Title
(EN) SYSTEM TO PLUG THE DELTA AREA OF THE ROOF OF AN ELECTRIC ARC FURNACE
(FR) SYSTEME D'OBTURATION DU DELTA DE LA VOUTE D'UN FOUR A ARC ELECTRIQUE
Abstract
(EN)
System to plug the roof (10) of an electric arc furnace (11) having a main chamber or melting volume (25) arranged below the roof (10) and at least one electrode (15) introduced into the main chamber (25), the system comprising an upper element or auxiliary roof element (20) arranged on the top of the roof (10) and shaped so as to define an inner chamber (21) and at least a central aperture (113) through which the electrode (15) can be moved, the auxiliary roof element (20) consisting of a plurality of pipes (23) inside which a cooling fluid circulates under pressure.
(FR)
La présente invention concerne un système d'obturation de la voûte (10) d'un four à arc électrique (11) ayant une chambre principale ou volume destiné à la matière en fusion (25) située sous la voûte (10) et au moins une électrode (15) introduite dans la chambre principale (25). Ledit système comprend un élément supérieur ou élément de voûte auxiliaire (20) situé sur la partie supérieure de la voûte (10) et définissant une chambre intérieure (21), et au moins une ouverture centrale (113) par laquelle l'électrode (15) peut être déplacée. L'élément de voûte auxiliaire (20) comprend également plusieurs tubes (23) dans lesquels circule un liquide de refroidissement sous pression.
