摘要： A treatment chamber for heating and pressing workpieces and a heat insulating structure which covers the treatment chamber sideways and from above are provided within a high-pressure vessel. Below the treatment chamber are disposed a base heater for heating a pressure medium gas and a fan for supplying the pressure medium gas in a heated state into the treatment chamber and stirring the heated gas. The workpieces can be held on the heat insulating structure side, and the heat insulating structure and the workpieces can be taken out from the interior of the high-pressure vessel and can be conveyed together separately from a lower lid of the high-pressure vessel. A hot isostatic pressing apparatus is provided less expensively which can heat and press workpieces at a relatively low temperature of not higher than 600° C. Besides, it is possible to shorten the cycle time in HIP.

摘要： While a workpiece is heated and pressed by one of a pair of high-pressure vessels, a workpiece being pressed by the other high-pressure vessel is placed in a heated state. In the reducing process after termination of heating and pressing treatment of the workpiece by one high-pressure vessel, both the high-pressure vessels are placed in communication, and the pressure medium gas released from one high-pressure vessel is poured into the other high-pressure vessel. After pressures of both the high-pressure vessels have assumed a nearly balanced state, the pressure medium gas is sucked out of one high-pressure vessel by a compressor and pressed, and is poured into the other high-pressure vessel, and the workpiece is heated and pressed by the other high-pressure vessel. By the method as described, considerable shortening of cycle time of HIP treatment is achieved, and the HIP treatment can be carried out with high efficiency.
