ABSTRACT:
A heat treatment apparatus for metals or metal articles has a fluidized-bed furnace for heating the metals and a cooling chamber disposed above the furnace so as to communicate with a heating chamber of the furnace through a partition capable of being opened and closed, so that the metals can be cooled immediately after heated. The apparatus further includes a circulating circuit arrangement with a heat-resisting fan for circulating together or separately heated furnace gas and cooling fluid. Flow rate of the circulating furnace gas and/or cooling fluid is controlled by a flow rate control device provided in the circulating circuit.
