Abstract: The invention provides a coil annealing furnace in which atmosphere is circulated out of a cover enclosing the coils and via an external circuit before returning to the cover, in which a heat exchanger is located in the external circuit but is physically movable so that when moved out of the circuit there is no impediment to free circulation through the circuit such as is inevitably provided when the heat exchanger is in the circuit, and with a seal between the cover and furnace structure comprising a compressed rubber ring which is watercooled, so as to prevent seal failure through pressure fluctations when the heat exchanger is moved into the circuit.
