ANNEALING BASE FOR HOOD-TYPE ANNEALING FURNACES

An annealing base for hood-type annealing furnaces com- prises a support (6) receiving the annealing goods, in par- ticular 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)....

Summary:An annealing base for hood-type annealing furnaces com- prises a support (6) receiving the annealing goods, in par- ticular 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 founda- tion (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 in- serted in the sheet metal constituting the capsule of the filling member (3), which shaped ring constitutes the sup- porting structure by means of two concentric sheet metal cylinders (10) connecting the same with the frame member (2).
