Aunque el aluminio fundido se somete a una serie de tratamientos de purificaci\u00f3n en el horno, el grado de purificaci\u00f3n es limitado y, tras el refinado, sigue quedando una cierta cantidad de gas e inclusiones en la masa fundida. Para producir barras redondas de aluminio de alta calidad, la masa fundida de aluminio debe purificarse al m\u00e1ximo. Por este motivo, un Dispositivo en l\u00ednea para la purificaci\u00f3n de aluminio fundido<\/a>\u00a0Se instala entre el horno de fundici\u00f3n y la cuchara de la l\u00ednea de producci\u00f3n, e incluye filtraci\u00f3n y refinado continuo de gases.<\/p>\n

Purificaci\u00f3n en l\u00ednea del aluminio fundido<\/strong><\/p>\n

El gas continuo dispositivo de desgasificaci\u00f3n<\/a> utiliza N\u2082 de alta pureza para girar y pulverizarlo en el aluminio fundido a trav\u00e9s de un rotor de grafito. El aluminio fundido entra por la parte superior de la caja de desgasificaci\u00f3n y desciende en espiral bajo la acci\u00f3n de agitaci\u00f3n del rotor de grafito giratorio. El N\u2082 pulverizado desde el rotor de grafito se fragmenta en finas burbujas bajo la fuerza de fricci\u00f3n de la boquilla y del aluminio l\u00edquido, y se dispersa uniformemente en el aluminio fundido. Las finas burbujas se mezclan completamente con el aluminio fundido aguas abajo durante el proceso de ascenso para extraer el H\u2082 y las inclusiones, y purificar el fundido. La temperatura de desgasificaci\u00f3n en l\u00ednea del aluminio fundido debe situarse entre 720 y 730 \u2103.<\/p>\n

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

El dispositivo de filtro de placas<\/a> Se compone principalmente de una caja filtrante CFF y una placa filtrante de espuma cer\u00e1mica. La placa filtrante se sumerge y se coloca en posici\u00f3n horizontal. El revestimiento interior de la caja filtrante est\u00e1 fabricado con silicio fundido sinterizado de alta densidad, y se le ha a\u00f1adido un material que impide la infiltraci\u00f3n de aluminio para mejorar la vida \u00fatil de la caja filtrante. Al mismo tiempo, presenta un bajo coeficiente de expansi\u00f3n t\u00e9rmica y una mayor resistencia al choque t\u00e9rmico. La funci\u00f3n principal de la placa filtrante es absorber e interceptar las inclusiones de gran tama\u00f1o presentes en la masa fundida, as\u00ed como las inclusiones finas que se encuentran en suspensi\u00f3n debido al gas adsorbido. La placa filtrante de espuma cer\u00e1mica evita que las impurezas entren en la cuchara de colada.<\/p>","protected":false},"excerpt":{"rendered":"
