Abstract

L'invention concerne une structure de four caractérisée principalement en ce que le corps du four est constitué d'une quantité appropriée de couches. Selon un mode de réalisation chaque couche est constituée d'une paroi extérieure cylindrique métallique et d'une paroi intérieure. Les deux extrémités de la paroi extérieure font saillie vers l'extérieur et présentent un rebord saillant perforé d'orifices traversants en nombre adéquat dans lesquels sont vissés des boulons et des écrous. Selon un autre mode de réalisation, la paroi intérieure en chamotte réfractaire moulée est montée à demeure sur le côté intérieur de la paroi extérieure par l'intermédiaire d'un cylindre en treillis métallique saillant. Selon un mode de réalisation différent, des nervures sont pratiquées entre les rebords saillants inférieur et supérieur du côté extérieur de la paroi du four.
