In These series machines, series oscillating circuit is applied, through high frequency transformer, low voltage and high current power is output to go through the induction coil. Quenching – The quench process is just as important as the heating process with induction hardening. Frequencies in the range of 100 to 450 kHz create comparatively high energy heat that is suitable for rapid heating of small objects, or the skin of large parts. It is also electric energy heating, which can save 40% of electricity compared to traditional furnaces, electric ovens, etc. Heating power, retaining power, heating time, retaining time can be preset and adjusted, this makes it possible to control the heating curve and heating time. Carbide saw blade size teeth welding. Feature: Automation. High frequency induction hardening is a type of surface heating used for hardening depths from 0.
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. Super audio induction heating equipment, that is, induction heating the workpiece, to carry out the surface hardening equipment. Induction hardening is excellent at repairing warranty claims / field failures. Not all parts have a high risk of cracking, but part characteristics such as internal holes, sharp edges, and certain higher carbon materials will require more consideration. The massive circulating current in the work coil is kept out of the ferrite transformer greatly reducing cooling problems.
Like many other forms of heat treatment, it can take years to develop the knowledge and skills to gain expertise in induction hardening. Therefore it is useful to combine all of these losses into a single "loss resistance. " The passage of current through this coil generates a very intense and rapidly changing magnetic field in the space within the work coil. Secondly, Soft switching technology is used in SPG50K voltage regulate circuit, this also improve the reliability very much. Manufacturing Level: E. - Packing: Plywood and Steel Frame More. High Frequency silver brazing for small fine metal joints. The vertical purple line marks the other end of the capacitive load region, where the inverter load current transitions again to lagging "Inductive" load current.
To evaluate which solution best suits your production needs, please contact us! Frequency Range: High Frequency. Output current: 200 - 600 A. The inductor can be quickly disassembled and replaced freely, and ultra-fast heating greatly reduces the oxidation deformation of the workpiece. The inverter in this demonstration prototype was a simple half-bridge consisting of two MTW14N50 MOSFETs made my On-semiconductor (formerly Motorola. )
These are known as eddy currents. Transformer - L510×W255×H400. Manufacturers Profiles/Analysis. Therefore the only part of the matching network that is available to adjust is the inductor. This is particularly true in high power applications where the devices may already be running close to maximum switching speeds. This significantly reduces turn-on switching losses due to device output capacitance in MOSFETs operated at high voltages. For this reason the situation described for the previous photograph is preferable to being precisely in tune. Single Shot – Single shot hardening is the most common method of induction hardening where the part and coil remain in the same spot during the heating process. This means that the inverter always sees a load current that is either in-phase or at worst slightly lagging in power factor. The industrial chiller realizes cooling by using a compressor.
6. Who are the distributors, dealers, and traders of high frequency induction heating machinemarket? There are many arguments for keeping the size of the DC bus capacitor down to a minimum. Induction heating can be used for any application where we want to heat an electrically conductive material in a clean, efficient and controlled manner. It must also carry the full current carried by the work coil, although this is typically not a problem in low power applications. In these three series machines, the high frequency transformer is separated from the generator, with 2 meters connecting cable at least.
Packing: Angle Iron Frame and Human Made Wooden Sheet Box. The worst thing that can happen is that the tank circuit becomes detuned such that its natural resonant frequency is just above the operating frequency of the inverter. By utilizing two different frequencies, it is possible to contour the hardening pattern more effectively on gear-like components, which further improves the strength of the part. For example, an impedance matching network is often required between the High Frequency source and the work coil in order to ensure good power transfer. When operating a high-frequency heater, the metal that requires heat treatment will be placed in the high-frequency coil, and the magnetic beam mentioned above will penetrate the entire ready-to-be-heated metal object. Induction processing is performed one part at a time allowing for very predictable dimensional movement from part to part.
Therefore leakage inductance in the transformer is not as damaging to performance as inter-winding capacitance. The equipment has the control function of constant current and constant power, which greatly optimizes the heating process of metal, realizes efficient and fast heating, and gives full play to the superior performance of products. Direct connection of such a voltage source to a parallel resonant circuit would cause excessive currents to flow at all harmonics of the drive frequency! Structure: Wall-Mounted. Workpieces are usually treated individually. We excel with our after-sales services. The reason for this is that any leakage inductance exhibited by a transformer located in this position merely adds to the matching inductance at the input to the L-match circuit. Metal hardening of ammunition, gear teeth, saw blades and drive shafts, etc are also common applications because the induction process heats the surface of the metal very rapidly. The electrical frequency influences the process of induction heating. Note the large surface area of the connection plates on the Celem conduction-cooled components and the reactive power rating (KVAR) printed on the rating label. The degree of power control achieveable by altering the matching inductor is moderate.
Finally stray inductance must be kept to an absolute minimum so that the capacitor appears as a lumped circuit element compared to the reasonably low inductance of the work coil it is connected to. At still higher powers it is possible to use several seperate inverters effectively connected in parallel to meet the high load-current demands. Including Parts: Generator, Induction Coils, Foot Switch.
