Performance and application range analysis of high-temperature annealing furnace

The vacuum magnetic field heating system of the high-temperature annealing furnace is a feedback regulation heating system composed of a high-temperature furnace, a high-temperature furnace heating power supply, LabVIEW control software, an electromagnet, a precision bipolar constant temperature power supply, a molecular pump, and a water-cooling device.
Temperature control: The required temperature value is directly set through the human-computer interaction interface on the software, and the computer software processes the instructions to the heating controller of the high-temperature furnace. The controller reads the actual temperature value of the sample area through a temperature sensor (thermocouple) and adjusts the output current through its internal fuzzy control PID. Generally speaking, the temperature is stable within its accuracy range to achieve the different temperatures required by the user.
Magnetic field control: Users can directly set the required magnetic field size through the software, read the actual magnetic field value through the precision Gauss meter, and then feedback the actual read magnetic field value to the precision constant current power supply. After being processed by the internal software of the power supply, users can directly control the output current of the precision constant current power supply, thereby achieving the magnetic field required by the user and displaying it in real-time on the software.
Vacuum environment: The vacuum environment is obtained through a molecular pump group, displayed and monitored by a high vacuum full range vacuum gauge, and the detection results are transmitted in real-time to the computer.
Annealing process: Heat the sample in a strong magnetic field (or non-magnetic) environment, heat it to a certain temperature (user needs to set it by themselves) and maintain that temperature, then continue to add the magnetic field (can be changed at any time), achieve the user's goal, turn off the magnetic field, turn off the heating environment, and cool it to room temperature.
Sample environment: This high-temperature annealing furnace can simultaneously place the tested sample in a strong magnetic field, high vacuum, and high temperature environment. Meanwhile, these three experimental environments can also be individually or arbitrarily combined to meet the testing requirements of different samples in different environments.
The high-temperature magnetic field heating furnace system is a mechanical pump (dry pump) in the molecular pump group that first roughens the vacuum chamber (sample chamber). When the maximum vacuum of the molecular pump is reached, turn on the molecular pump for high vacuum extraction to achieve the desired vacuum for the customer. Open the software and input the required magnetic field and temperature values. Through closed-loop feedback adjustment, the temperature of the sample in the device is automatically controlled and stabilized at a certain temperature value. The software can complete experiments according to the experimental conditions provided by the user.
The scope of application of high-temperature annealing furnace: various soft magnetic materials that require heating or demagnetization in high temperature, high vacuum, and strong magnetic field environments.
