Abstract
LA INVENCION SE REFIERE A UN PRODUCTO PARA LA DESULFURACION DE LAS FUNDICIONES, CONSTITUIDO ESENCIALMENTE POR UNA MEZCLA DE GRANOS DE CARBURO DE CALCIO Y DE MAGNESIO. LOS GRANOS DE MAGNESIO ESTAN REVESTIDOS DE UNA CAPA DE PRODUCTO MINERAL AÑADIDO A UN LIGANTE. PREFERENTEMENTE, EL PRODUCTO MINERAL QUE REVISTE AL MAGNESIO ES TAMBIEN CARBURO DE CALCIO. LOS DIAMETROS DE LOS GRANOS DE MAGNESIO Y DE CARBURO DE CALCIO SE ELIGEN DE MANERA QUE SEAN PROPORCIONALES A LAS MASAS VOLUMINICAS MEDIAS DE LOS GRANOS DE MAGNESIO REVESTIDOS Y DE LOS GRANOS DE CARBURO DE CALCIO. LOS GRANOS DE CARBURO DE CALCIO PUEDEN ESTAR ELLOS MISMOS DE GRANOS MAS FINOS AGLOMERADOS POR UN LIGANTE. EL LIGANTE ES PREFERENTEMENTE UN ESTER GRASO, CON PUNTO DE FUSION FRANCO Y RELATIVAMENTE ELEVADO. LA MEZCLA DESULFURANTE SEGUN LA INVENCION SE INYECTA CON LA LANZA EN LOS BAÑOS DE FUNDICION. TIENE LA VENTAJA DE SER MENOS REACTIVO RESPECTO DE LA HUMEDAD Y DE NO SEGREGARSE DURANTE EL TRANSPORTE Y DEL ALMACENAMIENTO.
