ABSTRACT:
A batch annealing apparatus comprises a bell-shaped furnace, a base plate, an inner cover, plus a bottom chamber that opens upward, has an inside diameter slightly larger than the outside diameter of a metal coil to be treated therein, is capable of accommodating the metal coil, and disposed below the furnace. A cylindrical stationary base coaxially extends upward from the bottom of the bottom chamber. The stationary base has a partition with an outside diameter slightly smaller than the inside diameter of the metal coil that is formed at a point corresponding to the opening of the bottom chamber. The base plate is annular in shape, equipped with cooling means, and supported by elevatable supporting means that passes through the bottom of the bottom chamber. The lower end of the supporting means is connected to an elevating device.
