Normalmente, durante el proceso de solidificaci\u00f3n, a medida que disminuye la solubilidad del hidr\u00f3geno, ya es demasiado tarde para que este se escape de la soluci\u00f3n, y tambi\u00e9n lo es para que las impurezas no met\u00e1licas floten hasta la superficie del l\u00edquido antes de entrar en el cristalizador, lo que provocar\u00e1 la aparici\u00f3n de placas y l\u00e1minas en el posterior proceso de laminaci\u00f3n. Aumentan las manchas blancas y los poros en la superficie del material, y disminuyen sus propiedades mec\u00e1nicas, lo que acaba provocando el desecho del producto. Por lo tanto, el tratamiento de desgasificaci\u00f3n del aluminio es importante.<\/p>\n<h2>Tratamiento de desgasificaci\u00f3n del aluminio<\/h2>\n<p>El principio de funcionamiento del <a href=\"http:\/\/www.alalloycasting.com\/es\/aluminum-degassing\/\">Desgasificaci\u00f3n del aluminio<\/a> El tratamiento consiste en utilizar un gas inerte que no reaccione qu\u00edmicamente con el aluminio l\u00edquido a la temperatura de fusi\u00f3n y que sea insoluble en la masa fundida.<\/p>\n<p>El eje de grafito, que gira a gran velocidad, lo inyecta en el aluminio fundido para formar una gran cantidad de peque\u00f1as burbujas continuas.<\/p>\n<p>Cuando las burbujas de gas inerte ascienden desde el fondo de la c\u00e1mara de fusi\u00f3n, debido a la diferencia de presi\u00f3n, el hidr\u00f3geno presente en la masa fundida seguir\u00e1 difundi\u00e9ndose hacia las burbujas.<\/p>\n<p>Una vez que las burbujas suben a la superficie, el hidr\u00f3geno que contienen se escapa a la atm\u00f3sfera. Durante el proceso de flotaci\u00f3n de las burbujas, cuando estas se encuentran con inclusiones no met\u00e1licas, debido al efecto de la tensi\u00f3n superficial, las inclusiones se adhieren a la superficie de la burbuja y se eliminan a medida que esta asciende.<\/p>\n<p>Al mismo tiempo, el medio filtrante de la cavidad del filtro retendr\u00e1 a\u00fan m\u00e1s las impurezas, de modo que los sedimentos del dep\u00f3sito queden retenidos en el medio filtrante y el aluminio l\u00edquido pueda purificarse por completo.<\/p>\n<p>Las cajas de filtros de placas son equipos imprescindibles para los sistemas de purificaci\u00f3n por filtraci\u00f3n en la colada continua y la colada semicontinua, ya que garantizan una filtraci\u00f3n estable.<\/p>","protected":false},"excerpt":{"rendered":"<p>The hydrogen content and non-metallic impurities of the molten aluminum alloy in the melting and casting workshop will seriously affect the
