El filtro de fundici\u00f3n de aluminio puede eliminar eficazmente las inclusiones presentes en el aluminio fundido y mejorar significativamente la calidad de los productos de aluminio. Debido a la afinidad del aluminio por el ox\u00edgeno, el \u00f3xido es la inclusi\u00f3n m\u00e1s habitual en todas las aleaciones de aluminio fundidas. En la industria moderna de la fundici\u00f3n de aluminio, durante el proceso de fabricaci\u00f3n de productos de aluminio, el filtro de espuma cer\u00e1mica para fundici\u00f3n puede eliminar eficazmente las impurezas de al\u00famina presentes en la masa fundida de aluminio y mejorar la calidad de los productos de aluminio.<\/p>\n

Si no se elimina la composici\u00f3n qu\u00edmica de las inclusiones no met\u00e1licas formadas en el aluminio fundido \u2014cuya composici\u00f3n qu\u00edmica es muy estable\u2014, se producen f\u00e1cilmente grietas en la pieza fundida tras la solidificaci\u00f3n. La presencia de inclusiones no met\u00e1licas hace que las propiedades mec\u00e1nicas de las piezas de fundici\u00f3n sean dif\u00edciles de predecir. Se considera que la influencia de las inclusiones de \u00f3xido en las propiedades de tracci\u00f3n de la aleaci\u00f3n de aluminio es la principal causa del deterioro de las propiedades mec\u00e1nicas de dicha aleaci\u00f3n. Por lo tanto, es muy necesario que las empresas del sector del aluminio utilicen filtros de fundici\u00f3n Alu.<\/p>\n

El filtro de espuma cer\u00e1mica (CFF) se utiliza ampliamente en la producci\u00f3n de las grandes empresas de transformaci\u00f3n del aluminio de Rusia, Oriente Medio y el Sudeste Asi\u00e1tico. Durante su uso, no solo deben eliminarse las inclusiones del aluminio fundido, sino que tambi\u00e9n debe evitarse la obstrucci\u00f3n del filtro cer\u00e1mico y debe mejorarse la vida \u00fatil del CFF.<\/p>\n

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

Principio de filtraci\u00f3n del filtro para fundici\u00f3n de aluminio<\/h2>\n

Fundici\u00f3n de filtros cer\u00e1micos<\/a> Es un nuevo filtro cer\u00e1mico poroso fabricado a partir de una esponja industrial como soporte, relleno de cer\u00e1mica resistente al calor y posteriormente sinterizado. Cuando la placa filtrante cer\u00e1mica filtra el aluminio, este fluye a trav\u00e9s de los orificios sinuosos del filtro cer\u00e1mico. Las impurezas no met\u00e1licas y la pel\u00edcula de \u00f3xido presentes en la soluci\u00f3n de aluminio se ven afectadas por la presi\u00f3n axial, la fricci\u00f3n y la adsorci\u00f3n superficial del aluminio l\u00edquido. La acci\u00f3n combinada de estos factores hace que la escoria quede atrapada en la superficie interior de los orificios y en los huecos del filtro cer\u00e1mico, lo que provoca la separaci\u00f3n entre la escoria y el aluminio l\u00edquido.<\/p>\n

Tras un periodo de filtraci\u00f3n, la escoria que queda en el filtro de fundici\u00f3n tambi\u00e9n participa en la adsorci\u00f3n de la escoria, lo que contribuye al proceso de filtraci\u00f3n. Dado que la escoria adsorbida en la placa filtrante cer\u00e1mica tiene las mismas propiedades que el aluminio l\u00edquido, su relaci\u00f3n de superficie es mucho mayor que la de la placa filtrante cer\u00e1mica y su actividad superficial es mucho mayor que la del aluminio. Por lo tanto, la capacidad de adsorci\u00f3n y captura de escoria en la soluci\u00f3n de aluminio de la placa filtrante cer\u00e1mica es mucho mayor que la de la placa filtrante cer\u00e1mica.<\/p>\n

Por este motivo, la placa filtrante cer\u00e1mica puede filtrar part\u00edculas muchas veces m\u00e1s peque\u00f1as que sus propios poros. Durante el proceso de filtraci\u00f3n, la escoria adsorbida en la placa filtrante cer\u00e1mica va aumentando gradualmente tras adsorber la escoria presente en el aluminio l\u00edquido. Bajo la agitaci\u00f3n y el desgaste provocados por el flujo del l\u00edquido, la escoria de resistencia extremadamente baja puede romperse o desprenderse de la placa filtrante cer\u00e1mica. Durante la ca\u00edda de la escoria, si la placa filtrante de cer\u00e1mica es gruesa o presenta orificios, esta puede quedar interceptada o volver a ser adsorbida.<\/p>","protected":false},"excerpt":{"rendered":"
