Con el desarrollo de la ciencia y la tecnolog\u00eda, los sectores de la automoci\u00f3n, la construcci\u00f3n naval, la aviaci\u00f3n, el sector aeroespacial y otras industrias manufactureras plantean requisitos de calidad cada vez m\u00e1s exigentes para las piezas fundidas de aleaci\u00f3n de aluminio. Adem\u00e1s de garantizar la composici\u00f3n qu\u00edmica, las propiedades mec\u00e1nicas y la precisi\u00f3n dimensional, las piezas de fundici\u00f3n no pueden presentar porosidad ni contracci\u00f3n, ni defectos como poros. La fundici\u00f3n de la aleaci\u00f3n de aluminio es un proceso muy importante en la fabricaci\u00f3n de piezas de fundici\u00f3n. A\u00f1os de experiencia en producci\u00f3n han demostrado que, si el proceso de refinado con fundentes no se controla estrictamente, las piezas de fundici\u00f3n son propensas a presentar defectos como poros, inclusiones de escoria oxidada y contracci\u00f3n, lo que afecta directamente a la calidad de las mismas. Por lo tanto, para obtener piezas de fundici\u00f3n de aleaci\u00f3n de aluminio de alta calidad, es imprescindible controlar estrictamente el proceso de fundici\u00f3n.<\/p>\n

El objetivo del proceso de refinado con fundentes de aluminio es reducir la complejidad de la operaci\u00f3n, mejorar el efecto de refinado de la masa fundida de aleaci\u00f3n de aluminio, aumentar la tasa de aprovechamiento del agente de refinado y lograr un tratamiento de refinado previo al horno estable de la masa fundida de aleaci\u00f3n de aluminio.<\/p>\n

\"Proceso<\/p>\n

Proceso de refinado con fundentes<\/h2>\n

El objetivo principal del refinado de aleaciones de aluminio es eliminar los gases y las inclusiones no met\u00e1licas del ba\u00f1o de fusi\u00f3n, as\u00ed como uniformar la composici\u00f3n de la aleaci\u00f3n. El refinado es un proceso de suma importancia en la fundici\u00f3n. Es fundamental seleccionar correctamente el agente de refinado y controlar la cantidad que se a\u00f1ade. AdTech fundente granular<\/a> Se prepara mezclando diversas sales inorg\u00e1nicas en una proporci\u00f3n determinada tras un tratamiento de secado. Se utiliza principalmente para eliminar el hidr\u00f3geno y la escoria oxidada flotante del aluminio fundido. Por lo general, se debe a\u00f1adir una cantidad equivalente a entre 0,5% y 0,7% de la masa de la aleaci\u00f3n. Controle la temperatura de refinado, que suele mantenerse entre 700 y 7200C. Durante el proceso de refinado, utilice una campana de vidrio para introducir el agente de refinado por lotes hasta unos 2\/3 por debajo de la superficie del metal fundido, y g\u00edrela uniformemente y lentamente en el sentido de las agujas del reloj. La velocidad debe ser lenta y el movimiento estable para evitar una agitaci\u00f3n excesiva del metal fundido, con el fin de impedir que aumente el contenido de hidr\u00f3geno y se produzcan inclusiones.<\/p>","protected":false},"excerpt":{"rendered":"
