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.

Guarantee period
|
One year warranty, lifetime technical support
Special Note:
1. Consumable parts such as heating elements, furnace tubes, sample crucibles, etc. are not under warranty.
2. Damage caused by the use of corrosive gases and acid gases is not covered by the warranty.

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. In order to ensure safety, it is recommended to use a pressure lower than 0.02 MPa.
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 into 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.
7. MoSi2 heating element should not be used at low temperature (400 ℃ -700 ℃) for a long time, otherwise the heating element may be damaged.
8. The sample is fixed on a suspension hook at the bottom of the flange by a high temperature resistant wire. (Remarks: The maximum use temperature of the wire that is standard with the equipment of our company is 1200 degrees. If the customer's use temperature is above 1200 degrees, you can buy our company's special high temperature resistant wire, please contact us for details)
