Espuma filtrante cer\u00e1mica<\/strong> Puede eliminar eficazmente diversas inclusiones presentes en el aluminio fundido con una precisi\u00f3n del orden de los micr\u00f3metros, de modo que el aluminio fundido adquiera un flujo laminar uniforme, lo que facilita el punzonado.
\nEstas impurezas suelen provocar la formaci\u00f3n de burbujas e inclusiones en la plancha, lo que afecta gravemente a la pureza del metal fundido y, por consiguiente, 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

Hoy en d\u00eda, existen muchas formas de eliminar estas sustancias nocivas y purificar el aluminio fundido.<\/strong>
\nSeg\u00fan los distintos m\u00e9todos, estos pueden clasificarse en dos categor\u00edas: el procesamiento en horno y el procesamiento continuo fuera del horno (es decir, el procesamiento en l\u00ednea).
\nSeg\u00fan su funci\u00f3n, se puede dividir en dos tipos: principalmente desgasificaci\u00f3n o desescoria. El fabricante de filtros cer\u00e1micos para fundici\u00f3n (www.adtechamm.com) ha presentado un m\u00e9todo de filtraci\u00f3n continua del aluminio fundido mediante placas filtrantes de cer\u00e1mica celular. En el tratamiento continuo externo, la principal operaci\u00f3n de purificaci\u00f3n consiste en eliminar la escoria.<\/p>\n

La espuma filtrante cer\u00e1mica presenta una estructura de malla de cierta resistencia<\/strong>, que puede soportar la diferencia de presi\u00f3n de la superficie del metal l\u00edquido y la influencia del flujo del metal, pero es fr\u00e1gil y quebradizo. Gracias a la estructura precisa de este material, a su calidad uniforme y a su gran superficie, el efecto de filtrado es excelente.<\/p>\n

\"Espuma<\/p>\n

Filtro de mamposter\u00eda de 30 ppi y 40 ppi<\/strong> Normalmente se utiliza espuma de poliuretano como soporte, que se sumerge en una pasta cer\u00e1mica compuesta por polvo fino (como un aditivo de sinterizaci\u00f3n para \u00e1ridos refractarios, aglutinante y agua), y a continuaci\u00f3n se escurre el exceso de pasta. El material cer\u00e1mico que rodea la fibra de espuma se seca, se cuece y se sinteriza a alta temperatura, y finalmente se obtiene el producto cer\u00e1mico de espuma.
\nDado que la temperatura de fundici\u00f3n de la aleaci\u00f3n var\u00eda, para la fundici\u00f3n se debe elegir un filtro cer\u00e1mico de espuma fabricado con material refractario.<\/p>\n

Para resolver este problema, se inserta en el sistema de colada un filtro sencillo, fabricado con malla met\u00e1lica, chapa de acero perforada, etc., con el fin de eliminar las impurezas desde el principio.
\nAl filtro interno con estructura bidimensional, como las fibras de silicato en forma de aguja y las fibras de nitruro de boro.
\nHoy en d\u00eda, los filtros de espuma cer\u00e1mica utilizan el tama\u00f1o de los poros para interceptar mec\u00e1nicamente las part\u00edculas grandes de \u00f3xido mixto, y las capas de filtro para filtrar las part\u00edculas peque\u00f1as de \u00f3xido mixto.
\nAdem\u00e1s, cuenta con funciones de adsorci\u00f3n y rectificaci\u00f3n. La l\u00ednea de producci\u00f3n que utiliza filtros cer\u00e1micos de espuma aumenta considerablemente el rendimiento de las piezas fundidas.<\/p>\n
