Abstract
An annealing base for hood-type annealing furnaces comprises a support (6) receiving the annealing goods, in particular stacked sheet metal coils. The support (6) rests on the distributor (4) of a central fan (5). The vertical fan axis is surrounded by a thermally insulating filling member (3). The load of the distributor (4) is transmitted by means of a supporting structure (9, 10) through the filling member (3) to a frame member (2) supported on the foundation (1). The filling member (3) consists of insulating wool or the like gas-tightly encapsulated in sheet metal. To avoid the formation of cracks in the filling member (3) during the annealing process, a stronger shaped ring (9) adapted to the bottom surface of the distributor (4) is inserted in the sheet metal constituting the capsule of the filling member (3), which shaped ring constitutes the supporting structure by means of two concentric sheet metal cylinders (10) connecting the same with the frame member (2).
