Intelligent high-temperature tube furnace

Intelligent high-temperature tube furnaceIntroduction:
The tubular high-temperature resistance furnace uses resistance wire as the heating element, adopts a double-layer shell structure and an intelligent program temperature control system, controlled by thyristor, with high temperature control accuracy; The double-layer furnace shell is equipped with an air cooling system to reduce the surface temperature of the furnace shell; The furnace cover can be opened, quickly cooling down, with a reasonable structure and beautiful appearance. Suitable for high temperature atmosphere sintering, atmosphere reduction, CVD experiments, vacuum annealing, etc. in universities, research institutes, and industrial and mining enterprises.
　　Main uses and scope of application of tubular electric furnace:Used for graphene growth, high-temperature atmosphere sintering, atmosphere reduction, CVD experiments, etc. in universities, research institutes, and industrial and mining enterprises.
　　Intelligent high-temperature tube furnaceUsage:
Normal operation: Connect the power and press the ↑ key for two seconds to pause the SV window. Setting steps: Press the ← key to display C01 on PV. Press ←↑↓ to set the desired temperature. Press the SET key, and the PV will display T01. Press ←↑↓ to set -1. Wait until the menu returns (SV displays STOP). Press the ↓ key again for two seconds, and the SV will display RUN. At this point, the PV displays a temperature increase. The SV window HOLD and the set temperature are displayed alternately.
Programmable operation method: Connect the power, turn on the circulation fan switch behind the instrument, and press the ↑ key for two seconds to make the SV window appear STOP (pause). Setting steps: Press the ← key, and the upper row PV will display C01, indicating the starting temperature that needs to be programmed. Operate the ←↑↓ keys to make the lower row SV reach the desired starting temperature. Press the SET key again, and the PV will display T01, indicating the time it takes for the starting temperature to reach the lower set temperature. Press the ←↑↓ keys to make the SV reach the desired time. Press the SET button again, and PV will display C02, indicating the starting temperature C01 that was just set. It took T01 time to reach the desired temperature. Press ←↑↓ to make SV reach the desired temperature. If constant temperature is required, C01 and C02 should be set to the same value. Press the SET button again, and the PV will display T02 indicating the time set from C02 to the lower temperature. Follow the previous steps... and set the T parameter to "-121" in the later stage to automatically shut down for up to 30 stages. After the txx setting in the later stage is completed, wait for SV to return to STOP and then press the ↓ button to display the RUN window. The instrument will automatically start working according to the set program. The programming adopts the temperature time temperature format, which is defined as setting the temperature from the current segment and reaching the temperature after the set time in that segment.
　　Precautions for using a tubular high-temperature electric furnace:
When using a tubular electric furnace, it is important to control the heating and cooling rate at 5 degrees per minute, the slower the better. Rapid cooling and heating are the main causes of pipe breakage.
2. Always keep the inside of the tube clean and do not leave any samples in the tube to avoid chemical reactions that may cause cracking of the corundum tube. I suggest you place the test sample in a crucible and put it into a tube.
3. When setting out and sampling, it is best to keep within 200 degrees and slowly advance from the edge to the center. The main reason for the fracture of corundum tubes during high-temperature sample delivery and sampling.
4. It is necessary to place the mullite furnace plug on both sides of the tubular electric furnace tube to avoid thermal radiation damage to the silicone ring inside the flange. The crucible should be placed in the middle of the tube of the tubular electric furnace.
Characteristics of high-temperature tube furnace:

1. Control accuracy: ± 1 ℃ Furnace temperature uniformity: ± 1 ℃ (depending on the size of the heating chamber).
2. The furnace tube adopts quartz glass tube.
3. Stainless steel metal flange seal (double rubber ring)
4. The furnace body is finely coated with corrosion-resistant and acid alkali resistant materials, and is isolated from the furnace by air-cooled furnace walls with temperatures close to room temperature
5. Dual circuit protection (over temperature, over pressure, over current, section coupling, power outage, etc.)
6. Imported refractory materials with good insulation performance and high temperature resistance
7. Vacuum gauge vacuum degree 0 to negative 0.1Mpa
8. Electric furnaces can carry various gases (oxygen, nitrogen, argon, hydrogen, etc.)
9. Temperature category: 800 ℃, 1000 ℃, 1200 ℃, three types
10. Using reliable integrated circuits, the working environment is good, anti-interference, and the temperature of the furnace shell is ≤ 50 ℃ at high temperatures, greatly improving the working environment. Microcomputer program control, programmable 2 sets of 16 segment curves, automatic heating/cooling, temperature control parameters and programs can be modified during operation, flexible and convenient, and easy to operate. Temperature control accuracy: ± 1 ℃ Temperature control accuracy: ± 1 ℃. The heating rate is fast, with a fast heating rate of ≤ 5/min. The furnace material department is made of imported Morgan fiber, which has high operating temperature, small heat storage capacity, and good insulation performance (energy-saving fruit is more than 80% of old-fashioned electric furnaces). Reasonable structure, double-layer inner and outer furnace sleeves, air-cooled heat dissipation, can greatly shorten the test cycle.
