Title
(EN) ELECTRIC FURNACE WITH ECCENTRIC TAPHOLE AND PROCESS OF STEEL MAKING IN THIS FURNACE
(FR) FOUR A ARC ELECTRIQUE PRESENTANT UN TROU DE COULEE EXCENTRE, ET PROCEDE DE FABRICATION D'ACIER DANS CE FOUR
Abstract
(EN) The invention concerns an electric-arc furnace with an off-center taphole (26) through the bottom, designed for steel making and known under the name of an EBT furnace. It is comprised of a vat (4) for receiving the metal to be melted, and a protuberance (6) that prolongs the vat (4) laterally. A roof covers the protuberance (6). An upper wall prolongs the vertical wall of the vat (4). An arch (12) covers the upper walls of the vat (4), this arch (12) capable of being retracted laterally in a sweep zone, a taphole (26) being provided in the bottom of the provided protuberance (6). A closure device for the taphole (26) is comprised of a stopper (32), handling means for displacing the stopper (32) between a rest position, a waiting position in which the lower end of the stopper (32) is close to the taphole (26), and a closure position in which the stopper (32) closes off the entrance to the taphole (26), at least partially.
(FR) L'invention concerne un four à arc électrique lequel présente, sur son fond, un trou de coulée excentré (26), est conçu pour la fabrication d'acier, est connu sous le nom de four EBT et comprend une cuve (4) destinée à recevoir le métal à fondre, ainsi qu'une partie saillante (6) prolongeant latéralement la cuve (4). Un chapeau coiffe cette partie saillante (6). Une voûte (12) couvre les parois supérieures de la cuve (4) et peut être escamotée latéralement, à travers une zone prévue à cet effet. Un trou de coulée (26) est ménagé dans le fond de la partie saillante (6), un dispositif de fermeture de ce trou de coulée (26) se composant d'un bouchon (32), de moyens de manipulation et de déplacement de ce bouchon (32) entre une position de repos, une position d'attente dans laquelle l'extrémité inférieure du bouchon (23) se trouve à proximité du trou de coulée (26), et une position de fermeture dans laquelle le bouchon (32) ferme l'entrée du trou ce coulée (26), au moins partiellement.
