What are the commonly used sensing heating equipment?

Time:2022-09-13

We only know that induction heating equipment is divided into: high frequency, medium frequency, ultra -high frequency, ultra -audio, etc. The main application areas of induction heating equipment are the preheating, thermal treatment, welding, and melting of metal devices in the metal industry. Essence In addition, induction heating techniques in processing paint, bonding, and semiconductor are also widely used. So, what are the commonly used sensing heating equipment? Xiaobian revealed for you.


1. Simulation control sensing heating equipment

The main control circuit is controlled by analog circuit, 0 ~ 5V power adjustment. The disadvantages of such equipment: poor temperature control accuracy, poor IGBT over zero control, core power component power consumption is large, easy to damage, the main circuit often changes with the workpiece, the equipment does not work in the resonant state, and the output efficiency is low. It is only used in the occasion of low heating temperature and has gradually been eliminated in society.


Second, intelligent sensing heating equipment

The new generation of intelligent sensing heating equipment: digital circuit control, high temperature control accuracy, excessive accuracy of IGBT under switching, automatic tracking of the main circuit resonance frequency, and adjusting the load to ensure that the circuit is in a resonant state according to the changes in the workpiece, so that the entire whole The output efficiency of the device is extremely high.


The intelligent sensing heating equipment has the following characteristics:

1. Control core part: Generally, the world's most advanced high -speed digital signal processor (HDSP) is used, and special chips are used as auxiliary processors.

2. The inverter device generally adopts efficient and fast resonance control method. The inverter efficiency is greater than 95%, and the host power factor is greater than 0.9.

3. The equipment adopts a design structure combined with cold and water -cooled.

4. Control method: full digital, efficient and fast resonance, which can adapt to sensors of various parameters. Smart device power supply generally built -in digital PID temperature control module

piece.

5. Bring IO interface: simulation output, analog quantity input, IO output and IO input interface, RS232 or RS485 communication interface.

6. The communication interface can be connected to the special data recorder.

7. Power adjustment adjustment method: Schedule adjustment, 0%~ 100%adjustable, resolution uses 0.1%or 0.01%level, and the output stability can reach 0.3%or 0.025%.


Third, inductive melting equipment series

Application: It is mainly used for melting steel, iron, copper, aluminum and alloy, etc. It has the characteristics of high melting efficiency, good power -saving effect, uniform metal components, less burning, fast temperature, and easy control. occasion.

feature:

1. Constant power output, the faster the melting speed, the more obvious the power saving effect.

2. Starting zero -voltage frequency sweeping software can better meet the requirements of frequent startup.

3. Comprehensive protection measures such as overcurrent, overvoltage, current limit, pressure limit, water dehydration, deficiency protection, etc., so that the equipment is reliable to run on the premise of ensuring the melting speed.

4. Simple operation, suitable for various casting processes.
