El fundente para la fundici\u00f3n de aluminio es una sustancia s\u00f3lida (normalmente una mezcla de sales de cloruro y fluoruro) que se utiliza en las fundiciones de aluminio para reducir la oxidaci\u00f3n del metal fundido, minimizar la penetraci\u00f3n de hidr\u00f3geno atmosf\u00e9rico, y absorber las inclusiones no met\u00e1licas suspendidas en el ba\u00f1o fundido, mantener las paredes del horno y la cuchara libres de \u00f3xidos acumulados, reducir el contenido de aluminio arrastrado en la escoria de aluminio, eliminar el hidr\u00f3geno disuelto en el ba\u00f1o fundido, refinar los granos de aluminio durante la solidificaci\u00f3n, modificar las inclusiones de silicio en las aleaciones que contienen silicio y oxidar el exceso de magnesio.<\/p>\n

En el proceso de fundici\u00f3n del aluminio y las aleaciones de aluminio, las inclusiones de hidr\u00f3geno y \u00f3xido son las principales sustancias que contaminan la masa fundida de aluminio. El aluminio forma f\u00e1cilmente Al\u2082O\u2083 o al\u00famina secundaria (Al\u2082O y AlO) con el ox\u00edgeno, y tambi\u00e9n absorbe f\u00e1cilmente gas (H), que representa entre el 70 y el 90% del gas total presente en el fundido de aluminio.<\/p>\n

Los principales defectos de las aleaciones de aluminio fundido se deben a part\u00edculas s\u00f3lidas, como poros e inclusiones de escoria. Por lo tanto, para obtener una masa fundida de alta calidad, no solo es necesario elegir un proceso de fundici\u00f3n adecuado y razonable, sino que tambi\u00e9n son muy importantes el refinado y la purificaci\u00f3n de la masa fundida.<\/p>\n

\"Fundente<\/p>\n

Flujo granular<\/a> Es un aditivo nuevo, eficaz y respetuoso con el medio ambiente. Se utiliza en el proceso de refinado secundario de la fundici\u00f3n y la colada de aleaciones de aluminio. Su contenido en hidr\u00f3geno reduce la p\u00e9rdida de aluminio.<\/p>\n

A diferencia de los tradicionales fundente en polvo<\/a>, el fundente granular de aleaci\u00f3n de aluminio presenta evidentes ventajas t\u00e9cnicas y beneficios econ\u00f3micos. Al mismo tiempo, durante la reacci\u00f3n con el aluminio fundido, el gas liberado por el fundente granular no es t\u00f3xico y genera muy pocos gases de escape, lo que mejora considerablemente el entorno de producci\u00f3n.<\/p>\n

Dadas las ventajas mencionadas anteriormente, los fundentes granulados de aleaci\u00f3n de aluminio han suscitado cada vez m\u00e1s inter\u00e9s en el sector y tienden a sustituir progresivamente a los fundentes en polvo tradicionales.<\/p>\n

AdTech detallado fundente para la fundici\u00f3n de aluminio<\/a> Se presenta en dos especificaciones: PM02 y PM06. Es un granulado de color blanco (ligeramente gris\u00e1ceo). Incorpora una tecnolog\u00eda exclusiva para mejorar eficazmente el proceso de desgasificaci\u00f3n y la eliminaci\u00f3n de escorias y metales alcalinos del metal fundido.<\/p>","protected":false},"excerpt":{"rendered":"
