Abstract

1,220,978. Annealing furnaces. UNITED STATES STEEL CORP. 1 Nov., 1968 [2 Nov., 1967,] No. 51990/68. Heading F4B. The depending skirt 8 of a removable cover 6 in a coil annealing furnace is sealed in a peripheral trough 12 surrounding the base 10 of the furnace by a flexible woven tube 22 of ceramic strands reinforced with metal resistant to oxidation at high temperatures and having bulk ceramic filler 24 in the tube. The tube extends completely around the trough and is in contact with both side walls of the trough. The base has plates 16 secured thereto which taper downwardly and outwardly to form guides 18 for the cover.
