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, la purificaci\u00f3n del aluminio fundido es una etapa esencial.<\/p>\n

Hay muchas causas que provocan la contaminaci\u00f3n por aluminio. Por un lado, cuando se expone a la atm\u00f3sfera en el horno en estado fundido o semifundido durante el proceso de fundici\u00f3n, se oxida f\u00e1cilmente y reacciona con el vapor de agua para absorber arg\u00f3n, y tiende a formar diversos tipos de escoria no met\u00e1lica, como fragmentos del revestimiento del horno. En cuanto a los cloruros, carburos, etc., presentes en el fundente, y a las part\u00edculas intermet\u00e1licas gruesas, etc., parte de los residuos que constituyen la carga aporta algunas impurezas no alum\u00ednicas durante el proceso de circulaci\u00f3n. Dado que los residuos proceden de los residuos de proceso, los residuos generales y los residuos externos de cada proceso de la f\u00e1brica, su procedencia es diversa, su composici\u00f3n es compleja y su calidad es deficiente. Las impurezas mencionadas anteriormente suelen provocar burbujas e inclusiones en la palanquilla de fundici\u00f3n, lo que afecta gravemente a la pureza del metal fundido, lo que a su vez repercute en el rendimiento del procesamiento, las propiedades mec\u00e1nicas, la resistencia a la corrosi\u00f3n y la calidad est\u00e9tica del producto.<\/p>\n

El filtro cer\u00e1mico de espuma de al\u00famina<\/a> La placa es capaz de eliminar eficazmente diversas impurezas presentes en el aluminio fundido con una finura del orden de los micr\u00f3metros, de modo que el flujo de aluminio fundido se convierte en un flujo laminar uniforme, lo que favorece el llenado. Presenta una estructura \u00fanica de porfirita-corind\u00f3n, buena resistencia mec\u00e1nica y estabilidad qu\u00edmica, as\u00ed como una resistencia superior a la erosi\u00f3n del aluminio fundido. El tama\u00f1o de los orificios y la tasa de perforaci\u00f3n, estrictamente controlados, permiten obtener un efecto de filtrado estable. La placa filtrante de cer\u00e1mica celular est\u00e1 rodeada por un revestimiento de fibra cer\u00e1mica de sellado, lo que ayuda a sellar la placa en la caja del filtro y garantiza que no se produzca ning\u00fan flujo lateral de metal fundido. Este producto se utiliza principalmente en el proceso de purificaci\u00f3n de la producci\u00f3n de aluminio y aleaciones de aluminio, as\u00ed como en diversos medios de separaci\u00f3n gas-s\u00f3lido y l\u00edquido-s\u00f3lido, soportes de catalizadores, quemadores, absorci\u00f3n ac\u00fastica y protecci\u00f3n medioambiental.<\/p>\n

\"Purificaci\u00f3n<\/p>\n

Las placas filtrantes de espuma cer\u00e1mica para la purificaci\u00f3n del aluminio fundido han aportado enormes beneficios a la producci\u00f3n de l\u00e1minas y a sus productos derivados (como las piezas en bruto para latas y las planchas de impresi\u00f3n de PS). Para los fabricantes de perfiles de aleaci\u00f3n de aluminio, existen varias ventajas evidentes:<\/p>\n

1. Mejorar la productividad de la extrusi\u00f3n: al utilizar placas filtrantes para purificar las piezas en bruto de extrusi\u00f3n de la aleaci\u00f3n 6063, la velocidad de extrusi\u00f3n aumenta en aproximadamente un 20% y la productividad se incrementa en casi un 15%.
\n2. Prolongar la vida \u00fatil del molde y reducir el n\u00famero de reparaciones del mismo.
\n3. Reducci\u00f3n de la fuerza de extrusi\u00f3n: cuando la aleaci\u00f3n 6063 fundida se purifica mediante la placa filtrante, se observa que la fuerza de extrusi\u00f3n se reduce en un 3% m\u00e1s que en el caso del material sin filtrar.
\n4. Mejorar notablemente la calidad de la superficie de los perfiles de aluminio.<\/p>","protected":false},"excerpt":{"rendered":"
