cer\u00e1mica celular<\/a>.<\/p>\nEl tubo cer\u00e1mico microporoso de corind\u00f3n puede filtrar las inclusiones de \u00f3xido de varios micras. La ventaja es que tiene un mayor efecto de eliminaci\u00f3n de escoria, pero la desventaja es que su eficiencia es baja.<\/p>\n
La malla de fibra de vidrio presenta una gran adaptabilidad, un funcionamiento sencillo y un bajo coste. Sin embargo, debido a su reducida superficie de apertura, es f\u00e1cil que se obstruya el sistema de colada y la filtraci\u00f3n resulte inestable. Durante su uso, la malla de fibra de vidrio debe sustituirse con frecuencia y resulta dif\u00edcil eliminar las inclusiones de peque\u00f1o tama\u00f1o. El tama\u00f1o de los orificios de la malla de fibra de vidrio es de 1,2 mm \u00d7 1,5 mm, el n\u00famero de orificios por cent\u00edmetro cuadrado es de 30 y el caudal de filtraci\u00f3n es de unos 20 kg\/min.<\/p>\n

Los filtros de espuma cer\u00e1mica para aluminio fundido presentan una alta porosidad, una amplia superficie de adsorci\u00f3n y un funcionamiento sencillo. El filtro de espuma cer\u00e1mica ofrece el mejor efecto de filtrado para las inclusiones oxidadas de m\u00e1s de 10 \u00b5m, pero resulta dif\u00edcil eliminar las inclusiones oxidadas de tama\u00f1o min\u00fasculo. Para obtener aluminio fundido de alta calidad, cuanto menor sea el tama\u00f1o de los poros de la placa filtrante, mejor. En la pr\u00e1ctica, el m\u00e9todo de filtraci\u00f3n con espuma cer\u00e1mica (CFF) suele combinarse con el m\u00e9todo de soplado. Dado que la espuma cer\u00e1mica es fr\u00e1gil, se da\u00f1a con facilidad, no se puede reutilizar y sus poros son relativamente rectos, la eficacia en la eliminaci\u00f3n de inclusiones es baja.<\/p>\n
Las pruebas han demostrado que el uso de un flujo de purificaci\u00f3n de alta eficiencia + Filtraci\u00f3n CFF<\/a> El proceso de purificaci\u00f3n del aluminio fundido permite reducir el contenido de impurezas y la tasa de poros del aluminio puro de los grados 70% a 82% y de 60% a 88%, respectivamente. Tras la desgasificaci\u00f3n en l\u00ednea, se puede mejorar a\u00fan m\u00e1s el rendimiento del aluminio. La clave de la filtraci\u00f3n y purificaci\u00f3n con fundente reside en completar los tres procesos de fusi\u00f3n, desgasificaci\u00f3n y eliminaci\u00f3n de impurezas del aluminio de una sola vez durante el proceso de fundici\u00f3n, lo que puede reducir significativamente los defectos causados por las inclusiones en el aluminio.<\/p>","protected":false},"excerpt":{"rendered":"The ceramic foam molten Alu filters can effectively filter out the inclusions in the aluminum melt and the hydrogen adsorbed on the surface of the…<\/p>","protected":false},"author":1,"featured_media":9997,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20],"tags":[4682,12391],"class_list":["post-9996","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-ceramic-foam-filter","tag-ceramic-foam-filter-for-casting","tag-molten-alu-filters"],"yoast_head":"\n
