La presencia de escoria provoca ara\u00f1azos, obstrucciones y desgarros en el perfil de la matriz de extrusi\u00f3n. Dado que la barra de aleaci\u00f3n 6063 se funde directamente con aluminio l\u00edquido electrol\u00edtico, la cantidad de escoria contenida en el aluminio l\u00edquido es elevada, lo que hace que el proceso de refinado del aluminio sea especialmente importante. En el refinado, tomamos principalmente las siguientes medidas:<\/p>\n

    \n
  1. Elige productos de alta calidad agentes refinadores<\/a>. Algunos agentes de refinado tienen un bajo contenido en Na\u2083AlF\u2086 (crioita), y su eficacia para eliminar escorias y gases es muy escasa.<\/li>\n
  2. Pasar del refinado primario al refinado secundario de refuerzo. La primera dosis es de 3-4 kg por tonelada de aluminio, y en el segundo refinado intensificado se utilizan 2-3 kg del ba\u00f1o fundido por tonelada de aluminio, sin dejar zonas sin tratar, mezclando y refinando a fondo.<\/li>\n
  3. La campana de vidrio se introduce en el ba\u00f1o de metal fundido para su refinado mediante inyecci\u00f3n de nitr\u00f3geno en polvo.<\/li>\n
  4. Para evitar la reoxidaci\u00f3n del aluminio fundido, se esparce una capa de agente de recubrimiento en el ba\u00f1o de fundici\u00f3n tras el refinado, y se procede a la colada tras un reposo de 20 minutos.<\/li>\n
  5. Filtrar por filtro de espuma cer\u00e1mica<\/a> durante la colada. Deja que el metal fundido fluya a trav\u00e9s de \u00e9l y realiza una desescoriado secundario.<\/li>\n<\/ol>\n

    AdTech resuelve espec\u00edficamente el problema de las inclusiones de escoria en el aluminio fundido. AdTech ofrece equipos de desgasificaci\u00f3n en l\u00ednea<\/a>, placas filtrantes de espuma cer\u00e1mica, fundente para la fundici\u00f3n de aluminio, canales de colada y otros materiales refractarios.<\/p>\n

    \"Refinado<\/p>\n

    La c\u00e1mara de desgasificaci\u00f3n se utiliza principalmente para eliminar el hidr\u00f3geno (H) y las escorias del aluminio fundido. Funciona seg\u00fan el principio de la flotaci\u00f3n por aire. El rotor aspira gas inerte o una mezcla de cloro y gas inerte hacia el aluminio fundido y lo pulveriza en peque\u00f1as burbujas dispersas. Las burbujas ascienden a la superficie del aluminio fundido y, al mismo tiempo, llevan a cabo los siguientes pasos: el H es absorbido por las burbujas y eliminado, y se eliminan el cloruro y la escoria.<\/p>\n

    Sistema de filtrado CFF<\/a> Se utiliza para filtrar y purificar el aluminio fundido, en combinaci\u00f3n con el filtro de espuma cer\u00e1mica. Permite filtrar las inclusiones y las part\u00edculas min\u00fasculas presentes en el aluminio fundido. Es especialmente adecuado para la fundici\u00f3n de aluminio de alta pureza y aleaciones de aluminio de alta precisi\u00f3n. Presenta las siguientes ventajas: resistencia t\u00e9rmica, resistencia a la oxidaci\u00f3n, resistencia a la corrosi\u00f3n, calentamiento r\u00e1pido, larga vida \u00fatil y resistencia a los \u00e1cidos.<\/p>","protected":false},"excerpt":{"rendered":"
