Setting the heating and pressurizing program:
(1) Setting the Heating Program
- Heating (Temperature Rise):
Usually controlled by the programmed settings.- Maximum heating rate: 100 °C/min
- In the early stage of an experiment, if rapid heating is required, the heating mode can be switched to manual.
- Slowly turn the power knob clockwise to gradually increase the current and raise the temperature.
- Typically, below 200 °C, manual heating is recommended, otherwise temperature control may be inaccurate.
- Between 1000 °C and 2000 °C, infrared automatic temperature control can be used.
- Heating must be performed under vacuum.
- Monitor the current meter; do not allow the secondary rated current to exceed 700 A.
- Cooling:
The cooling process can be programmed, or heating can simply be turned off to let the furnace cool naturally. Note:- During cooling, do not stop water circulation, otherwise the furnace sealing ring may be damaged.
(2) Setting the Pressurizing Program
- Pre-pressurization:
- Performed before heating.
- Typical pressure range: 1.0–1.5 MPa
- Pre-pressurizing can be done manually.
- Pressurization:
- When the temperature reaches the set value, pressure is applied to the sample.
- This process is usually carried out automatically via programmed control.
