Different frequency heating depths of visokofrekventna oprema za gašenje su različiti

1) Medium frequency induction heating method

Frequency range: normal 1KHZ to 20KHZ, the typical value is about 8KHZ. The heating depth and thickness are about 3-10mm. It is mostly used for heating, annealing, tempering, quenching and tempering and surface quenching of larger workpieces, large diameter shafts, large diameter thick wall pipes, large modulus gears, and red punching, forging and smelting of smaller diameter bars. Wait.

2) Super audio frekvencijska metoda indukcijskog grijanja

Frekvencijski raspon: obični 20KHZ do 40KHZ (jer je audio frekvencija 20HZ do 20KHZ, pa se naziva super audio). Dubina i debljina grijanja su oko 2-3 mm. Najviše se koristi za dubinsko zagrijavanje, žarenje, kaljenje, kaljenje i kaljenje izradaka srednjeg promjera, zagrijavanje, zavarivanje, toplinski sklop tankostijenih cijevi većeg promjera i srednjeg zupčaničkog kaljenja.

3) High frequency induction heating method

Frequency range: normal 30KHZ to 100KHZ, commonly used 40KHZ to 80KHZ. The heating depth and thickness are about 1-2mm. Induction heating surface hardening equipment is mostly used for deep heating, red punching, forging, annealing, tempering, quenching and tempering, surface quenching, heating and welding of medium diameter pipes, hot assembly, pinion quenching, etc. of small workpieces.

4) Induction heating method of ultra-high frequency quenching equipment

The frequency is relatively high, the frequency range: above 200KHZ, up to 1.1MHZ. The heating depth and thickness are small, about 0.1-1mm. It is mostly used for the quenching and welding of local very small parts or very thin bars, and the surface quenching of small workpieces.

Istovremeno, ovih pet vrsta opreme za indukcijsko grijanje imaju određene prednosti. Svi koriste IGBT indukcijske izvore napajanja. Oni su najštedljivija i ekološki najprihvatljivija oprema za indukcijsko grijanje u 21. stoljeću.

① Glavne značajke: mala veličina, velika snaga, brzo zagrijavanje, prozirna jezgra, niska potrošnja energije.

②Power saving situation: Compared with the old-fashioned thyristor intermediate frequency, the thyristor intermediate frequency heating uses about 500 degrees per ton of workpiece. Our company’s new intermediate frequency power consumption is about 300 degrees. Each ton burned saves more than 200 kilowatt-hours of electricity, which is 30% more energy-saving than the old test.

③ Circuit characteristics: The main device adopts IGBT module, the circuit does not control full bridge rectification, capacitor filtering, bridge inverter, series resonance output. It is fundamentally different from the old-fashioned intermediate frequency using thyristor parallel resonance.

④Power saving principle: Uncontrollable rectification, and the rectifier circuit is fully conductive. High power factor, voltage type series resonance, etc., determine the substantial power saving of this equipment. The power automatic tracking technology of the equipment, the equipment will automatically adjust the output power according to your workpiece. Determine the size of the equipment according to the heated workpiece. The heavier the workpiece load, the greater the power, and the lighter the load, the lower the power.
