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.

1. An insulated, self-annealing enclosure for heated sheet metal coils, comprising: a. an enclosure body for encasing and supporting one or more heated coils, having an open bottom for receiving the heated coils; and b. a floor that sealingly engages the open bottom of the enclosure body; wherein the enclosure body comprises two enclosure halves, each half having an open bottom to receive the heated coils and sealing means to sealingly engage the floor and to sealingly engage with one another.

2. The self-annealing closure of claim 1 having dimensions of from 100 inches to 110 inches in length, from 100 inches to 110 inches in depth and from 100 inches to 110 inches in height.
