る。Prior Art Conventionally, an annealing furnace using an inner cover has been used for atmospheric annealing of cold-rolled coils.
FIG. 1 is a schematic diagram showing a conventional annealing furnace. It consists of an outer furnace 1, a base 3 on which coils 2 are stacked in several stages, an inner cover 4 that directly covers the coils 2, and a fan equipment 5 that is installed on the base 3 and circulates atmospheric gas inside the inner cover 4. The outer furnace 1 is heated from the outside with a heating equipment 6 such as a burner or a radiant tube, and the atmospheric gas inside the inner cover 4 is propagated and heated, and the coil 2 is heated while circulating the atmospheric gas with the fan equipment 5. It is annealed by heating. In addition, 7 is a top Olius plate, and 8 is a coil spacer.

ツキが生じているのが実状である。 As shown in the figure, such a conventional inner cover 4 is a cylindrical body with an open bottom, and heated atmospheric gas is circulated at high speed between the inner cover 4 and the coil 2 and around the inner and outer circumferences of the coil 2 by a fan equipment 5. However, the atmospheric gas blown out from the base 3 flows upward while absorbing heat from the side wall of the inner cover 4 and transfers heat to the coil 2 by convection, so the upper part of the inner cover 4 becomes hotter than the lower layer coil. The upper layer coil has a higher temperature of around 100℃,
The reality is that there are variations in mechanical properties between coils subjected to the same annealing process.
