Abstract

La présente invention concerne le domaine de la sidérurgie, notamment la production de lingots lors de processus de transformation en aciéries. Le lingot se compose de fonte durcie dans laquelle ont été mélangés des nodules de minerai de fer. Ce lingot contient du fer reconstitué à partir des nodules dans une proportion allant de 7,5 à 15 % en poids de ces derniers, et comporte des zones ayant une concentration réduite en charbon. La surface du lingot se présente sous la forme de fonte monolithique. Le procédé de fabrication de ces lingots consiste à effectuer un remplissage dosé de moules (2) reliés entre eux à l'aide d'un doseur de calibrage (5), lesquels moules sont disposés sur un transporteur incliné (1). Le remplissage s'effectue d'abord à l'aide de fractions fines (jusqu'à 5,0 mm) puis de fractions plus importantes (jusqu'à 25,0 mm) de nodules de minerai de fer. Les moules (2) sont ensuite remplis de fonte fondue par un système de déversement d'un moule (2) dans un autre à l'aide d'un bec verseur (10) et dans le sens de déplacement desdits moules (2). Les moules (2) sont ensuite rapidement refroidis par dessous dès leur remplissage avec les nodules jusqu'au début de solidification de la fonte à la surface de contact du moule. Les moules (2) sont enfin refroidis par le dessus lors de leur passage dans la section finale du transporteur (1) avant que ne soient déchargés les lingots.
