El m\u00e9todo general actual de purificaci\u00f3n del aluminio fundido es el siguiente: tras salir del horno de fundici\u00f3n, se conectan la caja de desgasificaci\u00f3n y la caja de filtrado mediante el canal de colada, y a continuaci\u00f3n se transfiere el aluminio a la placa de molde para su colada. En este proceso, el canal de colada es largo, y el aluminio fundido genera escoria y gases al pasar por el canal y la placa de moldeo, lo que afecta a la calidad del aluminio fundido.<\/p>\n

El m\u00e9todo de purificaci\u00f3n del aluminio fundido integra un dispositivo de desgasificaci\u00f3n y filtrado para acortar la longitud del canal de flujo<\/a> en la medida de lo posible, con lo que se logra el objetivo de reducir la contaminaci\u00f3n del aluminio fundido. El aluminio fundido entra en el unidad de desgasificaci\u00f3n<\/a> a trav\u00e9s del canal de flujo. Cuando el aluminio fundido llena la caja de desgasificaci\u00f3n hasta una determinada altura, el nitr\u00f3geno entra en el aluminio fundido a trav\u00e9s de los ladrillos de ventilaci\u00f3n y comienza la operaci\u00f3n de desgasificaci\u00f3n y refinado.<\/p>\n

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

Tras la desgasificaci\u00f3n, el contenido de hidr\u00f3geno de la masa fundida puede reducirse considerablemente. Tras la desgasificaci\u00f3n, el aluminio fundido fluye hacia la c\u00e1mara de filtrado situada junto a la c\u00e1mara de desgasificaci\u00f3n. Se coloca la placa filtrante de cer\u00e1mica celular en la caja de filtrado. Bajo la acci\u00f3n de la presi\u00f3n hidrost\u00e1tica, el aluminio atraviesa la placa filtrante y, una vez completada la primera filtraci\u00f3n, entra en el dep\u00f3sito de flujo a trav\u00e9s de la salida de agua. Para evitar el agitado y la formaci\u00f3n de escoria del aluminio fundido en caso de una ca\u00edda pronunciada, no se utiliza el m\u00e9todo de inclinaci\u00f3n excesiva y \u00e1ngulo en esquina desde el canal de vertido hasta el molde, sino que se emplea el m\u00e9todo del canal de vertido, y se perfora el tubo gu\u00eda en el extremo del canal. El aluminio l\u00edquido fluye hacia el canal de colada desde el tubo de alimentaci\u00f3n, y la salida del tubo queda sumergida bajo la superficie del l\u00edquido del canal de colada para evitar la oxidaci\u00f3n y la formaci\u00f3n de escoria. El aluminio fundido se filtra a trav\u00e9s de la placa filtrante por gravedad. En dos etapas Filtraci\u00f3n CFF<\/a> Puede eliminar las impurezas de m\u00e1s de 10 \u03bcm y purificar el aluminio fundido. Con esto, se completa el proceso de desgasificaci\u00f3n y filtrado. Una vez realizados los pasos mencionados anteriormente, se obtiene una barra fundida con un alto grado de purificaci\u00f3n.<\/p>","protected":false},"excerpt":{"rendered":"
