The invention relates to a pusher furnace (1) for the annealing treatment of aluminum bars for instance. Rails (7) with plate-shaped sliding supports (8) are provided. Said supports cover the entire width of the rails (7) and are produced with grooves (12) on the upper sides thereof. The grooves extend in the longitudinal direction of the rails (7) in an arrow-shaped manner and serve for receiving driven material. Several sliding supports (8) are juxtaposed and thereby form arrow-shaped expansion joints. The rails (7) and the sliding supports (8) can be easier produced and assembled by virtue of the inventive embodiment of said rails (7) and sliding supports (8). Furthermore, the material (10) can be transported without jolts in as far as possible, whereby said material is mounted on sliding shoes (9).
Pusher furnace with rails (7) and with sliding shoes (9) which are guided displaceably on these and carry the treatment material to be transported through the furnace, sliding supports (8) which have grooves (12) for receiving material abrasion being provided on the rails (7), characterized in that the sliding supports (8) are of plate-shaped design, in each case fully cover the rails (7) over their width and are provided on their top sides with grooves (12), running in an arrow shaped manner in the longitudinal direction of the rails (7), for receiving material abrasion, and in that a plurality of sliding supports (8) are lined up with one another to form arrow-shaped joints, the cross section of the joints corresponding essentially to that of the grooves.
