High and medium frequency induction heating equipment is widely used in modern industrial production, and its fast and efficient heating method has become an important technology in the field of metal heat treatment. This article will delve into the working principle of ** high and medium frequency induction heating equipment and the load system, the article is for reference only:
How it works.
The working principle of high and medium frequency induction heating equipment is mainly divided into the following steps:
Power supply: Through the three-phase uncontrolled rectifier bridge and filter circuit, the three-phase 380V 50Hz alternating current is converted into a DC voltage source.
DC filtering: The obtained DC power is filtered to ensure the stability of the power supply.
Inverter circuit: A single-phase inverter circuit is used to convert the filtered direct current into single-phase alternating current for supply to the load system.
This process ensures efficient and controllable power transfer from the power supply to the load system.
Load system in detail.
A load system is an inductor-workpiece system in which an inductor is a coil wound from a hollow water-cooled copper tube fed through superaudio or high-frequency alternating current. The workpiece is placed in the high-frequency heating inductor, the workpiece is placed in the alternating magnetic field, and the eddy current loss is generated by the electromagnetic induction principle to heat the workpiece.
Sensor Features:
High-frequency sensor design: Ultrasound or high-frequency alternating current is used to make heating faster.
Cooling Copper Tubes: Hollow water cooling copper tubes ensure that the inductor does not overheat during high-frequency operation, extending its service life.
Load System Advantages:
Fast heating speed: The vortex heating method is used to heat faster than the conduction method.
Efficient energy utilization: Electromagnetic induction heating has high efficiency and low energy concentration loss, which makes the whole heating process more energy-saving.
Controllable: By adjusting parameters such as current frequency, power and sensor shape, precise control of the heating zone can be achieved to ensure the ideal heating layer depth.
Diversified heating needs: It is suitable for a variety of heating needs such as medium frequency smelting, round steel diathermy, high frequency quenching, motor hot assembly and hot disassembly, interference assembly, annealing, tempering, round steel ** medium frequency quenching and tempering production line.
Load System Customization:
Depending on the user's induction heating needs, the load system has different forms and characteristics. Factors such as the shape, size, and material of the specific heating workpiece will affect the design of the load system, so it needs to be customized to ensure the best heating effect.
Development prospects. With the continuous development of industrial technology, the application prospect of high and medium frequency induction heating equipment in the field of metal heat treatment is becoming more and more broad. Its high efficiency and energy saving characteristics make it an indispensable part of modern industrial production. In the future, with the continuous innovation of science and technology, it is believed that high and medium frequency induction heating equipment will show strong application value in more fields and promote the continuous progress of industrial production.
