El proceso de desgasificaci\u00f3n del aluminio fundido consiste en introducir nitr\u00f3geno en la aleaci\u00f3n de aluminio fundida para que sea comprimido por el rotor giratorio de nitruro de silicio, lo que genera un gran n\u00famero de burbujas de difusi\u00f3n, de modo que el l\u00edquido de la aleaci\u00f3n de aluminio y el nitr\u00f3geno entren en contacto completo dentro del dep\u00f3sito de procesamiento.<\/p>\n

Seg\u00fan el principio de la diferencia de presi\u00f3n y la adsorci\u00f3n superficial, las burbujas absorben el hidr\u00f3geno del metal fundido y adsorben la escoria oxidada. La escoria se forma en la superficie del metal fundido. El metal fundido de aleaci\u00f3n de aluminio fluye desde la salida del dispositivo de desgasificaci\u00f3n (situado en la parte inferior del crisol) hasta la m\u00e1quina de colada. El metal fundido de aleaci\u00f3n de aluminio entra continuamente en el dispositivo de desgasificaci\u00f3n, y el nitr\u00f3geno se inyecta de forma continua. Mediante el proceso de desgasificaci\u00f3n, se logra el objetivo de purificar el metal fundido de aleaci\u00f3n de aluminio.<\/p>\n

La aleaci\u00f3n de aluminio es el material estructural de metal no ferroso m\u00e1s utilizado en la industria. Se emplea ampliamente en los sectores de la aviaci\u00f3n, el sector aeroespacial, la automoci\u00f3n, la fabricaci\u00f3n de maquinaria, la construcci\u00f3n naval, la industria qu\u00edmica y otros sectores. Con el r\u00e1pido desarrollo de la econom\u00eda industrial, la demanda de aleaci\u00f3n de aluminio sigue aumentando. El hidr\u00f3geno se disuelve en el material fundido, se difunde hacia las burbujas ascendentes de gas fundido y es transportado hasta la superficie del material fundido. El gas y las inclusiones afectan al producto de aluminio. El proceso de desgasificaci\u00f3n del aluminio fundido es esencial para eliminar el hidr\u00f3geno disuelto y los contenidos no met\u00e1licos del metal fundido antes de la fundici\u00f3n, con el fin de lograr la mejor calidad.<\/p>\n

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

Estructura principal de la unidad de desgasificaci\u00f3n de aluminio fundido<\/h2>\n

Mecanismo de elevaci\u00f3n hidr\u00e1ulico<\/strong><\/p>\n

Para garantizar su posicionamiento preciso, el unidad de desgasificaci\u00f3n de aluminio fundido<\/a> Cuenta con un dispositivo de elevaci\u00f3n hidr\u00e1ulico que se utiliza para controlar el movimiento vertical del rotor de nitruro de silicio y el sistema de calentamiento con varillas de carburo de silicio en forma de U, que puede girar 90\u00b0 en horizontal. El sistema hidr\u00e1ulico ofrece una precisi\u00f3n de posicionamiento relativamente estable.<\/p>\n

Sistema de calefacci\u00f3n<\/strong><\/p>\n

El sistema de calentamiento utiliza un calentador el\u00e9ctrico, y la varilla de carburo de silicio en forma de U recubre el tubo protector cil\u00edndrico de carburo de silicio o nitruro de silicio. En el interior del tubo hay un termopar para medir la temperatura, lo que permite controlar autom\u00e1ticamente la temperatura, y la potencia se puede ajustar libremente en un rango de entre 2 kW y 26 kW.<\/p>\n

El sistema de control de temperatura utiliza una unidad de potencia integrada m\u00e1s avanzada para lograr un control totalmente autom\u00e1tico y evitar as\u00ed los molestos saltos de temperatura que se producen al encender y apagar el calefactor.
\nLos calentadores de varilla de carburo de silicio en forma de U suelen verse afectados por la corriente principal durante los procesos frecuentes de encendido y apagado.<\/p>\n

El calentador de la etapa sin acumulador se desgasta f\u00e1cilmente y tiene una vida \u00fatil corta.<\/p>","protected":false},"excerpt":{"rendered":"
