The disclosure relates to a vacuum sintering furnace having a lubricant eliminating section, sintering section and cooling section which are aligned in series and connected by connecting hood means to each other so that a workpiece may be directly transferred to the following section without exposure of the workpiece to outside air. The connecting hood means comprises doors for selectively opening and closing the boundaries between the neighboring sections. Furthermore, the lubricant eliminating section is provided with a lubricant trapping device mounted on an exhaust line connecting a furnace body and a vacuum pump to each other, thereby the stable operation of the vacuum pump is ensured.
