Beschreibung
Zusammenfassung:	The invention consists primarily in a multi-shelf furnace (1), intended for thermally treating a charge of material M, comprising at least one rabble arm (5) secured to a rotary shaft, above each shelf (3) of the furnace, and comprising rabble teeth (7) secured perpendicularly to the arm, each rabble tooth (7) having a front edge that is inclined from bottom to top, the inclined front edge constituting the leading edge (70) for the material M to be rabbled. L'invention consiste essentiellement en un four à soles multiples (1), destiné à traiter thermiquement une charge de matière M, comprenant au moins un bras de râblage (5) fixé à un arbre rotatif, au-dessus de chaque sole (3) du four et comprenant des dents de râblage (7) fixées perpendiculairement au bras, chaque dent de râblage (7) présentant une arête avant qui est inclinée du bas vers le haut, l'arête avant inclinée constituant l'arête d'attaque (70) de la matière M à râbler.
