Different frequencies of GuangYuan · GuangZhiYuan induction heating equipment have different advantages. Below, Guangyuan · guangzhiyuan shares the advantages of different frequencies of induction heating equipment.
1. Low frequency induction heating mode
The frequency is the lowest, frequency range: power frequency (50 Hz) to 1 kHz, the commonly used frequency is power frequency. The relative heating depth is the deepest and the heating thickness is the largest, about 10-20m. It is mainly used for overall heating, annealing, tempering and surface quenching of large workpieces.
2. Medium frequency induction heating mode
Frequency range: normal 1kHz to 20kz, the typical value is about 8kz. The heating depth and thickness are about 3-10m. It is mainly used for heating, annealing, tempering, quenching and surface quenching of large workpieces, large diameter shafts, large diameter thick wall pipes, large modulus gears and other workpieces, as well as red punching, forging and pressing of small diameter bars
3. Super audio induction heating mode
Frequency range: about 20KH to 40KHz (because the audio frequency is 20Hz to 20kHz, it is called super audio). Heating depth, thickness, about 2-3m. It is mainly used for deep heating, annealing, tempering, quenching and tempering of medium diameter workpiece, heating, welding, hot assembly of large diameter thin-walled pipe, quenching of medium gear, etc.
4. High frequency induction heating mode
Frequency range: common 40KHz to 200Hz, common 40KHz to 80kHz. Heating depth, thickness, about 1-2m. Induction heating surface quenching equipment is mainly used for deep heating, red punching, forging, annealing, tempering, quenching and tempering of small workpieces, surface quenching, heating and welding of medium diameter pipes, hot assembly, pinion quenching, etc.
5. UHF induction heating mode
Relatively the highest frequency, frequency range: more than 200kh, up to tens of MZ. The heating depth and thickness are the smallest, about 0.1-1m. It is mainly used for quenching and welding of local tiny parts or extremely fine bars, surface quenching of small workpieces, etc.
At the same time, these five kinds of induction heating equipment have some advantages. They all use IGBT induction heating power supply, which is the most energy-saving and environmentally friendly induction heating equipment in the 21st century.
① Main features: small volume, high power, fast heating, transparent core and low power consumption.
② Power saving situation: compared with the old SCR medium frequency, the power consumption of SCR medium frequency heating per ton of workpiece is about 470 degrees. Our new medium frequency power consumption is about 350 degrees. More than 100 kilowatt hours of electricity will be saved for each ton burned. As long as it burns about 500 tons, the saved electricity charge can recover the equipment investment.
③ Circuit features: the main device adopts igbi module. The circuit does not control full bridge rectification, capacitor filtering, bridge inverter and series resonant output. It is fundamentally different from the old medium frequency using thyristor parallel resonance.
④ Energy saving principle: uncontrollable rectifier, rectifier circuit is fully on. High power factor, voltage type series resonance and so on, determine that this equipment greatly saves power.
