Los fundentes compuestos para la refinaci\u00f3n del aluminio son una mezcla de sales obtenida mediante la combinaci\u00f3n o fusi\u00f3n de dos o m\u00e1s sales individuales. Se trata del tipo de agente de refinaci\u00f3n m\u00e1s utilizado en la industria del aluminio. Se pueden elegir diferentes agentes de refinado en funci\u00f3n de diversos requisitos, como fundentes compuestos para agentes purificadores, agentes de escoria, agentes de recubrimiento y agentes de eliminaci\u00f3n de magnesio. Ofrecemos fundente granulado y en polvo en dos formatos. En comparaci\u00f3n con el fundente en polvo, los productos granulados no generan polvo y son m\u00e1s eficaces, ya que basta con a\u00f1adir una peque\u00f1a cantidad.<\/p>\n

En las fundiciones de aluminio y aleaciones de aluminio, los fundentes de refinado del aluminio son sustancias capaces de eliminar gases, inclusiones y elementos nocivos de la fundici\u00f3n mediante interacciones f\u00edsicas y qu\u00edmicas. Entre los agentes de refinado de aleaciones de aluminio m\u00e1s utilizados, seg\u00fan sus funciones, se encuentran el agente de recubrimiento, el agente desgasificador y el agente de refinado (tambi\u00e9n conocido como agente purificador compuesto), agente de escoria<\/a> (tambi\u00e9n conocido como separador de escoria y aluminio), agente de limpieza de hornos, agente de eliminaci\u00f3n de magnesio y agente desgasificador.<\/p>\n

Los agentes de refinado a base de sales de cloruro que se utilizan habitualmente suelen caracterizarse por su alta volatilidad, su bajo punto de ebullici\u00f3n y una reacci\u00f3n muy intensa durante el proceso de refinado. Sin embargo, las sales de cloruro son, en general, higrosc\u00f3picas, y el producto final de la reacci\u00f3n, el cloruro de aluminio, presenta un cierto grado de toxicidad y contamina el medio ambiente. Algunas sales de cloruro aumentan el contenido de impurezas met\u00e1licas, por lo que su uso est\u00e1 restringido.<\/p>\n

\"\"<\/p>\n

Los requisitos b\u00e1sicos para los fundentes de refinado de aluminio son:<\/p>\n

\u2460En el rango de temperaturas de trabajo no se produce ninguna reacci\u00f3n qu\u00edmica perjudicial para el aluminio fundido.
\n\u2461 Presenta buenas propiedades de refinado, recubrimiento o escorificaci\u00f3n, o bien ofrece el rendimiento necesario para eliminar las impurezas met\u00e1licas.
\n\u2462El punto de fusi\u00f3n debe ser inferior a la temperatura de fusi\u00f3n y presentar una buena fluidez en estado l\u00edquido; independientemente del tipo de fundente compuesto que se utilice, debe separarse f\u00e1cilmente del aluminio fundido y no adherirse a las paredes del horno ni a las herramientas.
\n\u2463La densidad debe ser inferior a la del aluminio fundido a la temperatura de trabajo.
\n\u2464 S\u00e9calo bien.
\n\u2465Fuentes suficientes, suministro c\u00f3modo y precios bajos.<\/p>","protected":false},"excerpt":{"rendered":"
