Sistema de refinado de aluminio l\u00edquido<\/strong>, en el que el unidad de desgasificaci\u00f3n<\/a> El cuerpo est\u00e1 moldeado y sinterizado de una sola pieza con un material de fundici\u00f3n importado de alta resistencia, que presenta una buena resistencia al choque t\u00e9rmico.
\nLa capa aislante del exterior de la caja est\u00e1 fabricada con nanoboard importado de alta calidad, tablero de fibra ligero y otros materiales, que ofrecen un buen rendimiento aislante.
\nLa cubierta de la caja se fabrica mediante fundici\u00f3n y sinterizaci\u00f3n integrales con materiales de fundici\u00f3n ligeros.
\nEl principio de funcionamiento del unidad de desgasificaci\u00f3n<\/a> consiste en inyectar una determinada cantidad de Ar-Cl\u2082 o N\u2082-Cl\u2082, arg\u00f3n puro o nitr\u00f3geno gaseoso en el fondo del ba\u00f1o de aluminio fundido a trav\u00e9s de un rotor que gira a alta velocidad, y el impulsor lo fragmenta por completo para formar burbujas dispersas, con el fin de que el aluminio l\u00edquido y el gas de arg\u00f3n o nitr\u00f3geno entren en contacto total.
\nSeg\u00fan el principio de la diferencia de presi\u00f3n atmosf\u00e9rica y la adsorci\u00f3n superficial, cuando las burbujas ascienden, se adsorben el hidr\u00f3geno y la escoria oxidada, se forma una capa de espuma en la superficie y el hidr\u00f3geno es expulsado, con lo que se consigue eliminar el hidr\u00f3geno y la escoria.<\/p>\n

Durante el funcionamiento del sistema de refinado de aluminio l\u00edquido<\/strong>, los accionamientos del motor<\/strong> la rotaci\u00f3n del rotor para fragmentar el nitr\u00f3geno o el arg\u00f3n inyectado en el aluminio fundido en un gran n\u00famero de burbujas dispersas y distribuirlas por todo el metal fundido.
\nBurbujas en la masa fundida<\/strong>, aprovechando la diferencia de presi\u00f3n parcial de los gases y el principio de adsorci\u00f3n superficial, absorben hidr\u00f3geno del ba\u00f1o de fusi\u00f3n, adsorben la escoria oxidada y son expulsadas de la superficie del ba\u00f1o de fusi\u00f3n a medida que las burbujas ascienden, lo que permite purificar el ba\u00f1o de fusi\u00f3n.
\nDado que las burbujas son peque\u00f1as y est\u00e1n dispersas<\/strong>, se mezclan uniformemente con el metal fundido en rotaci\u00f3n y, a continuaci\u00f3n, giran en forma de espiral para ascender lentamente. El tiempo de contacto con el metal fundido es prolongado, y no se produce una subida lineal continua que genere un flujo de aire, lo que permite eliminar el hidr\u00f3geno nocivo del aluminio fundido y mejorar significativamente el efecto de purificaci\u00f3n.<\/p>\n

\u00bfPor qu\u00e9 es necesario el sistema de refinado de aluminio l\u00edquido en el proceso de fundici\u00f3n del aluminio?<\/h2>\n

Las fundiciones de aluminio y de aleaciones de aluminio contienen una gran cantidad de hidr\u00f3geno, metal e inclusiones no met\u00e1licas.<\/strong>
\nSi no se logran eliminar a tiempo las sustancias nocivas mencionadas anteriormente antes de la fundici\u00f3n, se producir\u00e1n defectos en la pieza fundida, como poros, inclusiones y falta de compactaci\u00f3n, tanto en el interior como en la superficie de la misma, lo que afectar\u00e1 gravemente a sus propiedades f\u00edsicas, qu\u00edmicas, mec\u00e1nicas y a diversas caracter\u00edsticas relacionadas con el procesamiento posterior, adem\u00e1s de generar una gran cantidad de residuos.<\/strong>
\nNo se produce corrosi\u00f3n en el revestimiento de la cuchara o del horno de crisol. Dado que se utiliza arg\u00f3n o nitr\u00f3geno como medio de refinado, no se contamina el medio ambiente.<\/strong><\/p>\n
