The best shaft location is slightly off the centerline of the crucible or ladle to help avoid vortex formation with its circular rotation in the liquid metal. An offset distance of 2-4 in. from the centerline is usually sufficient. The use of a baffle plate also is a good idea, because the baffle opposes the circulation movement of metal and reduces vortex formation.<\/p>\n<p>Una vez que el RID se encuentre en la posici\u00f3n correcta, se debe encender la unidad y ajustar la velocidad del eje a 300 RPM. El flujo de gas inerte tambi\u00e9n debe estar activado y, a continuaci\u00f3n, los operarios deben ajustar el caudal de gas y la velocidad del eje. El flujo de gas debe aumentarse hasta que se vean burbujas de gas flotando hacia la superficie del metal l\u00edquido. A medida que aumenta el flujo de gas, el tama\u00f1o de las burbujas debe ir aumentando.<\/p>\n<p>El resultado deseado es una buena dispersi\u00f3n de peque\u00f1as burbujas, manteniendo al mismo tiempo una superficie relativamente tranquila. Cuando se encuentre una combinaci\u00f3n \u00f3ptima entre el caudal y la velocidad de rotaci\u00f3n del eje, anote los par\u00e1metros para su uso futuro. Anote tambi\u00e9n el tiempo total de desgasificaci\u00f3n, que normalmente oscila entre cuatro y ocho minutos, a menos que las temperaturas sean muy altas o que la cantidad de gas necesaria sea baja.<\/p>\n<p><img class=\"alignnone wp-image-4269\" src=\"http:\/\/www.adtechamm.com\/wp-content\/uploads\/2019\/02\/Degassing-Molten-Aluminum.jpg\" alt=\"Desgasificaci\u00f3n del aluminio fundido\" width=\"450\" height=\"600\" srcset=\"https:\/\/www.adtechamm.com\/wp-content\/uploads\/2019\/02\/Degassing-Molten-Aluminum.jpg 600w, https:\/\/www.adtechamm.com\/wp-content\/uploads\/2019\/02\/Degassing-Molten-Aluminum-225x300.jpg 225w\" sizes=\"(max-width: 450px) 100vw, 450px\" \/><\/p>\n<p><strong>Clasificaci\u00f3n de las aleaciones de aluminio para fundici\u00f3n.<\/strong><br \/>\nCada aleaci\u00f3n de aluminio fundido se identifica mediante un n\u00famero de cuatro d\u00edgitos, con un punto decimal que separa el tercer y el cuarto d\u00edgito.<\/p>\n<p>El primer d\u00edgito indica el grupo de aleaciones seg\u00fan el principal elemento de aleaci\u00f3n:<\/p>\n<p>1xx.x Aluminio 99.0% como m\u00ednimo;<\/p>\n<p>2xx.x Cobre (4%\u20264.6%);<\/p>\n<p>Silicio 3xx.x (5%\u202617%) con cobre y\/o magnesio a\u00f1adidos;<\/p>\n<p>4xx.x Silicio (5%\u202612%);<\/p>\n<p>5xx.x Magnesio (4%\u202610%);<\/p>\n<p>7xx.x Zinc (6,2%\u20267,5%);<\/p>\n<p>8xx.x Esta\u00f1o;<\/p>\n<p>9xx.x Otros.<\/p>\n<p>Los dos d\u00edgitos siguientes identifican la aleaci\u00f3n de aluminio o indican la pureza de la aleaci\u00f3n.<\/p>\n<p>En las aleaciones de la serie 1xx.x, los dos \u00faltimos d\u00edgitos indican el nivel de pureza de la aleaci\u00f3n; coinciden con los dos d\u00edgitos situados a la derecha del punto decimal en la concentraci\u00f3n m\u00ednima de aluminio (en porcentaje): 150,0 significa un m\u00ednimo del 99,50% de aluminio en la aleaci\u00f3n; 120,1 significa un m\u00ednimo del 99,20% de aluminio en la aleaci\u00f3n.<\/p>\n<p>En todos los dem\u00e1s grupos de aleaciones de aluminio (desde 2xx.x hasta 9xx.x), los dos \u00faltimos d\u00edgitos indican las diferentes aleaciones que componen el grupo.<\/p>\n<p>El \u00faltimo d\u00edgito indica la forma del producto: pieza fundida (designada con un \u201c0\u201d) o lingote (designado con un \u201c1\u201d o un \u201c2\u201d, en funci\u00f3n de los l\u00edmites de la composici\u00f3n qu\u00edmica).<\/p>\n<p>Cualquier modificaci\u00f3n de la aleaci\u00f3n original o de los l\u00edmites de impurezas se indica mediante una letra de serie situada antes de la designaci\u00f3n num\u00e9rica.
