HOT ISOSTATIC PRESSING DEVICE

摘要

PURPOSE:To prevent a cooling rate from being lowered after a heat accumulator reaches an equilibrium temp. at the time of cooling a furnace gas with the heat accumulator. CONSTITUTION:A heat accumulator 13 is provided between the lower surface of an upper lid 2 and the upper surface of a heat insulating layer 8 to cool a gaseous pressure medium in a furnace chamber 9 in the insulating layer 8. A passage 16 for the high-temp. furnace gas in the furnace chamber 9 and plural vertical passages 18 piercing the accumulator 13 are formed in the accumulator 13.
