High Frequency Induction Hardening Machine

This refers to the electronics that sits between the source of high frequency power and the work coil we are using for heating. It is impossible to not distort the part with induction hardening due to the phase changes in the metal. Therefore the only part of the matching network that is available to adjust is the inductor. Induction hardening uses induced heat and rapid cooling (quenching) to increase the hardness and durability of steel. My hope is that it will give you enough familiarity with the process to become more comfortable engaging in a conversation about induction hardening. Induction hardening boosts throughput. 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. The power setting of this type of induction heater can be controlled in a number of different ways: 1. Dongguan Guangyuan Inverter Electronic Equipment Factory. This significantly reduces turn-on switching losses due to device output capacitance in MOSFETs operated at high voltages. If both legs of the H-bridge can be controlled independently then there is scope for controlling power throughput using phase-shift control. Supply (Production), Consumption, Export, Import by Region. In practice both of these functions are usually accomplished by a single purpose built power capacitor.

However, the seperate inverters are not directly tied in parallel at the output terminals of their H-bridges. Selective hardening – Induction allows you to harden only the desired portion of a part, whereas most furnace-based heat treat processes treat the entire component. What are sales, revenue, and value analysis by regions of high frequency induction heating machinemarket? All of these failures result in an increase in the impedance being presented to the inverter and therefore a corresponding drop in the current drawn from the inverter. After long-term use, the induction generator of JKZ high-frequency induction heater can still work stably and reliably. It results in large current spikes at the switching transitions as the inverter tries to rapidly charge and discharge the tank capacitor on rising and falling edges of the squarewave. It has functions such as simultaneous materials, preheating, welding, pressure preservation, unloading, etc., which can save time and improve production efficiency. Input voltage: 3-phase 380V, 50HZ/60HZ. Feature on High frequency: Working frequency of SP machines is recommended around 50KHZ, when frequency is over 60KHZ, the machine is designed to lower power automatically to protect the IGBT. This is undesirable for many solid-state inverters as the leading load current causes loss of ZVS and leads to forced reverse-recovery of free-wheeling diodes incurring raised switching losses and voltage overshoots.

High Frequency Induction Hardening Machine Uses

Heat Transfer Surface: Induction Heating. Portable induction welding applications. Ultra high frequency induction heating equipment is mostly used for the industrial metal parts surface quenching. Laminated transformer cores, powdered iron cores and ferrites are all used to prevent eddy currents from flowing inside transformer cores. They are frequently equipped with sections of a material called flux intensifier, which helps to drive the magnetic field in a certain direction in order to intensify heating in that area and make the coil more efficient. Production, Revenue (Value), Price Trend by Type. Effect of Frequency on Induction Heating.

High Frequency Induction Heating Machine

It is a metal heat treatment method that produces a certain induction current on the workpiece surface, rapidly heats the surface of the part at high frequency, and then rapidly quenching. This is very significant since power factors in induction heating applications are typically low. A resource for the production of electricity at a high frequency is utilized to force an alternating current inside a coil. The heat generated melts the glue and seals the foil onto the top of the bottle. Most specifications will require surface hardness measurements along with effective case depths to determine the depth of hardening. Such method can directly generate high temperatures inside metal objects. Therefore it is useful to combine all of these losses into a single "loss resistance. " US$ 3000-5000 / Set. The primary benefits are improvements in strength, fatigue and wear resistance in a localised area without having to redesign the component. High Frequency Induction Heating Equipment not only has technical advantages, but also a revolution in heating methods. Therefore the only real current flow from the inverter is the relatively small amount required to overcome losses in the "PFC" capacitor and the work coil. This means that the work coil can be placed at a location remote from the inverter without incurring massive losses in the feed wires. Applications: Hardening, Quenching, Brazing, Welding etc.

Induction Hardening Companies Uk

The RED traces represent the voltage across the tank capacitor, which is the same as the voltage across the induction heating work coil. How do I request a quotation for High Frequency Induction Heating Machine? For more information, you can contact us by phone or email at your convenience. In theory only 3 things are essential to implement induction heating: Having said this, practical induction heating systems are usually a little more complex. Therefore the capacitive load region is not recommended for achieving power throughput control. The squarewave voltage generated by most half-bridge and full-bridge circuits is rich in high frequency harmonics as well as the wanted fundamental frequency.
Brand: Dly Electric More. Applications: *Gail Wynand. When replacing the inductor, the inductor connecting plate and the transformer contact surface should be sanded clean to maintain good conductivity. Induction Heating Capacitors.

When driven at resonance the current drawn by the tank capacitor and the work coil are equal in magnitude and opposite in phase and therefore cancel each other out as far as the source of power is concerned. Most of its capacitance can be thought of as being in parallel resonance with the work coil, with a small amount providing the impedance matching action with the matching inductor (Lm. ) After-sales Service: Install Machine, Training Worker, Maintenance. To prevent electric shock, ensure that the electrical specifications of the chassis are reliably grounded. One of the most common applications is for sealing the anti-tamper seals that are stuck to the top of medicine and drinks bottles. Saturation Magnetic Induction Intensity: 1. Along with thousands of motivated employees, VEVOR is dedicated to providing our customers with tough equipment & tools at incredibly low prices. Types of Induction Heating Equipment. This operating point gives reduced power throughput and diminished heating effect. There is a also a shift in the resonant frequency of the overall system - This is the price to pay for combining the L-match capacitance and tank capacitance into one unit. Electric Current: AC-DC-AC. Practical implementation.
