Diversos estudios han demostrado que, adem\u00e1s de eliminar las escorias, el filtro cer\u00e1mico moldeado tambi\u00e9n puede reducir el contenido de hidr\u00f3geno en el aluminio fundido. Gracias a su gran eficacia en la eliminaci\u00f3n de escorias, su sencillo funcionamiento, su f\u00e1cil integraci\u00f3n con otros componentes y su bajo coste, se ha convertido en un m\u00e9todo de purificaci\u00f3n habitual en la industria del procesamiento del aluminio.<\/p>\n

La producci\u00f3n de aluminio comprende la extracci\u00f3n de bauxita, la producci\u00f3n de al\u00famina, la electr\u00f3lisis del aluminio, la fundici\u00f3n y el moldeado, as\u00ed como otras fases del proceso.<\/p>\n

En primer lugar, se extrae el mineral de bauxita y, mediante procesos como el lavado con agua y la molienda, se obtiene polvo de mineral de aluminio; a continuaci\u00f3n, se obtiene al\u00famina mediante cuatro procesos complejos, entre los que se incluye el calcinado.<\/p>\n

Los fabricantes de al\u00famina han adoptado diferentes procesos de producci\u00f3n, entre los que destacan principalmente el proceso Bayer, el proceso de sinterizaci\u00f3n con cal sodada y el proceso combinado Bayer-sinterizaci\u00f3n. Por lo general, la bauxita de alta ley se produce mediante el m\u00e9todo Bayer, mientras que la bauxita de ley media y baja se produce mediante el m\u00e9todo combinado o el m\u00e9todo de sinterizaci\u00f3n. Debido a la sencillez de su proceso y a su bajo consumo energ\u00e9tico, el proceso Bayer se ha convertido en el m\u00e9todo m\u00e1s importante utilizado en la producci\u00f3n actual de al\u00famina, y su producci\u00f3n representa alrededor de 95% del total de la producci\u00f3n mundial de al\u00famina.<\/p>\n

La al\u00famina electroliza el aluminio met\u00e1lico bajo la acci\u00f3n de una corriente intensa, y este proceso se denomina aluminio electrol\u00edtico.<\/p>\n

\"\"<\/p>\n

En lo que respecta a la metalurgia, el uso de placas filtrantes de espuma cer\u00e1mica<\/a> La eliminaci\u00f3n de impurezas extra\u00f1as del aluminio fundido, como la escoria y las inclusiones, es uno de los m\u00e9todos m\u00e1s eficaces de purificaci\u00f3n del metal fundido.<\/p>\n

El filtro de cer\u00e1mica moldeada est\u00e1 compuesto por numerosos microporos uniformes. Cuando el aluminio l\u00edquido atraviesa estos microporos, las part\u00edculas en suspensi\u00f3n quedan retenidas en la superficie del medio filtrante, y el fluido pasa a trav\u00e9s de los canales de los microporos, lo que produce diversos efectos f\u00edsicos que permiten lograr la filtraci\u00f3n mec\u00e1nica, la purificaci\u00f3n, la difusi\u00f3n y la fluidizaci\u00f3n.<\/p>\n

La rejilla met\u00e1lica y el filtro de tela de fibra solo pueden eliminar las inclusiones de mayor tama\u00f1o presentes en la masa fundida de aleaci\u00f3n de aluminio, pero no pueden eliminar las inclusiones por debajo del nivel de la micra. Adem\u00e1s, la rejilla met\u00e1lica contamina la aleaci\u00f3n de aluminio. La placa filtrante de espuma cer\u00e1mica permite filtrar las inclusiones finas y mejora significativamente las propiedades mec\u00e1nicas y la calidad est\u00e9tica de las piezas fundidas.<\/p>","protected":false},"excerpt":{"rendered":"
