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.

Abstract translation: 本发明提供了一种线圈退火炉，其中气氛从封闭线圈的盖子外循环并经由外部回路循环，然后返回到盖子，其中热交换器位于外部回路中，但物理上可移动，使得当移出时 电路的自由循环没有障碍，例如当热交换器在电路中时不可避免地提供自由循环，并且在盖和炉结构之间的密封件包括被压缩的压缩橡胶圈，以防止 当热交换器移入电路时，通过压力波动密封失效。
