Abstract

Le procédé d'ouverture du trou de coulée d'un four à cuve par extraction d'une tige (22) , retenue dans la masse de bouchage durcie (24) du trou de coulée consiste à engager un moyen d'accouplement (36) sur l'extrémité de la tige (22), à saisir la tige (22) à l'aide d'une pince (46) déplaçable longitudinalement par un vérin hydraulique (42), à retirer la tige (22) d'une longueur correspondant à la course du vérin (42) et à répéter cette opération jusqu'à ce que la tige soit extraite complètement du trou de coulée. The method of opening the tap hole of a shaft furnace by extraction of a rod (22), retained in the hardened plugging mass (24) of the tap hole consists in engaging a coupling means (36) on the end of the rod (22), to grasp the rod (22) at using a clamp (46) movable longitudinally by a hydraulic cylinder (42), to remove the rod (22) of a length corresponding to the stroke of the jack (42) and repeat this operation until the rod is completely extracted from the tap hole.
