Abstract
This invention provides a spacer for vertically separating coils in an annealing furnace. The spacer includes a lower segmental plate and an upper segmental plate, and ribs between the segmental plates and affixed thereto. A porous medium is disposed between the segmental plates, so that the porous medium can be heated by hot gas passing through it, and can then radiate heat to the inside surfaces of the segmental plates.
