ABSTRACT:
An insulated, self-annealing enclosure is taught, having an enclosure body for encasing one or more heated sheet metal coils, having an open bottom for receiving the heated coils and a floor that sealingly engages the open bottom of the enclosure body. A method is also taught for batch production of annealed sheet metal coils by loading a first batch of coils into an annealing furnace and heating the coils to a predetermined temperature. Next, the heated coils are transferred to a self-annealing enclosure. A second batch of coils is then loaded into the annealing furnace. Finally, a method is described for annealing sheet metal coils, involving heating the coils in an annealing furnace to a predetermined temperature, then loading the heated coils into a self-annealing enclosure and holding the heated coils inside the enclosure for a predetermined length of time.
