How to set up heating and pressurizing scheme in vacuum furnace?

Heating and pressure procedure of vacuum furnace setting:
(1) Set heating program: generally set according to the program, and the high temperature rise rate is 100 ℃ / min. if you want to rapidly increase the temperature rise at the beginning of the test, you can put the temperature rise mode in the “manual” gear. Slowly adjust the clockwise power to slowly increase the current;
Generally, the temperature can be raised manually at a temperature lower than 200 ℃, otherwise, temperature control is not allowed. In the range of 1000 ~ 2000 ℃, the temperature of the furnace is automatically controlled by infrared.

Note: heating must be carried out in vacuum: note that the indication of current meter shall not exceed the secondary rated current 700a. Cooling can be programmed, or heating can be turned off directly, so that it can cool down by itself.
Note: when the water is not allowed to stop during the cooling process, the sealing ring of the furnace body will burn out.

(2) Set up the boost procedure.
1. Preload: preload before heating, usually in the range of 1.0-1.5mpa; preload can be realized manually.
2. Pressurization: after the temperature is raised to the predetermined temperature, pressurize the sample. This routine is usually set to automatically pressurize the sample.
