It is also electric energy heating, which can save 40% of electricity compared to traditional furnaces, electric ovens, etc. The principle of ultra high frequency induction heating equipment: the workpiece is placed into an induction coil, which is a generally a hollow copper pipe with the input of medium frequency or high frequency AC. Heat Transfer Surface: Induction Heating. Small volume, simple operation, a few minutes to learn. Therefore if precise power control is required the actual induction heating power must be measured, compared to the requested "power setting" from the operator and an error signal fed back to continually adjust the DC link voltage in a closed-loop fashion to minimise the error. The resonant peaks become less tall, and broader as the Q factor falls. This magnetic field generates a flow of current in the work piece. What is Induction Heating used for? Some users have been used for very 10year but still work in good conditions. For this reason the situation described for the previous photograph is preferable to being precisely in tune. Of course, if you'd rather work by e-mail, fax, or phone, our contact page gives you all that information, too. As the operating frequency of the inverter is moved away from the resonant frquency of the tank circuit, there is less resonant rise in the tank circuit, and the current in the work coil diminishes.

High Frequency Induction Hardening Machine For Plants
Single piece flow – Because induction hardening is not a batch process (typically one part is hardened at a time), induction machines can be placed in a manufacturing cell, allowing the process flow to be uninterrupted. To avoid blocking the cooling pipes, if a water pump is used for water supply, install filter cooling water at the water pump inlet. Market Segment By Applications: Heating (Hot Forging, Annealing (Tempering and Modulation), Heat Treatment (Surface Quench), Silver Soldering and Brazing), Hot Fitting and Smelting) and Welding (Braze Welding. Since induction heating is a non-contact process it can be used to heat the getter that is already sealed inside a vessel. How does Induction Heating work? What is required for Induction Heating? Work coils using this technique often consist of only a few turns of a thick copper conductor but with large currents of many hundreds or thousands of amps flowing. This causes tremendous currents to flow through the workpiece. Color: Blue and Black More. Most specifications will require surface hardness measurements along with effective case depths to determine the depth of hardening. However, the basic principle of operation of any induction heater remains the same as described earlier. Digital Control Panel. Ultra-high Frequency Induction Heating Machine Features: Ultra-high frequency induction heating equipment has such features as high frequency (the minimum heated welding diameter is 0. Where is induction hardening used?
This causes a forced reverse recovery of the free-wheel diodes whilst they are already carrying significant forward current. Welding Range: Metal Products. Usage: Sand Casting. Output current: 200 - 600 A. Simply go to our "request a quote" page and fill out the short web form, like Product Name (High Frequency Induction Heating Machine), Product Description. The GREEN traces represent the current passing through the matching inductor, and therefore the load current seen by the inverter.
Produce alternating magnetic field in the workpiece to produce the same frequency induction current, the distribution of the induction current in the workpiece is not uniform, strong on the surface, and in the interior is very weak, close to the core, using the skin effect, can make the workpiece surface heating rapidly, in a few seconds the surface temperature rises to 800-1000 degree, while the workpiece core temperature increases very little. Dongguan DaWei, eldec, Shenzhen Shuangping, HF Energy, Baoding Hong, GH Group, Dai-ich High Frequency, Satra International, Tianjin Tiangao, President Honor Industries, Denki Kogyo, Taizhou Hongri, Ajax Tocco, Inductm Group, SPC Electronics and EFD Induction. Applications: Hardening, Quenching, Brazing, Welding etc. At this frequency current through the work coil is also maximum and the largest heating effect is developed at this frequency.
What Is Induction Hardening
The targeted temperature for induction temper is higher than that of furnace tempering due to the decreased temper time. This results in a large current surge through both the diode and the opposing MOSFET that is turning on. Structure: Wall-Mounted. It has automatic and manual welding functions, and its operation is simple and practical. Max Temperature: 900°c. How does high frequency induction hardening differ from medium and low frequency hardening? Varying the duty ratio of the devices in the inverter.
