Filtro cer\u00e1mico poroso Zro2<\/strong><\/p>\n

La filtraci\u00f3n de los fundidos se ha convertido hoy en d\u00eda en una parte fundamental del proceso tecnol\u00f3gico de fundici\u00f3n y colada de aleaciones de aluminio en todas las empresas. Se utilizan filtros de malla, granulares y de cer\u00e1mica porosa.<\/p>\n

Los filtros est\u00e1n fabricados con fibra de vidrio o malla met\u00e1lica, con un tama\u00f1o de malla que oscila entre 0,5 \u00d7 0,5 mm y 1,5 \u00d7 1,5 mm.
\nEl filtro cer\u00e1mico poroso Zro2 retiene aquellas part\u00edculas que son m\u00e1s grandes que los poros de la malla.
\nSu uso permite reducir entre 1,5 y 2 veces el contenido de inclusiones grandes y pel\u00edculas. Sin embargo, no influyen en el contenido de inclusiones finas ni de hidr\u00f3geno.
\nNormalmente, los filtros cer\u00e1micos porosos Zro2 se instalan en el conector de forma situado debajo del tubo ascendente.<\/p>\n

Los filtros granulares son mucho m\u00e1s eficaces. Se obtienen a partir de migas de arcilla refractaria, magnesita, alunda, s\u00edlice, aleaciones de sales de cloruro y fluoruro (fundentes de refinado) y otros materiales.
\nLa eficacia con la que se eliminan las inclusiones no met\u00e1licas en suspensi\u00f3n depende de la naturaleza del material filtrante, as\u00ed como del di\u00e1metro y la longitud de los canales intergranulares.
\nLa limpieza se debe a procesos mec\u00e1nicos y adhesivos.
\nLos filtros cer\u00e1micos porosos Zro2, fabricados a partir de fundentes triturados y refundidos, se denominan \u00abactivos\u00bb.
\nGracias a los procesos de adhesi\u00f3n, permiten separar hasta 40% de suspensiones finamente dispersas y reducir el contenido de hidr\u00f3geno en las aleaciones que han sido sometidas a refinado en una proporci\u00f3n de entre 10 y 20%.<\/p>\n

\"Filtro<\/p>\n

Los filtros granulares, as\u00ed como los coladores, se instalan en el recorrido que sigue el metal al verterse en el molde.
\nEl tama\u00f1o medio de los granos del material filtrante oscila entre 4 y 15 mm de di\u00e1metro, y la altura de la capa es de 100 a 150 mm. Cuentan con filtros granulares en el crisol de colada, en el canal de subida o en la cubeta de colada.
\nEl llenado se realiza de tal forma que el filtro quede cubierto por una capa de material fundido de entre 10 y 15 mm.
\nSe recomienda calentar los filtros granulares a una temperatura de entre 700 y 720 \u00b0C.
\nEsto te permite eliminar la humedad adsorbida y evitar que el metal se congele en los conductos estrechos.
\nEl caudal de la masa fundida a trav\u00e9s de los canales intergranulares de los filtros influye de manera significativa en el grado de separaci\u00f3n de las inclusiones y los residuos.
\nA caudales elevados, disminuye la posibilidad de que se produzcan precipitaciones de inclusiones y aumenta la probabilidad de que las part\u00edculas ya sedimentadas sean arrastradas.<\/p>\n

Los filtros de granulado a granel no siempre garantizan la estabilidad del proceso de limpieza de la masa fundida.
\nCon una disposici\u00f3n aleatoria entre los granos de gran tama\u00f1o, pueden formarse canales de gran secci\u00f3n transversal.
\nEstas deficiencias no se dan en los filtros cer\u00e1micos porosos modernos de gran volumen, independientemente de su forma y de la secci\u00f3n transversal de sus canales.
\nEst\u00e1n fabricados con Al\u2082O\u2083, SiO\u2082, ZrO\u2082 y otros materiales.
\nLos filtros cer\u00e1micos pueden suministrarse en forma de bloques grandes o de productos moldeados de cualquier forma, seg\u00fan las necesidades del cliente.<\/p>","protected":false},"excerpt":{"rendered":"
