Abstract

Procédé et dispositif pour faciliter le remplacement des générateurs de plasma et pour diminuer les pertes calorifiques lors de l'installation d'un générateur dans un four à cuve, en particulier pour des générateurs de plasma du type comprenant des électrodes cylindriques entre lesquelles est engendré un arc électrique. Pour atteindre ce but, le bobinage (7) de champ entourant l'électrode la plus proche du nez (12) du générateur de plasma (11), avec ses connexions pour l'agent de refroidissement et l'électricité, est fixé de façon permanente dans la paroi (1) du four à cuve en conjugaison avec l'ouverture (6) pour l'introduction du générateur (11) de plasma dans le four à cuve.
