Dado que las inclusiones y el hidr\u00f3geno presentes en el aluminio fundido van de la mano e interact\u00faan entre s\u00ed, los distintos m\u00e9todos basados en la eliminaci\u00f3n del hidr\u00f3geno y la purificaci\u00f3n tambi\u00e9n presentan diferentes grados de eliminaci\u00f3n de impurezas. Sin embargo, la pr\u00e1ctica demuestra que este tipo de efecto de eliminaci\u00f3n de impurezas es muy limitado. En la actualidad, no existen muchos m\u00e9todos de purificaci\u00f3n del aluminio que permitan eliminar las impurezas de forma eficaz. La investigaci\u00f3n en este \u00e1mbito no es tan exhaustiva como la dedicada a la purificaci\u00f3n mediante eliminaci\u00f3n de hidr\u00f3geno, y los m\u00e9todos principales son el m\u00e9todo del fundente, el m\u00e9todo del fundente el\u00e9ctrico y el m\u00e9todo de filtraci\u00f3n.<\/p>\n

M\u00e9todos de purificaci\u00f3n del aluminio<\/strong><\/p>\n

La esencia de la m\u00e9todo del flujo<\/a> es que, cuando el aluminio fundido se purifica mediante el fundente, las inclusiones migran espont\u00e1neamente desde la masa fundida hacia el fundente debido a la diferencia en la temperatura de transici\u00f3n entre las fases en contacto. Su efecto de eliminaci\u00f3n de impurezas est\u00e1 directamente relacionado con las propiedades f\u00edsicas y qu\u00edmicas del propio fundente. Al mismo tiempo, las condiciones del proceso de purificaci\u00f3n \u2014como la cantidad de fundente, las condiciones de contacto entre el fundente y el ba\u00f1o de fusi\u00f3n, y la temperatura\u2014 a\u00fan no se han determinado en un programa a gran escala.<\/p>\n

El m\u00e9todo del flujo el\u00e9ctrico es un m\u00e9todo de purificaci\u00f3n desarrollado por la antigua Uni\u00f3n Sovi\u00e9tica a partir de la d\u00e9cada de 1970. Su principio b\u00e1sico consiste en eliminar de forma continua las impurezas del aluminio fundido bajo la acci\u00f3n de un campo el\u00e9ctrico de corriente continua o alterna.<\/p>\n

\"M\u00e9todos<\/p>\n

La purificaci\u00f3n mediante filtraci\u00f3n consiste principalmente en hacer que el aluminio l\u00edquido fluya a trav\u00e9s de un medio determinado, de modo que este capture las inclusiones seg\u00fan un mecanismo concreto y, al mismo tiempo, elimine el hidr\u00f3geno adsorbido en las impurezas para lograr el objetivo de la purificaci\u00f3n. Se trata de uno de los m\u00e9todos eficaces para eliminar las inclusiones. Seg\u00fan el tipo de filtro, se puede dividir en tres categor\u00edas: filtro de malla, filtro granular y filtro cer\u00e1mico poroso; entre ellos, el filtro cer\u00e1mico poroso se subdivide en cer\u00e1mica r\u00edgida (microporosa) y filtro cer\u00e1mico de espuma<\/a>. Seg\u00fan el mecanismo de filtraci\u00f3n, se puede clasificar en filtraci\u00f3n por torta de filtro y filtraci\u00f3n profunda. La cer\u00e1mica porosa pertenece a la filtraci\u00f3n profunda.<\/p>","protected":false},"excerpt":{"rendered":"
