La filtraci\u00f3n del metal fundido es una pr\u00e1ctica habitual en la industria. En concreto, el uso de filtros de espuma de malla para filtrar aluminio fundido se ha generalizado ampliamente en este \u00e1mbito. Como todos sabemos, la resistencia al fuego y la estabilidad qu\u00edmica del material filtrante son esenciales para lograr una filtraci\u00f3n eficaz de las part\u00edculas de inclusiones y para evitar que los productos de reacci\u00f3n del material filtrante se liberen como contaminantes en el metal fundido.<\/p>\n

El uso de s\u00edlice como material refractario en espuma ser\u00eda recomendable, ya que suele ser econ\u00f3mico y f\u00e1cil de procesar. La s\u00edlice tambi\u00e9n presenta una baja expansi\u00f3n t\u00e9rmica y un bajo m\u00f3dulo de compresi\u00f3n. Lamentablemente, se sabe que tiene una alta reactividad en aleaciones de aluminio fundido, especialmente en aquellas que contienen magnesio.<\/p>\n

La s\u00edlice presente en el material particulado del filtro de espuma reticulada se corroe f\u00e1cilmente en contacto con el aluminio o el magnesio. Evita utilizar s\u00edlice al filtrar aluminio fundido, magnesio o sus aleaciones.<\/p>\n

Desde hace tiempo existe la necesidad de disponer de un material refractario que sea relativamente econ\u00f3mico, resistente en condiciones de filtraci\u00f3n, no reactivo y que pueda utilizarse con diversas aleaciones de aluminio, en particular con aquellas que contienen magnesio.<\/p>\n

\"Filtro<\/p>\n

Los filtros de espuma reticulada que utilizan part\u00edculas de \u00e1rido de al\u00famina se han utilizado habitualmente para filtrar aluminio y aleaciones de aluminio. Sinterizados de alta pureza, aglomerados filtros de al\u00famina<\/a> Tambi\u00e9n son bien conocidos los sistemas de filtrado que utilizan ligantes de hidrato de al\u00famina. Estos filtros presentan una excelente resistencia qu\u00edmica a los ataques del magnesio.<\/p>\n

Los filtros de espuma cer\u00e1mica dise\u00f1ados espec\u00edficamente por AdTech est\u00e1n fabricados con \u00f3xido de aluminio como materia prima b\u00e1sica. Nuestro filtro de espuma cer\u00e1mica de al\u00famina utiliza espuma de alta calidad y cer\u00e1mica de gran pureza como materia prima, y es capaz de eliminar eficazmente las impurezas s\u00f3lidas no met\u00e1licas del aluminio fundido y las aleaciones de aluminio en su industria de fundici\u00f3n de aluminio.<\/p>\n

Se fabrican con porosidades que oscilan entre 10 y 60 poros por pulgada (PPI). Adem\u00e1s, los juegos combinados se fabrican con una porosidad de 20-30 PPI, aunque existen otras opciones disponibles. Se fabrican filtros de diferentes tama\u00f1os y a medida seg\u00fan las especificaciones del cliente.<\/p>","protected":false},"excerpt":{"rendered":"
