Afin d'emp\u00eacher la r\u00e9oxydation des d\u00e9chets au cours du processus de fusion de l'aluminium, on utilise g\u00e9n\u00e9ralement une couche protectrice de flux, \u00e9galement appel\u00e9e \u00ab agent de recouvrement \u00bb, qui consiste \u00e0 recouvrir la surface des d\u00e9chets d'aluminium. Un agent de recouvrement largement utilis\u00e9 dans la fusion de l'aluminium est un m\u00e9lange de chlorure de potassium et de chlorure de sodium dans un rapport pond\u00e9ral de 1:1.<\/p>\n

L'aluminium et ses alliages sont largement utilis\u00e9s en raison de leurs propri\u00e9t\u00e9s uniques. Et avec le d\u00e9veloppement \u00e9conomique, la demande mondiale en aluminium n'a cess\u00e9 d'augmenter d'ann\u00e9e en ann\u00e9e. La consommation d'\u00e9quipements industriels mis au rebut et d'articles de premi\u00e8re n\u00e9cessit\u00e9 g\u00e9n\u00e8re \u00e9galement une grande quantit\u00e9 de d\u00e9chets d'aluminium. Afin de r\u00e9utiliser ces d\u00e9chets d'aluminium, ceux-ci sont recycl\u00e9s et renvoy\u00e9s vers le four de fusion pour \u00eatre refondus.<\/p>\n

L'agent de recouvrement destin\u00e9 \u00e0 la fusion de l'aluminium peut \u00eatre largement utilis\u00e9 dans le processus de fusion de l'aluminium m\u00e9tallique et de ses alliages. Il convient d'\u00e9taler une couche d'aluminium fondu sur les d\u00e9chets, puis d'\u00e9taler l'agent de recouvrement sur cette couche d'aluminium fondu. Cela permet de recycler les d\u00e9chets d'aluminium en aluminium fondu et d'utiliser un fondant pour traiter les scories.<\/p>\n

\"Fusion<\/p>\n

\u00c9tant donn\u00e9 que le point de fusion du flux de recouvrement<\/a> diminue, la phase liquide form\u00e9e \u00e0 une temp\u00e9rature plus basse emp\u00eachera l'oxydation des copeaux d'aluminium. D'autre part, comme le flux g\u00e9n\u00e8re une grande quantit\u00e9 de gaz de protection pendant le processus de chauffage, ces gaz r\u00e9agissent avec l'alumine pour former un film protecteur \u00e0 la surface de l'aluminium et de ses alliages. Ce film protecteur emp\u00eachera l\u2019oxyde d\u2019aluminium et ses alliages d\u2019\u00eatre expos\u00e9s \u00e0 l\u2019air. Par cons\u00e9quent, le flux de recouvrement utilis\u00e9 lors de la fusion de l\u2019aluminium offre un bon effet protecteur.<\/p>\n

Outre les agents de rev\u00eatement, notre entreprise propose \u00e9galement des agents d'affinage, des agents de scoriage, des solvants granul\u00e9s, etc.<\/p>\n

Le flux d'affinage pr\u00e9sente une bonne efficacit\u00e9 en mati\u00e8re de d\u00e9gazage et d'\u00e9limination des scories ; il est pulv\u00e9ris\u00e9 au fond du bain de fusion et r\u00e9agit physiquement et chimiquement avec les d\u00e9p\u00f4ts pr\u00e9sents au fond du four. Il s\u00e9pare les scories de l\u2019aluminium et fait remonter les gaz \u00e0 la surface de l\u2019aluminium en fusion afin de maintenir le fond du four propre. Cela r\u00e9duit consid\u00e9rablement la fr\u00e9quence des nettoyages du four, am\u00e9liore son taux d\u2019utilisation, diminue l\u2019intensit\u00e9 du travail, s\u00e9pare les oxydes et les impuret\u00e9s de la masse en fusion tout en la d\u00e9gazant, et les scories produites sont s\u00e8ches et faciles \u00e0 s\u00e9parer du m\u00e9tal. Le brise-scories am\u00e9liore le taux d\u2019utilisation du m\u00e9tal, r\u00e9duit l\u2019adh\u00e9rence des scories sur la paroi du four, facilite le nettoyage et l\u2019entretien du four, et am\u00e9liore l\u2019environnement de travail.<\/p>","protected":false},"excerpt":{"rendered":"
