La tecnolog\u00eda de tratamiento de purificaci\u00f3n del aluminio fundido es el primer proceso clave que determina la aplicaci\u00f3n de los materiales de aleaci\u00f3n de aluminio. Determina si los materiales de aleaci\u00f3n de aluminio presentan defectos metal\u00fargicos y si son capaces de transmitir sus propiedades de alto rendimiento, y es determinante para su aplicaci\u00f3n y desarrollo en diversos campos.<\/p>\n

El proceso de purificaci\u00f3n de la aleaci\u00f3n de aluminio fundida de la empresa se lleva a cabo principalmente en un horno refinado por flujo<\/a> y los procesos de eliminaci\u00f3n est\u00e1tica de escorias. La eliminaci\u00f3n est\u00e1tica de escorias se basa en la diferencia de densidad entre el \u00f3xido no met\u00e1lico y el propio l\u00edquido de la aleaci\u00f3n. En un periodo de tiempo determinado, el \u00f3xido no met\u00e1lico y el l\u00edquido de la aleaci\u00f3n se separan para lograr la purificaci\u00f3n del aluminio fundido. El objetivo de este art\u00edculo es determinar, mediante experimentos, el tiempo de reposo \u00f3ptimo del aluminio fundido.<\/p>\n

El horno de ensayo es un horno est\u00e1tico de aleaci\u00f3n de aluminio de 20 toneladas. El objetivo del horno est\u00e1tico es eliminar las escorias y, mediante un proceso de estabilizaci\u00f3n y ajuste fino, optimizar la composici\u00f3n de la mezcla de aluminio fundido en el horno de fundici\u00f3n y en el horno de chatarra de aluminio, purificando as\u00ed el aluminio fundido y proporcionando aluminio fundido de alta calidad para la siguiente etapa del proceso.<\/p>\n

El aluminio fundido del horno de fundici\u00f3n y del horno de chatarra de aluminio entra en el horno est\u00e1tico a trav\u00e9s del canal de colada<\/a> Seg\u00fan la proporci\u00f3n, se eleva la temperatura. Cuando la temperatura alcanza los 740 \u2103 o m\u00e1s, se a\u00f1aden 20 kg de agente limpiador de escoria al pulverizador de polvo, y dicho agente se inyecta en la aleaci\u00f3n de aluminio con nitr\u00f3geno. El interior del l\u00edquido se somete a una operaci\u00f3n de purificaci\u00f3n en estado fundido, y la escoria se elimina tras 15 minutos de pulverizaci\u00f3n. Una vez completada la eliminaci\u00f3n de la escoria, se deja reposar.<\/p>\n

\"Tratamiento<\/p>\n

El valor de inclusiones de escoria del aluminio fundido es mayor justo despu\u00e9s de la eliminaci\u00f3n de la escoria en el horno de reposo. A medida que aumenta el tiempo de reposo, el valor de inclusiones de escoria del aluminio fundido muestra una disminuci\u00f3n gradual. Cuando el tiempo de reposo es de 15 minutos, el valor de inclusi\u00f3n de escoria del aluminio fundido alcanza b\u00e1sicamente un valor bajo, y cuando es superior a 15 minutos, dicho valor se mantiene b\u00e1sicamente estable, con una variaci\u00f3n m\u00ednima.<\/p>\n

A medida que aumenta el tiempo de reposo, la tasa de defectos por inclusiones de escoria de la aleaci\u00f3n muestra una tendencia a la baja. La tasa de defectos por inclusiones de escoria alcanza su m\u00e1ximo una vez finalizada la eliminaci\u00f3n de la escoria del horno de reposo. Durante los primeros 25 minutos, la tasa de defectos descendi\u00f3 significativamente y, a continuaci\u00f3n, se estabiliz\u00f3 pr\u00e1cticamente, situ\u00e1ndose en un 0,051 TP3T.<\/p>\n

Cuando el tiempo de reposo es de 15 minutos, el nivel de inclusiones de escoria en el aluminio fundido alcanza b\u00e1sicamente un valor bajo, y cuando supera los 15 minutos, dicho nivel se mantiene b\u00e1sicamente estable. Cuando el tiempo de reposo es superior a 25 minutos, la tasa de defectos se mantiene b\u00e1sicamente estable. Cuando el aluminio fundido reposa durante m\u00e1s de 25 minutos, su limpieza puede alcanzar un mejor estado; es decir, se puede dejar reposar el aluminio fundido durante al menos 25 minutos antes de trasladarlo a la siguiente estaci\u00f3n.<\/p>","protected":false},"excerpt":{"rendered":"
