Select power supply according to the power and frequency. The higher the frequency, the shallower the heating depth, and the lower the frequency, the better the diathermancy.

Heating principle

The principle of high frequency induction heating is that apply high frequency alernating current to a conduct that is curled to cyclic (normally copper tube) to produce flux, then put the metal to this area to make the flux to run through it, and eddy current will be generated in the deriction of self-capturing with flux(rotary current), the induced current then generates heat under the influence of the eddy current, so this heating method is called induction heating. hence, metal and other objects under heated can be heated without contact. at this moment, the character of the eddy current relies in that the induction heating on the object nearby the coil is outwardly strong but inwardly weak. with this principle. this heating body can be concentratedly heated where needed to achieve instantly effect, thereby the production output and work capacity are both improved.

FAQ

Q: Why use induction heating?

A: 1,Induction Heating is a GREEN process as it does not emit fumes or CO2 into the environment, emissions are controlled by the electricity generating company at one site and are easy to monitor.

2, The result of only a small proportion of the material being heated, commonly less than 5% of the mass being heated to accomplish the required properties, then there is less energy consumed, overall, to heat treat the component when compared with conventional furnace heat treatment methods.

3, Again due to the small areas heated there is a considerably reduced heat treatment distortion so much so that the majority of the components we heat treat are ready for assembly after heat treatment.

4, Grinding costs can constitute 25 - 30% of the total cost of a component. Modern CNC lathes can turn components more accurately to size than they can be ground and with a better surface finish. Save money by specifying induction hardening.

5, Some components require some areas to remain soft after heat treatment. This can only be achieved in a furnace by stopping off the component. The stopping off technique alone is usually more expensive than the cost of the induction hardening process and the induction process only hardens the portions required to be hard.

Q: Why choose induction brazing?

A:Induction heating technology is steadily displacing open flames and ovens as the preferred heat source in brazing. 6 key reasons explain this growing popularity.

1, Speedier solution. Induction heating transfers more energy per square millimeter than an open flame. Put simply, induction can braze more parts per hour than alternative processes.

2, Quicker throughput. Induction is ideal for in-line integration. Batches of parts no longer have to be taken aside or sent out for brazing. Electronic controls and customized coils let us integrate the brazing process into seamless production processes.

3, Consistent performance. Induction heating is controllable and repeatable. Enter your desired process parameters into the induction equipment, and it will repeat heating cycles with only negligible deviations.

4, Unique controllability.Induction lets operators view the brazing process, something that is difficult with flames. This and precise heating minimize the risk of overheating, which causes weak joints.

5, More productive environment. Open flames uncomfortable working environments. Operator morale and productivity suffer as a result. Induction is silent. And there is virtually no increase in ambient temperature.

6, No-contact process. Induction produces heat within the base metals —and nowhere else. It’s a no-contact process; the base metals never come into contact with flames. This protects the base metals from warping, which in turn increases yield and product quality.

Q: How to choose a suitable induction heater?

A: Induction heaters have many different modles with different power and frequency.

1, The higher power, the faster of the heating speed. so if you want to heat fast then you'd better choose a high power induction heater.

2, The higher frequency, the lower of the heating layer. So for some surface hardening, we suggest use a higher frequency heater, for some entire heating (like forging and melting) we suggest to use low frequency heater.

3, If you are not sure of which model is suitable for your work, please ask our salesman for suggestion before you place an order.
