2.How to choose the right induction heating equipment?
Induction heating equipment has two main technical parameters: output power and operating frequency.
The penetration depth of the workpiece mainly depends on the working frequency: the lower the frequency, the deeper the heat penetration; the higher the frequency, the shallower the penetration, so the optimal heating frequency should be selected according to the actual application to reach best heating efficiency .
Output power affect the heating rate: Generally according the weight of the heated workpiece, the requirement of heating temperature and heating rate to select the power.

heat treatment |
A metal hot working process for treating the solid state Materials by heating, insulation and cooling, in order to obtain the desired organization and performance.Such as hardening, annealing, normalizing, tempering, quenching. |
Shaft, gear, sprocket, machine tool guide, hardware tools, automobile and motorcycle parts, stainless steel, copper strips, copper wire, lead screw etc. quenching, annealing, tempering, normalizing, etc. |
the deeper the heat penetration,the lower the frequency Heat penetration frequency 0.2-0.8mm ≧100KHz 1.0-1.5mm 20-50KHz 1.5-2.0mm 15-25KHz 2.0-3.0mm 8-20KHz 3.0-5.0mm 4-10KHz ≧5.0mm 0.5-6KHz
|
The larger the quenching area, the deeper the penetration, the shorter the time, the greater the power |
Diathermy |
In the heating process, ensure the entire center of the workpiece and the surface temperature difference within the technical requirements |
Standard parts, fasteners, hardware tools, auto parts, rigging, pipe fittings, drill and other hot forging hot-rolled |
The larger the workpiece diameter, the lower the frequency
Φ≧40mm:0.5-15KHz Φ16-40mm:10-45KHz Φ4-16mm:40-100KHz Φ≦4mm:≧100KHz |
Select the equipment power according the weight of the workpiece and the heating rate |
smelting |
A pyrometallurgical process, which put metal materials and other auxiliary materials into the furnace for melting and conditioning, the materials in the high temperature furnace take some physical and chemical changes, output crude metal or metal enrichment and slag |
Gold, silver, copper, aluminum, iron and other metals |
Frequency generally depends on the capacity of the melting furnace (or crucible) size: small capacity, high frequency, large capacity, low frequency |
Power depends on the melting furnace (or crucible) capacity and time requirements |
Brazing |
A method of using a metal material with lower melting point than the base metal as a brazing material, heating the weldment and the brazing filler metal to a temperature higher than the melting point of the brazing filler metal, but lower than the melting point of the base metal, wetting the base metal with the brazing filler metal, filling the joint gap, Mutual diffusion to achieve connecting the weldment |
Diamond saw blades,carbide cutting tools (turning tools, milling cutters, drills), mining tools (drill bits, coal drill), refrigerator compressor tubes, transformer copper wires, motor copper wires, automotive pipe fittings copper, silver and tin brazing |
The larger the workpiece size, the lower the frequency of selection. Such as turning tools welding: ≦20mm ≧30KHz ≧20mm 10-35KHz |
The larger the heating volume of the brazed matrix, the faster the welding time of the single piece, the greater the selected power. |
Others |
Aluminum-plastic composite pipe, hot wire coating; bottle mouth aluminum foil seal for food, pharmaceutical industry ;Motor stator hot installed |
|
For non-magnetic materials, the frequency is higher |
The shorter the required heating time , the greater the power |
The above are several simple choices based on practical applications, if you need detailed equipment information for your product, please email to tell us your specific technical requirements, our engineers will calculate according to technical requirements for you to recommend the appropriate Induction heating equipment and solutions. At the same time, depending on your technical requirements, we will design the right equipment to test the samples and demonstrate our machine performance.
