Abstract
Four électrique à résistance à moufle permettant d'atteindre des températures de l'ordre de 1000 à 2 000 degrés C sans modifier les résistances. L'élément de résistance 5 est constitué par du graphite en poudre compact et fixé par un couple d'anneaux 6 en graphite solide qui constituent les organes de fermeture de l'interstice 4 et les organes de transmission du courant électrique à l'élément de résistance 5; lesdits anneaux 6 présentant des zones métallisées 7 au contact de zones métallisées 1a, 2a; 1b, 2b des parois adjacentes desdits éléments tubulaires réfractaires 1, 2.
