A la hora de seleccionar la composici\u00f3n del agente de refinado del aluminio l\u00edquido, adem\u00e1s de las propiedades f\u00edsicas del agente de refinado (como el punto de fusi\u00f3n, la viscosidad, la tensi\u00f3n superficial, la densidad, la volatilidad, etc.), tambi\u00e9n deben tenerse en cuenta las caracter\u00edsticas de la interacci\u00f3n qu\u00edmica entre el agente de refinado, el metal y el medio gaseoso, de modo que tenga una gran capacidad para absorber y disolver inclusiones, un punto de fusi\u00f3n bajo y un buen rendimiento en la separaci\u00f3n entre la escoria y el aluminio, y permita que determinados componentes del agente de refinado modifiquen las propiedades del gas del horno al calentarse y fundirse, formando una atm\u00f3sfera reductora que reduzca la oxidaci\u00f3n del aluminio.<\/p>\n

Funci\u00f3n del agente refinador de aluminio l\u00edquido<\/h2>\n

(1) Favorece la eliminaci\u00f3n de la pel\u00edcula de \u00f3xido en la interfaz entre el aluminio fundido y el agente de refinado, as\u00ed como la eliminaci\u00f3n de inclusiones y gases.
\n(2) Es f\u00e1cil que reaccione con el aluminio fundido, lo que favorece la destrucci\u00f3n de la pel\u00edcula de \u00f3xido, y el hidr\u00f3geno puede escapar de la superficie del aluminio fundido.
\n(3) Tiene la funci\u00f3n de disolver y adsorber las inclusiones, lo que favorece la eliminaci\u00f3n de estas y de los gases.<\/p>\n

\"Aluminio<\/p>\n

Cuando el fundente de refinado<\/a> Si su funci\u00f3n principal es protectora, se debe seleccionar una sal de cloruro que sea inerte frente al aluminio fundido. Cuando el objetivo principal sea la purificaci\u00f3n mediante desgasificaci\u00f3n, se debe seleccionar un fundente de refinado que reaccione eficazmente con el aluminio fundido para generar sustancias gaseosas. Cuando se utiliza principalmente para eliminar inclusiones, debe tenerse plenamente en cuenta la capacidad de descarga de escoria del agente de refinado.<\/p>\n

Entre las sales de cloruro m\u00e1s utilizadas en la producci\u00f3n se encuentran el cloruro de zinc, el cloruro de manganeso, el cloruro de potasio, el cloruro de sodio, el hexacloroetano y el tetracloruro de carbono, entre otras, que pueden emplearse solas o en combinaci\u00f3n. Si se requiere que el agente de refinado no solo purifique, sino que tambi\u00e9n modifique o refine los granos cristalinos, se puede utilizar un agente de refinado compuesto, formado por la adici\u00f3n de agentes modificadores y de refinado, para lograr el objetivo de un tratamiento integral del aluminio fundido.<\/p>","protected":false},"excerpt":{"rendered":"
