Filtros de espuma cer\u00e1mica<\/a> proporcionan una eliminaci\u00f3n rentable y fiable de las inclusiones del aluminio fundido.
\nEl nivel exacto de eficacia en la eliminaci\u00f3n de impurezas puede variar considerablemente en funci\u00f3n de la aplicaci\u00f3n.
\nPor lo general, la eficiencia aumenta a medida que disminuye el tama\u00f1o de las celdas del filtro y la velocidad del metal a su paso por el filtro.
\nLa composici\u00f3n cer\u00e1mica combina una elevada resistencia mec\u00e1nica, una excelente resistencia al aluminio fundido y unas excelentes propiedades t\u00e9rmicas.
\nEsta combinaci\u00f3n de caracter\u00edsticas f\u00edsicas lo hace ideal para su uso en todo tipo de operaciones de fundici\u00f3n.<\/p>\n![\"Filtro](\"http:\/\/www.adtechamm.com\/wp-content\/uploads\/2019\/10\/Porous-Alumina-Ceramic-Filter.jpg\")

Filtro cer\u00e1mico de al\u00famina porosa metal\u00fargica para piezas de fundici\u00f3n en molde<\/p>\n
El filtro cer\u00e1mico de al\u00famina porosa presenta una estructura cer\u00e1mica homog\u00e9nea t\u00edpica, con un n\u00famero m\u00ednimo de zonas obstruidas tanto en las dos caras como en el interior del filtro.
\nEstos filtros, gracias a su resistencia a los productos qu\u00edmicos utilizados en las plantas metal\u00fargicas y a su resistencia t\u00e9rmica a temperaturas de 1350 \u00b0C, ofrecen unas condiciones \u00f3ptimas para la filtraci\u00f3n durante todo el proceso de fundici\u00f3n.
\nSu composici\u00f3n qu\u00edmica, junto con la fuerza de adhesi\u00f3n que act\u00faa en el interior de la cer\u00e1mica del filtro, resulta ideal para retener impurezas, especialmente las basadas en A1203.<\/p>\n
Filtros metal\u00fargicos: tienen forma cuadrada y redonda con bordes biselados, lo que garantiza su correcta colocaci\u00f3n en los dep\u00f3sitos de filtrado horizontales.
\nLos filtros para aplicaciones verticales se fabrican con forma cuadrada u otras formas especiales, sin bordes biselados.<\/p>\n
Se recomienda que todos los tipos de filtros est\u00e9n provistos de una junta de estanqueidad o expansible para garantizar una fijaci\u00f3n adecuada en los revestimientos y las cajas de filtro.
\nLos filtros metal\u00fargicos deben precalentarse antes de la filtraci\u00f3n.
\nDe este modo, se consigue la m\u00e1xima velocidad de filtraci\u00f3n y de colada.<\/p>\n
Los filtros perfilados se utilizan en el sistema de cierre de los moldes, as\u00ed como para la colada directa sobre el filtro en combinaci\u00f3n con manguitos exot\u00e9rmicos o tapas aislantes.<\/p>\n
En la fundici\u00f3n por enfriamiento a baja presi\u00f3n se utilizan formas de filtro especialmente dise\u00f1adas, los denominados \u201ctapones\u201d, en combinaci\u00f3n con tubos de cer\u00e1mica.
\nLos \u201ctapones\u201d se equipan con una junta expansible y, a continuaci\u00f3n, se introducen en los tubos.<\/p>","protected":false},"excerpt":{"rendered":"
