Abstract
MéTODO CORRELACIONADO à PRODUçãO DE AçO. A presente invenção refere-se a um método para produção de um agente fundente, o qual pode ser usado na produção de aço, preferencialmente, aço inoxidável, caracterizado pelo fato de que é utilizada como matéria-prima para a produção do dito agente fundente uma borra de hidróxido, resultante da neutralização de líquido de decapagem contaminado de metal, proveniente de uma etapa de decapagem de um aço, a dita borra de hidróxido contendo pelo menos um composto contendo fluoreto e em que a dita borra de hidróxido é calcinada. A invenção também se refere a um método correlacionado à produção de aço, preferencialmente, aço inoxidável, compreendendo a produção de uma corrida de aço e descarburização da corrida de aço, pelo que é formada uma escória na parte superior da dita corrida de aço, caracterizado pelo fato de que é adicionado um produto de acordo com a invenção à dita escória. A invenção também se refere ao produto produzido de acordo com a invenção.
