Sin embargo, durante el proceso de uso de cloro, cloruro o fluoruro, se producir\u00e1 una fuga de cloro gaseoso del aluminio fundido, as\u00ed como cloro gaseoso y fluoruro de hidr\u00f3geno generados tras la reacci\u00f3n con metales alcalinos, y el hexacloroetano y el tetracloruro se gasificar\u00e1n al calentarse, produciendo gas de carb\u00f3n que da\u00f1ar\u00e1 gravemente el revestimiento del horno y acortar\u00e1 su vida \u00fatil; en segundo lugar, supondr\u00e1 riesgos laborales para los operarios de producci\u00f3n.<\/p>\n![\"Eliminaci\u00f3n](\"http:\/\/alalloycasting.com\/wp-content\/uploads\/2020\/09\/Alkali-Metals-Removal-1.jpg\")

Mediante una reacci\u00f3n de sustituci\u00f3n se ha logrado un m\u00e9todo respetuoso con el medio ambiente y eficiente para la obtenci\u00f3n de metales alcalinos y alcalinot\u00e9rreos. El principio b\u00e1sico consiste en aprovechar las caracter\u00edsticas de la actividad qu\u00edmica de los metales alcalinos y alcalinot\u00e9rreos, seg\u00fan su orden de actividad, y a\u00f1adir sales de otros metales con cationes relativamente inactivos, para posteriormente eliminarlos mediante otros m\u00e9todos f\u00edsicos.<\/p>\n
En la actualidad, las aleaciones de alto rendimiento est\u00e1n evolucionando hacia especificaciones de mayor tama\u00f1o, y los requisitos dimensionales de las palanquillas de fundici\u00f3n est\u00e1n aumentando gradualmente. Los riesgos que plantean los gases residuales, las impurezas, la escoria y los metales alcalinos y alcalinot\u00e9rreos presentes en la masa fundida de aleaci\u00f3n de aluminio durante el procesamiento de las palanquillas de fundici\u00f3n cobrar\u00e1n a\u00fan m\u00e1s relevancia.<\/p>","protected":false},"excerpt":{"rendered":"
