Filtro de espuma cer\u00e1mica para aluminio l\u00edquido<\/strong><\/p>\n

Filtro de espuma cer\u00e1mica para aluminio l\u00edquido, compuesto por 80%, debido a la presencia de Al\u2082O\u2083, MgO y compuestos similares a Al\u2082MgO\u2084 en forma de escamas.
\nFormaci\u00f3n e ingredientes de las inclusiones, material del revestimiento y de la rampa de colada, composici\u00f3n de los gases del horno, tecnolog\u00eda de refinado y colada, y otros aspectos relacionados.
\nLa presencia de una peque\u00f1a cantidad de inclusiones finas puede reducir el grado de cristalinidad de la sobreenfriamiento y favorecer la nucleaci\u00f3n.
\nSin embargo, la presencia excesiva de inclusiones afectar\u00eda negativamente a la calidad de los lingotes o productos, al pl\u00e1stico, a la resistencia a la corrosi\u00f3n, a la oxidaci\u00f3n an\u00f3dica y al aspecto.
\nAl mismo tiempo, la presencia de gases par\u00e1sitos (principalmente hidr\u00f3geno) provocar\u00e1 la aparici\u00f3n de poros, productos sueltos, grietas y otros defectos. Por lo tanto, la limpieza es el proceso clave en la fundici\u00f3n del aluminio.
\nM\u00e9todo habitual de filtrado del aluminio fundido. En el proceso moderno de purificaci\u00f3n del aluminio fundido, el filtrado es uno de los \u00faltimos pasos del proceso de purificaci\u00f3n previo a la colada.
\nAnteriormente, tras el proceso de refinado en horno con fundente, el reposo y la adsorci\u00f3n con y sin medios filtrantes, aunque ya se hab\u00edan eliminado las inclusiones y los gases del 60% al 80%, la masa fundida a\u00fan presentaba inclusiones m\u00e1s finas dispersas (con un di\u00e1metro de grano generalmente inferior a 15 \u03bcm) (incluidas las inclusiones primarias y secundarias procedentes de la rampa de descarga y del contrato de producci\u00f3n intermedia).
\nPara obtener productos de aluminio de alto rendimiento, debemos llevar a cabo la concentraci\u00f3n de esas inclusiones finas y su separaci\u00f3n por adsorci\u00f3n.
\nEn comparaci\u00f3n con otros m\u00e9todos de purificaci\u00f3n, el m\u00e9todo de filtraci\u00f3n, gracias a su bajo consumo energ\u00e9tico, su f\u00e1cil manejo, su alta eficacia de limpieza y su menor generaci\u00f3n de contaminaci\u00f3n secundaria, se ha convertido en el proceso de purificaci\u00f3n final preferido para el aluminio fundido.
\nLos filtros de tela y malla de vidrio se basan principalmente en la separaci\u00f3n mec\u00e1nica de las impurezas mediante su interceptaci\u00f3n; presentan una estructura sencilla y un bajo coste, y son adecuados para filtrar part\u00edculas grandes, pero tienen poca eficacia en la microfiltraci\u00f3n de impurezas. Adem\u00e1s, al tratarse de filtros de baja intensidad t\u00e9rmica, su vida \u00fatil es corta, su rendimiento es inestable y solo se pueden utilizar una vez, por lo que se emplean principalmente para el prefiltrado de la masa fundida.<\/p>\n

Sus ventajas son su alta porosidad, su elevada eficiencia de filtraci\u00f3n, su facilidad de sustituci\u00f3n, su bajo coste y su adaptabilidad; adem\u00e1s, permite aislar mediante filtraci\u00f3n las inclusiones s\u00f3lidas de las inclusiones l\u00edquidas. Sus desventajas son su baja resistencia a altas temperaturas, su corta vida \u00fatil (en su mayor\u00eda de un solo uso) y su capacidad para filtrar solo peque\u00f1as cantidades.<\/p>","protected":false},"excerpt":{"rendered":"
