermodynamics software program THERMOCALC. Through this software, were calculated the equilibrium sulfur content in the metal, solid phases, and the amount of liquid in each desulfurizing mixture used in the process at a temperature of 1,400ºC. The computational thermodynamics proved to be an effective tool in predicting the desulfurization capacity of the mixtures.Esse trabalho tem como objetivo o uso da termodinâmica computacional no estudo de dessulfuração de ferro-gusa com misturas de CaO-Fluorita e CaO-Sodalita. As experiências foram realizadas com a adição de diferentes misturas a partir desses sistemas em ferro-gusa a uma temperatura de 1,400ºC. Os resultados do teste foram analisados e comparados com os obtidos pelo programa de termodinâmica computacional THERMOCALC. Através deste software, foi calculado o teor de equilíbrio de enxofre do metal, as fases sólidas presentes e a quantidade de líquido em cada uma das misturas dessulfurantes utilizadas no processo na temperatura de 1,400ºC. A termodinâmica computacional provou ser uma ferramenta eficaz para estimar a capacidade de dessulfuração das misturas.
