CFF<\/a>) para la fundici\u00f3n de aleaciones de aluminio desde 2012.<\/p>\nEl punto de fusi\u00f3n natural de varios elementos met\u00e1licos es muy alto. El rango del punto de fusi\u00f3n de los metales puede variar, pero suele oscilar entre unos cientos de grados Celsius y m\u00e1s de mil grados Celsius. Por lo tanto, el filtro de espuma cer\u00e1mica para fundici\u00f3n de Alumar debe presentar una excelente resistencia al ataque y a la corrosi\u00f3n del metal fundido.<\/p>\n
La porosidad es el porcentaje de espacio poroso en el filtro de espuma cer\u00e1mica Cff. Esta caracter\u00edstica es muy importante durante el funcionamiento, ya que los filtros con una porosidad demasiado alta o demasiado baja pueden complicar el proceso. Por lo tanto, se recomienda seleccionar la porosidad ideal en funci\u00f3n del tipo de metal fundido que se utilice.<\/p>\n
El filtro de espuma cer\u00e1mica para fundici\u00f3n de Alumar es un cuerpo cer\u00e1mico poroso con alta porosidad y una estructura reticular tridimensional en forma de espuma endurecida o esponja de porcelana. Gracias a su elevada porosidad, su gran superficie espec\u00edfica, su resistencia al calor, su resistencia a altas temperaturas, su resistencia a la corrosi\u00f3n qu\u00edmica, su buena resistencia mec\u00e1nica y su capacidad de adsorci\u00f3n, este filtro puede utilizarse ampliamente en la purificaci\u00f3n de las fundiciones de Alumar.<\/p>\n
La planta de reducci\u00f3n de Alumar est\u00e1 controlada conjuntamente por Alcoa Alum\u00ednio (60%) y South32 (40%). Cuenta con tres l\u00edneas de producci\u00f3n de electrolizadores con una capacidad operativa total de 447 000 toneladas m\u00e9tricas, incluida la participaci\u00f3n de Alcoa de 268 000 toneladas m\u00e9tricas.<\/p>\n

<\/p>\n
Alcoa tiene previsto reactivar la capacidad inactiva de su fundici\u00f3n Alumar en S\u00e3o Lu\u00eds (Brasil), que se redujo por completo en 2015. Una vez que est\u00e9 plenamente operativa, la l\u00ednea de producci\u00f3n reactivada podr\u00e1 producir hasta 268 000 toneladas de aluminio al a\u00f1o.<\/p>\n
La reanudaci\u00f3n de la reducci\u00f3n de la producci\u00f3n tendr\u00e1 un coste aproximado de $ 75 millones de d\u00f3lares, incluidos aproximadamente $ 10 millones de d\u00f3lares en gastos de capital. Dado que la puesta en marcha est\u00e1 a punto de concluir, la planta dar\u00e1 empleo a m\u00e1s de 750 trabajadores, adem\u00e1s de los 850 empleados directos de la refiner\u00eda de al\u00famina situada en el mismo emplazamiento.<\/p>\n
Adem\u00e1s de reanudar la producci\u00f3n, Alcoa tambi\u00e9n ha destacado que, para 2024, tiene previsto utilizar 100% de energ\u00eda renovable para abastecer la fundici\u00f3n de Alumar.<\/p>","protected":false},"excerpt":{"rendered":"
