Filtros de espuma cer\u00e1mica de al\u00famina<\/a> Se instalan en la m\u00e1quina CFF BOX para filtrar las impurezas l\u00edquidas de la aleaci\u00f3n de aluminio, con el fin de cumplir con los requisitos de alto valor a\u00f1adido y alto rendimiento tecnol\u00f3gico de la producci\u00f3n de piezas de fundici\u00f3n de precisi\u00f3n de aleaci\u00f3n de aluminio para los sectores de la aviaci\u00f3n, el transporte y otros.<\/p>\nLos fabricantes de agentes filtrantes para la fundici\u00f3n de aluminio deben tener en cuenta que la calidad del aluminio fundido es muy importante, ya que influye en gran medida en el rendimiento de los procesos posteriores y en la calidad del producto final. Por ello, todos los pa\u00edses del mundo se esfuerzan por purificar el aluminio fundido.<\/p>\n
Existen muchas causas de la contaminaci\u00f3n por aluminio. Por un lado, durante el proceso de fundici\u00f3n, el aluminio queda expuesto a la atm\u00f3sfera dentro del horno en estado fundido o semifundido, lo que facilita su oxidaci\u00f3n, su reacci\u00f3n con el vapor de agua para absorber hidr\u00f3geno y la formaci\u00f3n de diversos tipos de escoria no met\u00e1lica (como restos del revestimiento del horno, cloruro, carburo en el fundente, etc.) y part\u00edculas intermet\u00e1licas gruesas.<\/p>\n
Por otra parte, se introducir\u00e1n algunas impurezas que no son de aluminio en los residuos que componen la carga del horno.<\/p>\n
Dado que los residuos proceden de los residuos de proceso, los residuos geom\u00e9tricos y otros materiales de desecho de diversos procesos de la f\u00e1brica, su origen es variado, su composici\u00f3n es compleja y su calidad es deficiente.<\/p>\n
Estas impurezas suelen provocar la formaci\u00f3n de burbujas e inclusiones en la plancha, lo que afecta gravemente a la pureza del metal fundido y, a su vez, repercute en la procesabilidad, las propiedades mec\u00e1nicas, la resistencia a la corrosi\u00f3n y la calidad est\u00e9tica del producto.<\/p>\n
Hoy en d\u00eda, existen muchas formas de eliminar estas sustancias nocivas y purificar el aluminio fundido.<\/p>\n
Seg\u00fan los distintos m\u00e9todos, estos pueden clasificarse en dos tipos: el tratamiento en horno y el tratamiento continuo externo (es decir, el tratamiento en l\u00ednea).<\/p>\n
Seg\u00fan su funci\u00f3n, se puede dividir en dos tipos: desgasificaci\u00f3n o eliminaci\u00f3n de escoria. Los fabricantes de filtros cer\u00e1micos para fundici\u00f3n han introducido la filtraci\u00f3n continua del aluminio fundido mediante placas filtrantes de cer\u00e1mica celular. En el tratamiento continuo externo, la principal operaci\u00f3n de purificaci\u00f3n consiste en eliminar la escoria.<\/p>\n
El filtro cer\u00e1mico utilizado en la fundici\u00f3n presenta una estructura de malla resistente, capaz de soportar la influencia de la diferencia de presi\u00f3n entre la superficie del metal y el flujo de metal, aunque es fr\u00e1gil y quebradizo. Gracias a su estructura precisa, su masa uniforme y su gran superficie, el efecto de filtraci\u00f3n es excelente.<\/p>","protected":false},"excerpt":{"rendered":"
