La temperatura de refinado y desgasificaci\u00f3n oscila entre 720 y 750 \u2103.<\/p>\n

La cantidad de agente refinador<\/a> Se calcula seg\u00fan la f\u00f3rmula 0,1%-0,2% de la masa total del aluminio fundido. Introd\u00fazcalo en el tanque de refinado, active el interruptor del pulverizador de polvo y deje entrar gas nitr\u00f3geno. Cuando el tubo de refinado comience a pulverizar, puede introducirlo hasta que 3\/4 del aluminio fundido del horno se mueva lentamente. Procure mantener la estabilidad, no deje zonas sin tratar y evite que el pulverizador toque el fondo del horno. La altura del chorro se mantiene por debajo de 15 mm y la duraci\u00f3n se controla por encima de los 15 minutos.<\/p>\n

Refinado, desgasificaci\u00f3n y formaci\u00f3n de escoria; dejar reposar entre 20 y 30 minutos antes de verter el aluminio fundido para la fundici\u00f3n.<\/p>\n

Una vez extra\u00edda la escoria de aluminio del horno, debe trasladarse r\u00e1pidamente al recipiente de escorificaci\u00f3n, y debe espolvorearse el agente de escorificaci\u00f3n sobre la escoria de aluminio seg\u00fan la dosis de 1-2 kg de agente de escorificaci\u00f3n por horno; a continuaci\u00f3n, debe realizarse inmediatamente la escorificaci\u00f3n, Para separar el metal de la escoria de aluminio, se vierte el aluminio fundido en el molde de hierro fundido y se deja solidificar en lingotes de aluminio listos para su uso.<\/p>\n

Durante el refinado, apaga la pistola de aceite del quemador y det\u00e9n el calentamiento.<\/p>\n

En la producci\u00f3n en continuo, tras llenar un horno con aluminio fundido, se cierra la v\u00e1lvula de salida de aluminio y se lleva a cabo el proceso de fusi\u00f3n en la parte inferior del horno.<\/p>\n

Si el efecto de refinado y desgasificaci\u00f3n no mejora, Adtech ofrece en l\u00ednea unidad de desgasificaci\u00f3n<\/a> y filtro de espuma cer\u00e1mica<\/a>\u00a0sistema de filtrado para la purificaci\u00f3n del aluminio fundido.<\/p>\n

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

Unidad de desgasificaci\u00f3n en l\u00ednea<\/strong> Se utiliza principalmente para la eliminaci\u00f3n de hidr\u00f3geno (H) y escorias del aluminio fundido. Se basa en el principio de flotaci\u00f3n por gas. El rotor introduce gas inerte o una mezcla de cloro y gas inerte en el aluminio fundido y fragmenta el gas en diminutas burbujas dispersas; estas burbujas ascienden hasta la superficie del aluminio fundido y, al mismo tiempo, completan la eliminaci\u00f3n de impurezas. El sistema de filtrado CFF se utiliza para filtrar y purificar el aluminio fundido, en combinaci\u00f3n con el filtro de espuma cer\u00e1mica. Permite filtrar las inclusiones y las part\u00edculas min\u00fasculas presentes en el aluminio fundido.<\/p>","protected":false},"excerpt":{"rendered":"
