Los filtros de aluminio para fundici\u00f3n se utilizan principalmente para filtrar aluminio y aleaciones de aluminio en fundiciones y salas de colada. Gracias a su excelente resistencia a la corrosi\u00f3n del aluminio fundido, pueden eliminar eficazmente las inclusiones, reducir el gas arrastrado y proporcionar un flujo laminar, lo que da como resultado un metal filtrado significativamente m\u00e1s limpio. Un metal m\u00e1s limpio se traduce en piezas de fundici\u00f3n de mayor calidad, menos desechos y menos defectos por inclusiones, lo que a su vez se traduce en un mayor beneficio neto.<\/p>\n

Los filtros de aluminio fundido est\u00e1n disponibles en todos los tama\u00f1os habituales: 7\u2033, 9\u2033, 12\u2033, 15\u2033, 17\u2033, 20\u2033 y 23\u2033.<\/p>\n

Ofrecemos toda la gama de porosidad, desde PPI 10 hasta PPI 60 (PPI = poros por pulgada). Tambi\u00e9n disponemos de filtros de corte individual.<\/p>\n

Los filtros de aluminio fundido est\u00e1n provistos de juntas perimetrales. La junta garantiza un ajuste correcto y herm\u00e9tico del filtro en la carcasa. Hay disponibles diferentes tipos de separadores: juntas de fibra cer\u00e1mica, juntas de algod\u00f3n expandido, etc. Adem\u00e1s, puedes elegir CFF-AL<\/a> sin la junta.<\/p>\n

\"Filtrado<\/p>\n

A la hora de instalarlo y utilizarlo, en general, hay que prestar atenci\u00f3n a los siguientes aspectos:<\/p>\n

1. Selecci\u00f3n correcta de las placas filtrantes: El tama\u00f1o de las placas filtrantes y el n\u00famero de orificios deben seleccionarse teniendo en cuenta el rango de caudal para el tipo espec\u00edfico de colada, el nivel m\u00e1ximo de l\u00edquido en el metal durante la filtraci\u00f3n, el volumen total de filtraci\u00f3n y la pureza del aluminio l\u00edquido original.
\n2. No se puede pasar por alto la filtraci\u00f3n previa a la fusi\u00f3n: por ejemplo, en los hornos de escoria convencionales y en la limpieza de los hornos de fusi\u00f3n y de mantenimiento de aluminio; as\u00ed como en el proceso de refinado en el horno. En particular, sigue siendo necesario un dispositivo de desgasificaci\u00f3n en l\u00ednea, ya que no solo reduce el contenido de hidr\u00f3geno en la masa fundida, sino que tambi\u00e9n elimina algunas inclusiones no met\u00e1licas.
\n3. La placa filtrante debe ajustarse al cuerpo cuadrado del filtro refractario: ambos est\u00e1n dise\u00f1ados para sellarse herm\u00e9ticamente, con el fin de evitar que el metal penetre en el cuerpo de fundici\u00f3n a trav\u00e9s del hueco sin pasar por el filtro, as\u00ed como para evitar que la placa filtrante de espuma flote en el aluminio fundido debido a su peso excesivamente ligero\u2026 Y fall\u00f3.
\n4. Precalentar antes de su uso: Precalentar para eliminar la humedad y facilitar la filtraci\u00f3n transitoria inicial. El precalentamiento puede realizarse mediante calefacci\u00f3n el\u00e9ctrica o de gas. En condiciones normales, esto tarda unos 15 minutos.
\n5. Durante la filtraci\u00f3n normal, no es necesario utilizar escoria para evitar los golpes y las vibraciones de la placa filtrante. Al mismo tiempo, el canal\u00f3n debe llenarse con agua de aluminio para evitar que esta se rompa en exceso.
\n6. Tras la colada, vac\u00ede el metal de la celda de flujo y de la placa filtrante. En el extranjero, se utiliza un vibrador que se coloca sobre la placa filtrante y se agita durante un minuto para eliminar aproximadamente 75% del metal l\u00edquido restante de la placa filtrante.
\n7. Por \u00faltimo, limpia el per\u00edmetro y retira la placa filtrante una vez que se haya secado.<\/p>","protected":false},"excerpt":{"rendered":"
