ABSTRACT:
Coils of strip to be annealed are placed in a furnace with their eye vertical and are heated to the annealing temperature by heating elements on the furnace above and below the level of the coils. An improved convector coil support includes a single metal plate having a central opening and grooves in one side extending from the central opening to the outer periphery when used to support a bottom coil and two such plates fastened together with their grooves facing each other when the convector is used to support a coil on top of a coil.
