く使用できるようになるなどの利点がある。As described above, in the vertical coil heat treatment furnace of the present invention, the coil-shaped heat-receiving object is loaded into the furnace from the loading chamber formed below the furnace body provided with the opening / closing door on the hearth. High temperature gas inside the furnace does not easily leak out even if the inlet is wide open, so that the loss of atmospheric gas and the loss of heat energy during charging and extraction can be greatly reduced. Reduce running costs. Also,
Since the object to be heated can be charged from underground, there is an advantage that a wide charging space is not required in front of the furnace body as in the related art, and the ground can be widely used.
