Abstract

L'invention concerne la structure de la zone inférieure d'un four métallurgique (1), comprenant une partie inférieure (2) et une paroi (3) dotées toutes deux d'une structure en acier (6, 21) formant la surface externe, et une garniture intérieure (12) de briques réfractaires. La partie inférieure (2) et la paroi (3) sont reliées ensemble. La paroi (3) du four (1) est divisée en parties inférieure (4) et supérieure (30), la structure en acier (21) de la partie inférieure (4) constituant un anneau séparé composé de parties (23), et des joints (19) étant prévus entre lesdites parties (23) et agencés afin de s'étendre. L'invention concerne également un procédé permettant de commander l'expansion du four (1).
