Principle of ultrasonic induction heating: the workpiece is placed in the inductor. The inductor is generally a hollow copper tube that inputs medium frequency or high frequency AC (1000-300000 Hz or higher). The generation of alternating magnetic field produces induced current of the same frequency in the workpiece. The distribution of this induced current in the workpiece is uneven. It is strong on the surface, but weak inside, and close to 0 to the heart. Using this skin effect, the workpiece surface can be heated rapidly, and the surface temperature rises to 800-1000 º C in a few seconds, while the temperature rise in the heart is very small.
Advantages of ultra audio induction heating:
1. It adopts internationally famous Siemens IGBT power device and unique inverter technology, 100% load duration design, 24-hour operation under maximum power and high reliability guarantee.
2. Automatic control type can adjust heating time, heating power, holding time, holding power and cooling time; The quality of heating products and the repeatability of heating are greatly improved, and the operation technology of workers is simplified.
3. Especially safe, the output voltage is lower than 36V, avoiding the risk of high voltage electric shock.
4. Small footprint and simple operation.
5. Light weight, small volume and simple installation.
6. The latest environmental protection products that replace the heating of dangerous goods such as oxygen, acetylene and coal are safer and safer without open fire.
7. The inductor can be disassembled and replaced freely and quickly, and the ultra fast heating greatly reduces the oxidation deformation of the workpiece.
8. The heating efficiency is more than 90%, and the energy consumption is only 20% - 30% of the high frequency of the old electronic tube. There is almost no electricity in standby mode, and it can work continuously for 24 hours.
9. It has perfect automatic protection functions such as over-current, over-voltage, over temperature, water shortage and shortage, and is equipped with fault self diagnosis alarm system.
10. It has the control function of constant current and constant power, which greatly optimizes the metal heating process, realizes efficient and rapid heating, and gives full play to the superior performance of the product.
