CFF<\/a>) pour la fonderie d'alliages d'aluminium depuis 2012.<\/p>\nLe point de fusion naturel de nombreux \u00e9l\u00e9ments m\u00e9talliques est tr\u00e8s \u00e9lev\u00e9. La plage des points de fusion des m\u00e9taux peut varier, mais elle s'\u00e9tend g\u00e9n\u00e9ralement de quelques centaines de degr\u00e9s Celsius \u00e0 plus de mille degr\u00e9s Celsius. Par cons\u00e9quent, le filtre en mousse c\u00e9ramique pour fonderie Alumar doit pr\u00e9senter une excellente r\u00e9sistance \u00e0 l'attaque et \u00e0 la corrosion par le m\u00e9tal en fusion.<\/p>\n
La porosit\u00e9 correspond au pourcentage d'espace poreux dans le filtre en mousse c\u00e9ramique Cff. Cette caract\u00e9ristique est tr\u00e8s importante pendant le fonctionnement, car des filtres pr\u00e9sentant une porosit\u00e9 trop \u00e9lev\u00e9e ou trop faible peuvent compliquer le processus. Il est donc recommand\u00e9 de choisir la porosit\u00e9 optimale en fonction du type de m\u00e9tal fondu utilis\u00e9.<\/p>\n
Le filtre en mousse c\u00e9ramique pour fonderie Alumar est un corps c\u00e9ramique poreux pr\u00e9sentant une porosit\u00e9 \u00e9lev\u00e9e et une structure r\u00e9ticulaire tridimensionnelle, se pr\u00e9sentant sous la forme d\u2019une mousse durcie ou d\u2019une \u00e9ponge de porcelaine. Gr\u00e2ce \u00e0 sa porosit\u00e9 \u00e9lev\u00e9e, \u00e0 sa grande surface sp\u00e9cifique, \u00e0 sa r\u00e9sistance \u00e0 la chaleur, \u00e0 sa r\u00e9sistance aux temp\u00e9ratures \u00e9lev\u00e9es, \u00e0 sa r\u00e9sistance \u00e0 la corrosion chimique, \u00e0 sa bonne r\u00e9sistance m\u00e9canique et \u00e0 ses performances d'adsorption, ce filtre peut \u00eatre largement utilis\u00e9 pour la purification des fonderies d'Alumar.<\/p>\n
L'activit\u00e9 de r\u00e9duction d'Alumar est contr\u00f4l\u00e9e conjointement par Alcoa Alum\u00ednio (60%) et South32 (40%). Elle dispose de trois lignes de production d'\u00e9lectrolyseurs d'une capacit\u00e9 op\u00e9rationnelle totale de 447 000 tonnes m\u00e9triques, dont 268 000 tonnes m\u00e9triques attribuables \u00e0 Alcoa.<\/p>\n

Alcoa pr\u00e9voit de remettre en service la capacit\u00e9 inutilis\u00e9e de sa fonderie Alumar \u00e0 S\u00e3o Lu\u00eds, au Br\u00e9sil, qui avait \u00e9t\u00e9 enti\u00e8rement r\u00e9duite depuis 2015. Une fois pleinement op\u00e9rationnelle, la ligne de production remise en service pourra produire jusqu\u2019\u00e0 268 000 tonnes d\u2019aluminium par an.<\/p>\n
La relance de la r\u00e9duction devrait co\u00fbter environ $ 75 millions de dollars am\u00e9ricains, dont environ $ 10 millions de dollars am\u00e9ricains de d\u00e9penses d'investissement. La remise en service \u00e9tant presque achev\u00e9e, l'usine emploiera plus de 750 salari\u00e9s, en plus des 850 salari\u00e9s directs de la raffinerie d'alumine situ\u00e9e sur le m\u00eame site.<\/p>\n
Outre la reprise de la production, Alcoa a \u00e9galement soulign\u00e9 que d'ici 2024, elle pr\u00e9voit d'utiliser 100% d'\u00e9nergie renouvelable pour alimenter la fonderie d'Alumar.<\/p>","protected":false},"excerpt":{"rendered":"
