El filtro de espuma cer\u00e1mica para fundici\u00f3n de metales est\u00e1 dise\u00f1ado para la fundici\u00f3n en molde. Gracias al mecanismo de formaci\u00f3n de la \u201ctorta de filtraci\u00f3n\u201d en el lado de entrada del filtro y a la filtraci\u00f3n en profundidad dentro de la matriz cer\u00e1mica, estos filtros de espuma cer\u00e1mica constituyen un instrumento eficaz para alcanzar la pureza metal\u00fargica del metal fundido durante el proceso de fundici\u00f3n. Adem\u00e1s, los filtros facilitan el llenado del molde, evitando as\u00ed la aparici\u00f3n de defectos indeseables en la pieza fundida.<\/p>\n

Las propiedades de los filtros de espuma cer\u00e1mica para fundici\u00f3n de metales vienen determinadas por la estructura tridimensional abierta de la matriz cer\u00e1mica, creada por un sistema de celdas interconectadas entre s\u00ed. Se caracterizan por una excelente conductividad t\u00e9rmica, estabilidad y resistencia a los cambios bruscos de temperatura.<\/p>\n

El filtro de espuma cer\u00e1mica para fundici\u00f3n de metales se utiliza principalmente en el proceso de purificaci\u00f3n del aluminio y las aleaciones de aluminio. A medida que aumenten y se exijan requisitos cada vez m\u00e1s exigentes en cuanto a la calidad de los productos de aluminio, la aplicaci\u00f3n de los filtros de espuma cer\u00e1mica de al\u00famina ser\u00e1 cada vez m\u00e1s amplia.<\/p>\n

\"Laminado<\/p>\n

Filtraci\u00f3n con filtros de espuma cer\u00e1mica<\/a> puede mejorar la calidad de las piezas de fundici\u00f3n de aluminio de alta calidad.<\/p>\n

La presencia de inclusiones no met\u00e1licas es perjudicial para la producci\u00f3n de piezas de fundici\u00f3n de primera calidad. Las elevadas propiedades mec\u00e1nicas que se pueden alcanzar son un aspecto clave que se pierde f\u00e1cilmente en presencia de inclusiones y capas de \u00f3xido. Las propiedades mec\u00e1nicas de las aleaciones de aluminio de alta resistencia son muy sensibles a las muescas o imperfecciones en la pieza de fundici\u00f3n. La filtraci\u00f3n reduce eficazmente los niveles de inclusiones y los consiguientes efectos de muesca causados por estas. Las t\u00e9cnicas convencionales para intentar eliminar las inclusiones son ineficaces, y el uso de tamices met\u00e1licos o de fibra no es suficiente para mantener el metal realmente libre de elementos no met\u00e1licos nocivos.<\/p>\n

Las piezas fundidas de primera calidad suelen tener unos requisitos m\u00e1s estrictos en cuanto a la aceptabilidad de los defectos superficiales que se detectan mediante la inspecci\u00f3n por penetraci\u00f3n de tinte. Las investigaciones han demostrado que el nivel de dichos defectos se reduce cuando se utiliza la filtraci\u00f3n con espuma cer\u00e1mica.<\/p>\n

Otra ventaja que se obtiene con el uso de filtros de espuma cer\u00e1mica es la reducci\u00f3n de los defectos detectables mediante rayos X en materiales no met\u00e1licos. La presencia de defectos detectables mediante rayos X en estas circunstancias suele ser motivo de rechazo de piezas de fundici\u00f3n de gran valor. La ventaja m\u00e1s significativa es la reducci\u00f3n de los defectos visibles en aquellas zonas consideradas \u201cestructuralmente cr\u00edticas\u201d.\u201d<\/p>","protected":false},"excerpt":{"rendered":"
