Description

Technical Field

[0002] The warm isostatic press is a hydraulic molding machine that is widely used in the molding process of ceramic component blocks. Its working principle is to use liquid medium to pressurize and heat the ceramic component blocks in the pressure vessel, and to uniformly apply temperature and pressure to the ceramic component blocks through the liquid medium, so that they are compacted under pressure.

[0003] The warm isostatic press in the prior art first heats the working medium to the required temperature, then puts the ceramic component bar into the container, and then closes the container cover and pressurizes it to the required ultra-high pressure value in the cylinder, thereby compacting the ceramic component bar at a certain temperature and pressure, and finally releases the pressure at this temperature and opens the cylinder cover to take out the pressed ceramic component bar, so the working medium temperature of the bar is the set temperature from beginning to end. However, some special ceramic component bars need to be compacted by pressure under normal temperature and high pressure conditions first, and then heated by heating the medium in the cylinder to meet their process requirements, and after the heat and pressure holding state is over, it is necessary to hold the pressure until the temperature drops before the pressure is released, the cylinder cover is opened, and the compacted ceramic component bar is taken out.
