Use Yudian program temperature control instrument (standard)
1. 30-segment program temperature control intelligent PID adjustment.
2. With over-temperature protection, the electric furnace heating circuit will be automatically cut off when the temperature is over-temperature or when the couple is broken. ON, 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 with optional 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
(replacement of imported instruments requires additional payment and purchase)

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 plug-in valve, a non-mechanical pressure gauge and a KF-25 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 reach below 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, its measurement range is 3.8x10-5 to 1125Torr. No coefficient conversion is required for different types of measurement gases.

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.
3. Option one:
At the top of the flange is installed an electromagnet sample hanging device that can withstand a maximum of 1000g. As shown in Figure 1, the sample is hung on the hook through the hanging wire. Drop into the quenching box together, 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. Fig. 4 is a suspension wire.

4. Option two:
A quartz rod with a gondola is worn from the middle of the upper flange, and the gondola is filled with materials. The three temperature zones can be set to different temperatures, and the material can be quenched in different temperature zones by moving the quartz rod up and down. The quartz rod is long enough to put the contents of the gondola into the quenching liquid box.

Precautions
1. The air pressure in the furnace tube cannot be higher than 0.02MPa
2. Due to the high internal pressure of the gas cylinder, when introducing gas into the furnace tube, a pressure reducing valve must be installed on the gas cylinder. To ensure safety, it is recommended to use a pressure lower than 0.02MPa.
3. When the furnace tube used is corundum tube, when the furnace temperature is higher than 1500 ° C, the furnace tube cannot be in a vacuum state, and the pressure in the furnace tube must be equal to the atmospheric pressure.
4. The gas flow entering the furnace tube needs to be less than 200SCCM to avoid the impact of the cold air flow on the hot furnace tube.
5. For the experiment of sample heating, it is not recommended to close the suction valve and inlet valve of the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you must always pay attention to the indication of the pressure gauge. If the air pressure is greater than 0.02MPa, the exhaust valve must be opened immediately to prevent accidents (such as furnace tube rupture, flange flying out, etc.)
6. Do not use graphite crucibles in alumina tubes.
