PURPOSE:To enable to heat each coiled articles as uniform as possible by opposing twist and rotary directions of blades of each recirculating fans provided to the ceiling part of a heating and soaking chamber or a cooling chamber so as to be corresponded directly above each coiled articles between adjacent ones. CONSTITUTION:Plural coiled articles (a) placed on a tray (b) is moved through a heating and soaking chamber B and a cooling chamber C from a charging apparatus A to be taken out therefrom. In this case, adjacent ones of plural recirculating fans 24a, 24b, 24c, 36a, 36b, 36c provided to the ceiling parts of the chamber B and C have rotary blades mutually twisted to opposed directions. By this mechanism, even if each recirculating fans are provided in close proximity, they are not interfered mutually and each coiled articles (a) can be simultaneously heated or cooled uniformly. |
