\n\t\t\t\tO aumento da limpeza inclusion\u00e1ria em a\u00e7os especiais impulsiona a pesquisa sobre a remo\u00e7\u00e3o e modifica\u00e7\u00e3o de inclus\u00f5es durante as etapas de refino do a\u00e7o l\u00edquido na aciaria. A diminui\u00e7\u00e3o da reoxida\u00e7\u00e3o durante a metalurgia do distribuidor se apresenta como um dos principais desafios para ind\u00fastria sider\u00fargica nos pr\u00f3ximos anos. Dessa forma, o Laborat\u00f3rio de Siderurgia da UFRGS realizou estudo visando avaliar a reoxida\u00e7\u00e3o do a\u00e7o l\u00edquido durante a metalurgia do distribuidor a partir de testes em escala laboratorial. Esse estudo foi o tema da disserta\u00e7\u00e3o de mestrado do Me.

\n\t\t\t\tAs intera\u00e7\u00f5es do a\u00e7o l\u00edquido com os materiais presentes no distribuidor (esc\u00f3ria de distribuidor, cinza de casca de arroz e massa refrat\u00e1ria) foram analisadas. O arranjo experimental (figura ao lado) foi definido a partir de uma revis\u00e3o da literatura sobre experimentos em escala de laborat\u00f3rio com foco nas rea\u00e7\u00f5es entre o a\u00e7o l\u00edquido e a esc\u00f3ria. A partir desta revis\u00e3o, os principais par\u00e2metros a serem controlados foram definidos. Al\u00e9m disso, a import\u00e2ncia de cada par\u00e2metro e os efeitos de sua modifica\u00e7\u00e3o foram avaliados. Os resultados experimentais foram comparados com a literatura e o equil\u00edbrio termodin\u00e2mico calculado pelo programa FactSage. A partir destas compara\u00e7\u00f5es houve a valida\u00e7\u00e3o do arranjo experimental, o qual serve atualmente como base para o planejamento de experimentos envolvendo a\u00e7o e esc\u00f3ria no Laborat\u00f3rio de Siderurgia da UFRGS.\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
