La fundici\u00f3n y refinado del aluminio permiten desgasificarlo y eliminar las impurezas, lo que aumenta la pureza de la aleaci\u00f3n de aluminio y mejora sus propiedades mec\u00e1nicas.<\/p>\n

Hay muchos aspectos que hay que tener en cuenta a la hora de a\u00f1adir refinadores. A continuaci\u00f3n se describe el m\u00e9todo de uso espec\u00edfico.<\/p>\n

El hidr\u00f3geno y la escoria de \u00f3xido flotante pueden eliminarse eficazmente a\u00f1adiendo la cantidad adecuada de agente de fundici\u00f3n de aluminio.<\/p>\n

La raz\u00f3n principal es que el agente de refinado se descompone f\u00e1cilmente a altas temperaturas; adem\u00e1s, el gas producido es propenso a sufrir reacciones qu\u00edmicas, y la fuerte capacidad de adsorci\u00f3n de la escoria permite que el hidr\u00f3geno se escape de la masa fundida, por lo que tiene un efecto evidente en la eliminaci\u00f3n de la escoria.<\/p>\n

El uso de agentes refinadores<\/a> Es relativamente sencillo; puedes informarte mejor sobre su uso antes de utilizarlos.<\/p>\n

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

Espolvorear de manera especialmente uniforme sobre la superficie del l\u00edquido, presionar r\u00e1pidamente para que se sumerja en el aluminio l\u00edquido, remover bien hasta que se asiente y, a continuaci\u00f3n, retirar la escoria.<\/p>\n

Adem\u00e1s, durante el proceso de uso se puede aplicar mediante pulverizaci\u00f3n, preferiblemente con inyecci\u00f3n de gas inerte. La cantidad utilizada es de aproximadamente 0,3% en peso de aluminio l\u00edquido. Si la pureza del aluminio l\u00edquido es mayor, consulte a m\u00e1s refinadores.<\/p>\n

El m\u00e9todo de pulverizaci\u00f3n utilizado en la fundici\u00f3n y refinado del aluminio presenta una mayor superficie de contacto con el aluminio l\u00edquido. El refinador en polvo se pulveriza en la soluci\u00f3n a trav\u00e9s de un pulverizador.<\/p>\n

Durante la pulverizaci\u00f3n, se suelen utilizar nitr\u00f3geno y arg\u00f3n como gases portadores, lo que da lugar a la formaci\u00f3n de un gran n\u00famero de burbujas dispersas en la soluci\u00f3n de aleaci\u00f3n de aluminio. Durante el proceso de flotaci\u00f3n de las burbujas, el aluminio l\u00edquido entra en contacto completo con ellas, lo que permite la eliminaci\u00f3n oportuna del gas y de las inclusiones del aluminio l\u00edquido.<\/p>\n

El agente refinador debe a\u00f1adirse en funci\u00f3n del peso del aluminio l\u00edquido, ya que una cantidad excesiva o insuficiente afectar\u00e1 al rendimiento de la aleaci\u00f3n de aluminio, por lo que debe calcularse antes de a\u00f1adirlo.<\/p>\n

Durante el funcionamiento del agente de refinado, el operario debe regular libremente el flujo de refinado mediante el bar\u00f3metro y el dosificador de polvo, con el fin de controlar el grado de agitaci\u00f3n del aluminio l\u00edquido y reducir la contaminaci\u00f3n secundaria.<\/p>\n

La cantidad de agente refinador es de 0,10-0,201 TP3T, y debe seleccionarse en funci\u00f3n de las circunstancias concretas durante su uso.<\/p>","protected":false},"excerpt":{"rendered":"
