El filtro de espuma cer\u00e1mica Nikkeikin se instala en la m\u00e1quina CFF BOX para filtrar las impurezas del l\u00edquido presente en la aleaci\u00f3n de aluminio.<\/strong> para satisfacer las necesidades de producci\u00f3n de piezas de fundici\u00f3n de precisi\u00f3n de aleaciones de aluminio de alto valor a\u00f1adido y alto rendimiento tecnol\u00f3gico destinadas a los sectores de la aviaci\u00f3n y el transporte.<\/p>\n

En el proceso de fundici\u00f3n y moldeo del aluminio, la pureza del aluminio fundido est\u00e1 relacionada con la calidad metal\u00fargica del lingote.<\/strong>
\nEl m\u00e9todo de filtrado m\u00e1s habitual consiste en utilizar una placa filtrante para eliminar las impurezas del aluminio fundido. Por lo general, la pieza fundida se coloca directamente en la caja de filtrado para llevar a cabo el proceso.
\nLa caja filtrante para aluminio l\u00edquido es una herramienta auxiliar que puede mejorar esta situaci\u00f3n. Colocamos la placa filtrante en la caja filtrante para aluminio l\u00edquido. El aluminio fundido se filtra repetidamente a trav\u00e9s de varias capas de placas filtrantes, lo que mejora considerablemente las propiedades metal\u00fargicas del lingote.<\/p>\n

\"Filtro<\/p>\n

Escoria de oxidaci\u00f3n<\/strong>
\nAn\u00e1lisis de las causas de la oxidaci\u00f3n de las aleaciones de aluminio y de los defectos por inclusiones de escoria
\n1. El cargo no est\u00e1 claro y el importe de la devoluci\u00f3n es demasiado elevado.
\n2. No se elimina la escoria del l\u00edquido de la aleaci\u00f3n.
\n3. Tras el tratamiento de deterioro, el tiempo de reposo no es suficiente.
\nMedidas preventivas
\nUna vez que la carga ha sido detonada con arena, la carga de retorno se controla para que no se desv\u00ede en m\u00e1s de 70% de la masa de la carga.
\nRealice el degasaje y elimine completamente la escoria; tras el proceso de degradaci\u00f3n, aseg\u00farese de que haya un tiempo de reposo suficiente para que la escoria se hunda o flote.
\nUtiliza el filtro Casthouse para eliminar la escoria de \u00f3xido y otras escorias de aluminio.<\/p>\n

Nikkeikin ha adquirido Filter Foundry a trav\u00e9s de sales@adtechamm.com para la fundici\u00f3n en continuo.<\/strong>, equipos de filtraci\u00f3n de fundente para aluminio destinados a la colada semicontinua, la colada por gravedad y la colada a baja presi\u00f3n.
\nEl personal t\u00e9cnico de Alitalia considera que el filtro de espuma cer\u00e1mica es una herramienta eficaz para lograr la pureza metal\u00fargica del metal fundido durante el proceso de fundici\u00f3n. El filtro tambi\u00e9n permite estabilizar el llenado del molde, evitando as\u00ed defectos indeseables en la pieza fundida.<\/p>\n

El filtro de espuma cer\u00e1mica Nikkeikin suele utilizar espuma de poliuretano como soporte, que se sumerge en una pasta cer\u00e1mica compuesta por polvo fino (como agregados refractarios, agentes de sinterizaci\u00f3n, aglutinantes y agua), y a continuaci\u00f3n se extruye el exceso de pasta. El material cer\u00e1mico que rodea la fibra de espuma se seca, se cuece y se sinteriza a alta temperatura, y finalmente se obtiene el producto cer\u00e1mico de espuma.
\nDado que la temperatura de fundici\u00f3n de la aleaci\u00f3n es diferente, durante la fundici\u00f3n debe utilizarse un filtro cer\u00e1mico de espuma fabricado con material refractario.<\/p>\n

Para resolver este problema<\/strong>, se inserta en el sistema de colada un filtro sencillo, fabricado con malla met\u00e1lica, chapa de acero perforada, etc., para eliminar las impurezas desde el principio.
\nFiltro interior con estructura bidimensional, como fibras de silicato en forma de aguja y fibras de nitruro de boro.
\nHoy en d\u00eda, los filtros de espuma cer\u00e1mica aprovechan el tama\u00f1o de los poros para interceptar mec\u00e1nicamente las part\u00edculas grandes de \u00f3xido mixto, mientras que las capas de filtro se utilizan para filtrar las part\u00edculas peque\u00f1as de \u00f3xido mixto.
\nAdem\u00e1s, cuenta con funciones de adsorci\u00f3n y rectificaci\u00f3n. La l\u00ednea de producci\u00f3n que utiliza filtros de espuma cer\u00e1mica ha aumentado considerablemente la producci\u00f3n de piezas fundidas.<\/p>","protected":false},"excerpt":{"rendered":"
