Advantages of different frequency induction heating equipment for high frequency quenching equipment

發布時間:2021-11-29 點擊量:
1) if induction heating mode

Frequency range: ordinary 1KHZ to 20KHZ or so, the typical value is about 8KHZ. Heating depth, thickness of about 3-10mm. For larger workpieces, large diameter shaft, large diameter thick walled tube, big modulus gear and other parts of the heating, annealing, tempering, quenching and tempering and surface hardening and smaller diameter bar red, forging, melting etc..

2) ultra audio frequency induction heating mode

Frequency range: normal 20KHZ to 40KHZ or so (because the audio frequency is 20HZ to 20KHZ, so call it super audio). Heating depth, thickness, about 2-3mm. It is widely used for deep heating, annealing, tempering, quenching and tempering of medium diameter workpieces, heating and welding of large diameter thin wall tubes, heat assembly, medium gear quenching and so on.

3) high frequency induction heating mode

Frequency range: ordinary 30KHZ to 100KHZ or so, commonly used 40KHZ to 80KHZ. Heating depth, thickness, about 1-2mm. Induction heating surface quenching equipment for heating, deep red small workpiece punching, forging, annealing, tempering, quenching and tempering, surface hardening, medium diameter pipe heating and heat welding, assembly, small gear quenching etc..

4) induction heating mode of ultra high frequency quenching equipment

Frequency is relatively high, frequency range: more than ordinary 200KHZ, up to 1.1MHZ. Heating depth, thickness of the smallest, about 0.1-1mm. It is mainly used for local minimum position or very thin bar quenching, welding, surface hardening of small workpieces, etc..

At the same time, these five kinds of induction heating equipment have certain advantages, are using IGBT induction heating power supply, is the most energy saving and environmental protection of the twenty-first Century induction heating equipment.

Main features: small size, large power, fast heating, the core of the Department of electricity.

The energy-saving situation: compared with old SCR thyristor medium frequency heating, electricity 500 degrees per ton of workpiece. My new medium frequency power consumption 300 degrees. Burn more than and 200 tons per ton of electricity, energy saving than the old test of thirty percent.

Circuit characteristics: the main device using IGBT module, the circuit does not control full bridge rectifier, capacitor filter, bridge inverter, series resonant output. There is a fundamental difference between the old and the medium frequency silicon controlled thyristors.

The power saving principle: rectifier, rectifier circuit full conduction. High power factor, voltage series resonance and so on. Automatic tracking technology of equipment, the device will automatically adjust the output power according to the size of your work. Determine the size of the device according to the heated workpiece. The heavier the load, the greater the power, the lighter the load and the smaller the power.
