Qu'est-ce qu'un agent de recouvrement de louche ?<\/strong><\/p>\n

Agents de recouvrement des louches<\/strong><\/a> sont des mat\u00e9riaux fonctionnels utilis\u00e9s pour recouvrir la surface de l'acier en fusion dans les poches de coul\u00e9e pendant la fabrication de l'acier :<\/p>\n

Isolation thermique : R\u00e9duire la perte de chaleur pour maintenir la stabilit\u00e9 de la temp\u00e9rature de la coul\u00e9e ;
\nAnti-oxydation : Isolation de l'air pour \u00e9viter l'oxydation secondaire de l'acier en fusion ;
\nAdsorption d'inclusion : Purification de l'acier fondu par des r\u00e9actions d'interface laitier-m\u00e9tal ;
\nAmortissement de l'impact : Att\u00e9nuation des \u00e9claboussures et de l'entra\u00eenement du laitier pendant le coulage de l'acier.<\/p>\n

\"\"<\/p>\n

Composants typiques des agents de couverture des poches de coul\u00e9e :<\/strong><\/p>\n

Leurs composants typiques sont domin\u00e9s par Al\u2082O\u2083, SiO\u2082 et CaO, compl\u00e9t\u00e9s par des agents chauffants (p. ex. poudre d'Al) et des mat\u00e9riaux d'isolation thermique l\u00e9gers (p. ex. billes de flottage).<\/p>\n

Class\u00e9s par fonction des agents de couverture des poches de coul\u00e9e :<\/strong><\/p>\n

Type g\u00e9n\u00e9rateur de chaleur : Compense la perte de temp\u00e9rature par des r\u00e9actions exothermiques, convient pour les coul\u00e9es de longue dur\u00e9e ou les nuances d'acier \u00e0 basse temp\u00e9rature ;
\nType d'isolation : Utilise des mat\u00e9riaux \u00e0 faible conductivit\u00e9 thermique comme matrice, en mettant l'accent sur la pr\u00e9servation de la chaleur \u00e0 moindre co\u00fbt ;
\nType composite : Int\u00e8gre \u00e0 la fois la production de chaleur et l'isolation, s'adaptant ainsi aux exigences de processus complexes.
\nExigences de performance : Point de fusion <1200\u00b0C, faible viscosit\u00e9, basicit\u00e9 (CaO\/SiO\u2082) 1,0-1,5, et capacit\u00e9 de formation rapide du laitier.<\/p>\n
