Title:
TEMPERATURE CONTROL METHOD AND TEMPERATURE CONTROL DEVICE OF WARM ISOTROPIC PRESSURE PRESSURIZING DEVICE
Document Type and Number:
Japanese Patent JP2003279264
Kind Code:
A
Abstract:
To solve a problem of difficulty in controlling a temperature of a pressure medium because the pressure medium is liquid and a heater in a pressure vessel can not be arranged, when performing pressurizing processing in this pressure vessel by filling the pressure medium composed of the liquid in the pressure vessel together with a processing object in a warm isotropic pressure pressurizing device.
A pressure medium temperature in the pressure vessel 3 is measured, and a pressure increasing-decreasing speed to the inside of the pressure vessel 3 is controlled on the basis of a temperature difference obtained by comparing this measured temperature with a prescribed preset temperature.
