Los filtros de espuma cer\u00e1mica para la filtraci\u00f3n en la fundici\u00f3n de aluminio suelen describirse como un mecanismo de interceptaci\u00f3n, capa de sedimentos y filtraci\u00f3n profunda.<\/p>\n

Filtros de espuma cer\u00e1mica para la fundici\u00f3n de aluminio<\/strong><\/p>\n

1. El efecto de una capa de lodos o de una capa de torta de filtraci\u00f3n, con la deposici\u00f3n de part\u00edculas en la masa fundida y en las uniones entrelazadas y curvadas de la malla, mejora la capacidad de capturar part\u00edculas de fase.
\n2. La superficie rugosa formada por los huecos de la estructura de malla aumenta la superficie de contacto entre el flujo de aluminio l\u00edquido y la superficie cer\u00e1mica s\u00f3lida, lo que favorece la presencia de part\u00edculas en el flujo de aluminio l\u00edquido.
\nLa direcci\u00f3n del flujo auxiliar es m\u00e1s desordenada, lo que favorece la recogida y la sedimentaci\u00f3n de los s\u00f3lidos.
\n3. Debido a las grietas microsc\u00f3picas y los poros min\u00fasculos presentes en la superficie del marco de malla, se deposita previamente un fundente de fluoruro con una fuerte afinidad por part\u00edculas como el Al\u2082O\u2083.
\nEl efecto global de la torta de filtraci\u00f3n y la fuerte fuerza de quimisorci\u00f3n aumentan la capacidad de capturar part\u00edculas heterog\u00e9neas retenidas.<\/p>\n

\"Filtros<\/p>\n

El l\u00edquido filtro de espuma de aluminio y cer\u00e1mica<\/a> Es el filtro m\u00e1s utilizado en el \u00e1mbito de la filtraci\u00f3n del aluminio fundido. Sus ventajas son su elevada porosidad, su alta eficiencia de filtraci\u00f3n, su facilidad de sustituci\u00f3n, su bajo coste y su facilidad de fabricaci\u00f3n; adem\u00e1s, mediante la filtraci\u00f3n de las inclusiones s\u00f3lidas tambi\u00e9n se puede separar una parte de las inclusiones l\u00edquidas.<\/p>\n

El proceso moderno de purificaci\u00f3n del aluminio fundido<\/a>, el filtro est\u00e1 a punto de finalizar el \u00faltimo proceso de limpieza de la pieza fundida.<\/p>\n

Antes de esto, tras refinado por flujo<\/a> en el horno, en reposo, con medio y sin medio de adsorci\u00f3n; aunque ya se hab\u00edan eliminado las inclusiones y el gas de los aceros 60% a 80%, la masa fundida segu\u00eda dispersando material m\u00e1s fino (di\u00e1metro de grano normalmente <15 \u03bcm) (incluidas las inclusiones de materia prima secundaria procedentes de la tolva y del contrato de producci\u00f3n intermedio).<\/p>\n

Para obtener productos de aluminio de alta calidad, debemos asegurarnos de que estas peque\u00f1as inclusiones se recojan y se separen mediante adsorci\u00f3n.<\/p>\n

En comparaci\u00f3n con otros m\u00e9todos de purificaci\u00f3n, el m\u00e9todo de filtraci\u00f3n se ha convertido en el m\u00e9todo preferido para la purificaci\u00f3n final del aluminio fundido debido a su bajo consumo energ\u00e9tico, su facilidad de manejo, su alta eficiencia de purificaci\u00f3n y su menor generaci\u00f3n de contaminaci\u00f3n secundaria.<\/p>","protected":false},"excerpt":{"rendered":"
