How to select the frequency of induction.

 Induction heating equipment, according to a different output frequency, which can be broadly classified into: ultra-high frequency, high-frequency, super audio, frequency, etc. Different requirements of heating process required a different frequency, if the frequency of selection errors can not meet the heating requirements. Heating time such as slow, inefficient job, uneven heating, temperature fail, easily lead to damage to the workpiece and so on.

Choosing the correct frequency, first of all,  It is necessary to know the technical requirements of heating products, the mainly situations are as follows:

 1,workpiece through hot, such as: high strength bolt, nut, auto parts, hardware tools, rigging, the hot upsetting of hot-rolled  twist drill and so on, The longer of the workpieces diameter, the lower of the frequency .Such as:

Φ4 mm and the following was applicable to the high frequency, UHF (100-500KHz) Φ4-16 mm applies to the high-frequency (50-100 KHz)

 Φ16-40 mm applies to VHF (10-50 KHz) Φ40 mm more than the application of intermediate frequency (0.5-10 KHz)

 2,heat treatment, shaft, gear, quenching and annealing stainless steel products and put quenching as an example, The shall lower of the quenching layer. the higher of the frequency. The deeper of the quenching layer. the lower of the frequency. Such as: hardening layer

0.2-0.8mm applicable UHF 100-250 KHz, high-frequency 1.0-1.5mm applicable 40-50 Khz high-frequency, super-audio

1.5-2.0mm applicable VHF 20-25 Khz 2.0-3.0mm applicable VHF 8-20 KHz, IF

3.0-5.0mm applicable 4-8 KHz IF 5.0-8.0mm applicable 2.5-4 Khz IF

 3, Welding, Welding head, lathe tool, reamer, milling cutter, drill bits, and stainless steel bottom of the pot, such as the composite of different materials welding, and welding the greater volume and frequency should be reduced more to welding tools as an example, such as:

20mm cutter following the application of high-frequency 50-100 KHZ20-30mm above the tool to apply high-frequency 10-50 KHZ, super audio 30 mm above the tool applies to 1-8 KHZ IF

4, melting gold, silver, copper, lead and other  precious metals .According to a furnace and the production efficiency of the specific, small-capacity high-frequency options, most used to super audio, super audio frequency to meet the casting industry in general applications, It can melt 200Kg aluminum ingots per hour in general .
