ABSTRACT:
The present invention relates to a sintering furnace for powder metallurgy of cemented carbides, cermets and ceramics, which comprises a main furnace body, a heating chamber provided in the main body, a table having a moving means for carrying a workpiece in or out of the heating chamber and a means for cooling the interior of the furnace with a heat exchanger fitted to the exterior of the main furnace body, and a method for the sintering and heat treatment of cemented carbides in the sintering furnace as claimed in claim 1, which comprises sintering cemented carbides and cooling rapidly at a cooling rate of at least 30.degree. C./min from the sintering temperature being at least a temperature at which a liquid phase appears to at most 1000.degree. C. by the use of an inert gas as a coolant.
