Fundici\u00f3n de filtros cer\u00e1micos en la industria del aluminio de China<\/strong> La industria de transformaci\u00f3n se ha generalizado, y existen dos modalidades principales de aplicaci\u00f3n en la purificaci\u00f3n del fundido de aleaciones de aluminio deformadas.
\n1. En la l\u00ednea de colada semicontinua de aleaci\u00f3n de aluminio, la masa fundida se refina mediante la pulverizaci\u00f3n de fundente en el horno, y la placa cer\u00e1mica de espuma se utiliza para el filtrado fuera del horno.
\nLa placa filtrante de cer\u00e1mica se sustituye cada vez que se realiza una colada. Hoy en d\u00eda, algunas plantas de procesamiento de aluminio incorporan un desaireador en l\u00ednea de tipo canal antes del filtrado para mejorar el efecto de purificaci\u00f3n.
\n2. En la l\u00ednea de colada continua y laminaci\u00f3n, el ciclo de sustituci\u00f3n se determina en funci\u00f3n de la diferencia de presi\u00f3n antes y despu\u00e9s del Fundici\u00f3n de filtros cer\u00e1micos<\/a>.
\nEl tama\u00f1o de la placa filtrante utilizada se determina en funci\u00f3n del caudal por unidad de tiempo del aluminio fundido y de la cantidad total de aluminio fundido.
\nLa elecci\u00f3n de una placa filtrante de cer\u00e1mica porosa con un gran n\u00famero de mallas se basa en los requisitos de pureza del aluminio l\u00edquido final.
\nCuanto mayor sea el nivel de pureza exigido para el aluminio fundido, menor ser\u00e1 el tama\u00f1o de poro seleccionado.<\/p>\n

La purificaci\u00f3n en la fundici\u00f3n mediante filtros cer\u00e1micos es el \u00faltimo proceso de purificaci\u00f3n del aluminio l\u00edquido.<\/strong>
\nAntes de este proceso, se utilizaban t\u00e9cnicas como el refinado por pulverizaci\u00f3n de fundente o el tratamiento de desgasificaci\u00f3n rotativa en l\u00ednea, por lo que las part\u00edculas de hidr\u00f3geno de la fase de impurezas presentes en el aluminio l\u00edquido que no se hab\u00edan eliminado eran m\u00e1s finas y estaban m\u00e1s dispersas.
\nEs especialmente importante saber c\u00f3mo favorecer la acumulaci\u00f3n de fases de impurezas y la adsorci\u00f3n de hidr\u00f3geno en la filtraci\u00f3n con cer\u00e1mica celular.<\/p>\n

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

Con el desarrollo de la ciencia y la tecnolog\u00eda, la producci\u00f3n industrial plantea exigencias cada vez mayores en cuanto a la pureza y la calidad del aluminio y sus aleaciones.
\nEl proceso tradicional de refinado y desgasificaci\u00f3n no permite eliminar las inclusiones no met\u00e1licas peque\u00f1as y en suspensi\u00f3n presentes en el aluminio fundido. Por ello, se han estudiado numerosos m\u00e9todos de purificaci\u00f3n. Seg\u00fan sus diferentes mecanismos y formas, pueden clasificarse en purificaci\u00f3n por adsorci\u00f3n, purificaci\u00f3n f\u00edsica y purificaci\u00f3n por filtraci\u00f3n [1]. La purificaci\u00f3n por filtraci\u00f3n consiste en hacer que el metal fundido fluya a trav\u00e9s de un medio determinado; este medio captura las inclusiones seg\u00fan un mecanismo concreto, purificando as\u00ed el metal. En 1978, Estados Unidos desarroll\u00f3 un nuevo tipo de filtro \u2014el filtro de espuma cer\u00e1mica\u2014, que proporciona un filtrado de alta eficiencia para la producci\u00f3n de piezas de aluminio fundido.<\/p>\n

La fundici\u00f3n de aleaciones de aluminio es una parte importante del proceso de transformaci\u00f3n de estas aleaciones, lo que se refleja en las tecnolog\u00edas de aleaci\u00f3n, purificaci\u00f3n y refinado del proceso de fundici\u00f3n. La eliminaci\u00f3n de inclusiones no met\u00e1licas en la masa fundida de aleaci\u00f3n de aluminio mediante el tratamiento con fundente en el horno y la filtraci\u00f3n a trav\u00e9s de espuma cer\u00e1mica fuera del horno se ha convertido desde hace tiempo en un m\u00e9todo importante para la purificaci\u00f3n del aluminio fundido.<\/p>","protected":false},"excerpt":{"rendered":"
