Control mode 

 Use Yudian program temperature control instrument (standard)

1. 50-segment program temperature control intelligent PID adjustment.

2. With over-temperature protection. The electric furnace heating circuit is automatically cut off when over-temperature protection or over-temperature protection occurs. (When the temperature of the electric furnace exceeds 1720 degrees or the thermocouple is blown, the AC relay on the main circuit will be automatically disconnected, the main circuit is disconnected, the ON light on the panel is off, the OFF light is on, and the electric furnace is limitedly protected).

3. With 485 communication interface (standard configuration when purchasing software).

4. It has a power failure protection function, that is, when the furnace is powered on after the power is turned off, the program does not start from the initial temperature, but starts from the furnace temperature when the power is turned off.

5. The meter has the function of temperature self-tuning.

Vacuum seal flange and valve

1. A stainless steel sealing flange and stainless steel needle valve are installed on the top of the furnace body.

2. A bottom plate valve, a non-mechanical pressure gauge, and a KF25 vacuum interface are used to connect the vacuum pump at the bottom of the furnace body.

3. Vacuum degree: The vacuum degree of the mechanical pump can be less than 1Pa. If you want to obtain a higher vacuum degree, you can choose a domestic or imported high vacuum unit. The vacuum degree can reach 10-3Pa.

Optional: The following accessories increase vacuum efficiency.

4. KF25 stainless steel bellows, KF25 quick remover clamp.

5. Optional anti-corrosion digital vacuum gauge with a measurement range of 3.8x10-5 to 1125 Torr. No coefficient conversion is required due to different types of measurement gases.

6. At the top of the flange is installed an electromagnet sample hanging device that can withstand a maximum of 500g. As shown in Figure 1, the sample is hung on the hook through the hanging wire, as shown in Figure 2. Click the control button of the sample hanging device of the electromagnet. The hanging wires fall together into the quenching box, as shown in Figure 3. Before releasing the sample, 5 PSI of argon must be flushed in and the manual flapper valve at the bottom of the furnace tube opened. Pic 4 is the hanging wire

Quenching container

1. A stainless steel box for holding the quenching liquid is fixed at the bottom of the furnace tube.

2. A large manual plug valve is installed between the bottom of the furnace tube and the liquid box.
