Advantages of induction heating equipment with different frequencies of өндөр давтамжтай унтраах төхөөрөмж

1) Дунд давтамжийн индукцийн халаалтын арга

Frequency range: ordinary 1KHZ to about 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 surface quenching of large workpieces, large diameter shafts, large diameter thick-walled pipes, large modulus gears and other workpieces, as well as red punching, forging pressing and smelting of smaller diameter bars. Wait.

2) Ultrasonic induction heating method

Frequency range: Ordinary 20KHZ to 40KHZ (because the audio frequency is 20HZ to 20KHZ, so it is called super audio). Heating depth and thickness, about 2-3mm. It is mostly used for deep heating, annealing, tempering, quenching and tempering of medium-diameter workpieces, heating, welding, and hot assembly of large-diameter thin-walled pipes, and medium gear quenching, etc.

3) Өндөр давтамжийн индукцийн халаалтын арга

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

4) Induction heating method of UHF quenching equipment

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

At the same time, these five kinds of induction heating equipment have certain 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.

①Үндсэн шинж чанарууд: жижиг хэмжээтэй, өндөр хүчин чадалтай, хурдан халаалттай, ил тод цөм, бага эрчим хүч зарцуулдаг.

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

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

④Power saving principle: Uncontrollable rectification, the rectification circuit is fully turned on. 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. The size of the equipment is determined according to the heated workpiece. The heavier the workpiece load, the higher the power, and the lighter the load, the lower the power.
