Abstract (en)
[origin: EP0331937A1] The chamber of the furnace is designed with a longitudinally continuous roll bed. The furnace (10) has a hot upper furnace chamber (11), a lower furnace chamber (12) and in between a hearth floor (13) with openings (14). The roll bed is mounted essentially in the lower furnace chamber (12) below the hearth floor (13) and projects only with small sections of its furnace rolls (17) through the openings (14) of the hearth floor (13) above the level (N) of the latter. At least the roll sections, projecting into the hot zone, having the running surface (19), on which the materials to be heated (20) are transported, consist of particularly heat-resistant material which, assembled from segments to form a ring (18), surrounds the furnace rolls (17) on the circumferential surface. Cleaning devices (23, 24, 25) free the running surfaces (19) of the furnace rolls (17) of disturbing scale caking. <IMAGE>
