Abstract
PURPOSE:To obtain high cooling effect in the initial period of cooling by supplying helium gas from one of branch pipes thereby forming a fluidized bed. CONSTITUTION:The material to be treated A which has been heated up to its hardening temperature is charged into the fluidized bed B1 in a treating furnace 2. At this time, the 1st valve 9 is opened and the 2nd valve 10 is closed to turn the fluidizing gas of the fluidized bed B1 to helium. The fluidized bed B2 of a furnace 1 is fluidized by air through the feed pipe 5 for air. Upon completion of the cooling of the initial period of the material to be treated A, the 1st valve 9 is closed and the 2nd valve 10 is opened to turn the fluidized gas of the fluidized bed B1 to air or nitrogen gas. Upon perfect cooling of the material to be treated A after this, the material to be treated A is taken out from the fluidized bed B1.
