Self introduction of long bar heat treatment machine !
Principle of induction heating long bar heat treatment machine: the workpiece is placed in the inductor, the inductor is generally input intermediate frequency alternating current (1000-300000Hz or higher) hollow copper tube. It is induction current of the same frequency, which is produced by alternating magnetic field in the workpiece. The distribution of the induction current in the workpiece is uneven. It will be strong on the surface and weak inside, close to 0 at the center. Using this skin effect, the surface of the workpiece can be heated rapidly, and the surface temperature rises to 800-1000ºC in a few seconds, while the center temperature of the workpiece is very small.
The advantages of steel tube induction heating and quenching and tempering equipment are:
1. Adopting the world-famous German Siemens IGBT power devices and unique inverter technology, 100% load persistence rate design, maximum power for 24 hours operation, high reliability guarantee.
2. The automatic control type can adjust heating time, heating power, holding time, holding power and cooling time; greatly improve the quality of heating products and heating repeatability, simplify the operation technology of workers.
3. Light weight, small size, simple installation, connected to 380V three-phase power supply.
4.The long bar heat treatment machine occupies a very small area, simple operation and can learn in a few minutes.
5.Special safety, the output voltage is below 36V, avoid high voltage electric shock risk.
6. The heating efficiency is as high as 90%. The energy consumption is only 20%-30% of the high frequency of the old electronic tube. There is almost no electricity in standby state, and it can work continuously for 24 hours.
7.The inductor can be freely disassembled and replaced quickly. Ultra fast heating greatly reduces the oxidation deformation of the workpiece.
8. Replacing oxygen, acetylene, coal and other dangerous heating methods, induction heating is more safe.
9. The induction heating equipment has perfect automatic protection functions such as over-current, over-voltage, over-temperature, water shortage, phase absence, water temperature, water pressure, voltage limiting, current limiting, starting over-current and constant current, and is equipped with fault self-diagnosis alarm system.
10. The equipment has the control function of constant current and constant power, greatly optimizes the heating process of metal, realizes high-efficiency and rapid heating, and fully displays the superior performance of the product.
