The equation is follows: Penetration depth by induction heating is equal to the square root of resistively, divided by the product of pi, magnetic permeability, and frequency. Feature on low frequency: primary coil voltage of SP machine is very high, when the frequency is low, this will cause magnetic saturation of the magnetic core, so SP machine can not work well at low frequency; SPG50K machines do not have this problem. The high-frequency 15 kW induction heater uses advanced technology, simple and easy to operate, high efficiency, low energy consumption, high output power. It can save 2/3 of the power than the high frequency of the electron tube. Both of these factors contribute to a reduction in the real power throughput. High frequency induction hardening machine for dogs. Other applications include melting, welding and brazing or metals.
Many heat treaters have one old induction machine sitting in the corner of the shop floor, with one remaining employee who knows how to operate it. The components are heated by means of an alternating magnetic field to a temperature within or above the transformation range followed by immediate quenching. Induction hardening boosts throughput. The control panel is simple and easy to operate, the key functions are manifest at a glance, and the operation is safer. When the device needs to be repaired or maintained, it must be repaired after the power is off. This shows the voltage across the work coil under normal operation when driven close to resonance. Increasing the voltage and decreasing the current allows common switch mode MOSFETs (or fast IGBTs) to be used. High frequency induction hardening machine for water. For induction hardening, frequencies are split into two groups: medium frequency (MF) and radio frequency (RF). Max Input Power: 80kw. It has automatic and manual welding functions, and its operation is simple and practical. Although this information just begins to scratch the surface of the terminology and fundamentals of the process, hopefully it provides a starting point to those with limited experience. Looking to the right of the white line we have the area shaded in blue labelled "Inductive Load region. " Power is only sourced to the work coil in the time that the devices are switched on.
Low maintenance costs. In other heating techniques, heat is produced by a heating element or a flame, and applied to the work piece. It is fed from a smoothed DC supply with decoupling capacitor across the rails to support the AC current demands of the inverter. From these graphs we can deduce a few implications for any control system that must track the resonant frequency of the LCLR arrangement and control power throughput. Certificate: CE More. 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. It is easier to design a conventional ferrite power transformer for these conditions. High frequency induction hardening machine for hair. Dimensions: Host machine - L550×W255×H540. This resistance represents the only component that can consume real power, and therefore we can think of this loss resistance as the load that we are trying to drive power into in an efficient manner. This means there is no voltage across the work coil arrangement and no current flows through the work coil. Melting Capacity: 500kg to 10 Tons More.
If isolation transformers are included in the designs then they need not even run from the same supply! Get in Touch with Us: Mr. Benni Johnson. Market Segment By Types: The Welding Equipment, Heat Treatment Equipment and Annealing Equipment. High frequency induction heating machines. This softens the hardened area slightly in order to increase the toughness of the part and improve crack susceptibility. Typical applications are powertrain, suspension, engine components and stampings. 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. Equipment and Tooling.
Types of Induction Heating Equipment. Here is an explanation of why this is so . Principle: Induction Heating. Widely used in brazing, silver welding, hot forging, melting, quenching, etc. A ring of conductive material called a "getter" is placed inside the evacuated glass vessel. Tool welding, paper cutting knife, shoe blade quenching. The job of the matching network is simply to transform this relatively large loss resistance across the tank circuit down to a lower value that better suits the inverter attempting to drive it. Effect of Increasingly High Frequency on Induction Heating - Bright Hub Engineering. Send Email: Address:420 Lexington Avenue, Suite 300 New York City, NY 10170, United States.
