Title
(EN) VESSEL FOR CONTAINING DIRECT REDUCED IRON
(FR) RÉCIPIENT POUR CONTENIR DU FER DE RÉDUCTION DIRECTE
Abstract
(EN)
A vessel (10) for containing direct reduced iron (DRI), such as a reactor for the production of DRI, a bin or a hopper or other container for storing or feeding DRI to melting furnaces or briquetting machines, comprises at least an upper zone (11), defined by a first lateral wall (13) having a substantially cylindrical tubular shape, and a discharge zone (12), positioned below the upper zone (11) and defined by a second lateral wall (16) having a substantially truncated cone shape converging toward a lower discharge aperture (15). The second lateral wall (16) has an internal surface at least partly lined by an internal lining (22).
(FR)
La présente invention concerne un récipient (10) pour contenir du fer de réduction directe (FRD), tel qu'un réacteur pour la production de FRD, un bac ou une trémie ou un autre récipient pour stocker ou introduire du FRD dans des fours de fusion ou des machines de briquetage, comprenant au moins une zone supérieure (11), définie par une première paroi latérale (13) ayant une forme tubulaire sensiblement cylindrique, et une zone de décharge (12), positionnée au-dessous de la zone supérieure (11) et définie par une seconde paroi latérale (16) ayant une forme de cône sensiblement tronqué convergeant vers une ouverture de décharge inférieure (15). La seconde paroi latérale (16) a une surface interne au moins partiellement revêtue par une doublure interne (22).