Ultrahigh frequency induction brazing machine is suitable for welding thin wall pipes. Use coaxial cables and split-type induction rings to welded at the scene away from the power supply. Types of Induction Heating Equipment. This argument for closed-loop power control also applies to all of the methods that follow below. To evaluate which solution best suits your production needs, please contact us! This situation is undesirable because the load current seen by the inverter changes direction before the applied voltage changes. However, it should be realised that proper control of the inverter operating frequency should ensure that it tracks the resonant frequency of the tank circuit. Protection Function. Due to the adopting of our third generation inverting control technology, These machines are acterized not only with high power and high frequency, but also with high reliability on the condition of normal IGBT module.
High Frequency Induction Hardening Machine Price
This is needed to remove excess heat generated by the passage of the large high frequency current through the work coil and its associated tank capacitor. In order to heat a solid piece of metal via induction heating we need to cause a TREMENDOUS current to flow in the surface of the metal.
Each of the distributed inverters is connected to the remote work coil via its own pair of matching inductors which ensure that the total load is spread evenly among all of the inverters. If we look at the inverter load current phase (bottom green plot) we can see that this is always between 0 degrees and -90 degrees when it crosses the white line no matter how abruptly or slowly it slews. These occur because the mid-point of the bridge leg has not been fully commutated to the opposite supply rail during the dead-time before the next MOSFET turns on. Scanning is frequently used to harden shafts because heating the entire shaft at once would require too much power. US$ 1400-1480 / Set.
Therefore the only part of the matching network that is available to adjust is the inductor. This later point becoming very important in high-powered systems. This plot shows the importance of accurate tuning in an induction heating application. At still higher powers it is possible to use several seperate inverters effectively connected in parallel to meet the high load-current demands. Manufacturer/Factory. The non contact nature of induction heating also means that it can be used to heat materials in analytical applications without risk of contaminating the specimen. Although the tank capacitor current is in-phase with the inverter output this current can be many hundreds of amps making closed-core ferrite CTs impractical. 4, Durable time is very long. It is impossible to not distort the part with induction hardening due to the phase changes in the metal.
High Frequency Induction Hardening Machine For Concrete
Type: Plastic Welders More. When the device needs to be repaired or maintained, it must be repaired after the power is off. At frequencies above the natural resonant frequency of the LCLR work coil arrangement the inductive reactance of the matching network dominates and the inverter's load current lags the applied voltage. The result is that the getter absorbs any last remaining traces of gas inside the vacuum tube and increases the purity of the vacuum. From the bottom graph we can also see that the load current from the inverter exhibits not one but two abrupt phase changes as the operating frequency is progressively increased.
Certification: ISO9001. Besides analysis and scenarios, we provide insights into global, regional, and country-level information and data, to ensure nothing remains hidden in any target market. Item: Cookware Brazing Machine. The L-match network between the inverter and the tank circuit technically consists of an inductive and a capacitive part.
The comparatively low currents make the inverter less sensitive to layout issues and stray inductance. Automatic Grade: Automatic. Add comments here about water cooling#. We can now label some areas of interest on the bode plot diagram below. Induction heating is effective due to the internal generation of heat within the work piece. Dimension: L580×W250×H500.
Heating time: 1-99 s (auto). When the cap is removed, the foil remains providing an airtight seal and preventing any tampering or contamination of the bottle's contents until the customer pierces the foil. After-sales Service: Within 24 Hours Response. This coil is known as the work coil. High efficiency and energy saving. The alternating current in the coil induces an alternating magnetic field within the work piece which causes the outer surface of the part to heat to a temperature above the transformation range. Full-wave rectified (but un-smoothed) mains can work as well as smoothed and regulated DC when it comes to heating metal, but peak currents are higher for the same average heating power. As the operating frequency is increased above the maximum power point, the voltage across the work coil decreases and less heating effect is generated in the workpiece.
