Air inlet and outlet system

control system

1.  Sintering process curve setting: dynamically display the setting curve,  the equipment sintering can pre store multiple process curves, and each  process curve can be freely set;
2. Can schedule sintering and achieve unmanned sintering process curve sintering;
3.  Real time display of sintering power and voltage information, recording  sintering data, and export to achieve paperless recording;
4. Capable of remote control and real-time observation of equipment status;
5.  Temperature correction: The difference between the main control  temperature and the sample temperature is corrected nonlinearly  throughout the sintering process

You can log in to the control system anytime and anywhere through computers, mobile phones, and other terminals to view the operating status of the heating furnace (temperature, pressure, heating rate, etc.), and remotely adjust parameters and start/pause programs according to experimental needs. No need to travel back and forth to the laboratory at night or on holidays to meet the parameter tuning needs during the experimental process; Real time monitoring of key experimental processes can also be achieved during cross regional business trips, significantly reducing ineffective commuting time and allowing researchers to allocate work energy more efficiently.

Temperature accuracy

±1℃

Heating element

MoDopedFe-Cr-Alalloy

Pressure measurement and monitoring

Using  a mechanical pressure gauge, the outer shell of the gauge is an  airtight structure, which can effectively protect the internal  components from environmental impact and debris intrusion, and has  strong corrosion and high temperature resistance.

Gas supply system

The  gas flow rate is controlled by a float flowmeter, integrated with the  equipment, and leak testing has been carried out before leaving the  factory.

Equipment usage precautions

1. When the furnace temperature of the equipment is ≥ 300 ℃, it is prohibited to open the furnace to avoid injury;
2.  When using the equipment, the pressure inside the furnace tube should  not exceed 0.125MPa (absolute pressure) to prevent equipment damage  caused by excessive pressure;
3. When used under vacuum, the operating temperature of the equipment shall not exceed 800 ℃.
4.  The internal pressure of the gas supply steel cylinder is relatively  high. When gas is introduced into the furnace tube, a pressure reducing  valve must be installed on the cylinder. It is recommended to purchase a  small pressure reducing valve for testing, with a range of  0.01MPa-0.15MPa, which will be more precise and safe to use.
5. When  the temperature of the furnace body exceeds 1000 ℃, the furnace tube  cannot be in a vacuum state, and the air pressure inside the furnace  tube must be equivalent to atmospheric pressure and maintained at  atmospheric pressure;
6. Long term use temperature of high-purity quartz tube ≤ 1100 ℃
7.  It is not recommended to close the exhaust valve and intake valve at  the flange end of the furnace tube during heating experiments. If it is  necessary to close the gas valve to heat the sample, it is necessary to  always pay attention to the reading on the pressure gauge. The absolute  pressure gauge reading should not exceed 0.15MPa. The exhaust end valve  must be immediately opened to prevent accidents (such as furnace tube  rupture, flange flying out, etc.).
