Induction heating is a form of non-contact heating for conductive materials, when alternating current flows in the induced coil, varying electromagnetic field is set up around the coil, circulating current(induced, current, eddy current) is generated in the workpiece(conductive material), heat is produced as the eddy current flows against the resitivity of the material.
Induction heating is a rapid ,clean, non-polluting heating form which can be used to heat metals or change the conductive material’s properties. The coil itself does not get hot and the heating effect is under controlled. The solid state transistor technology has made induction heating much easier,cost-effective heating for applications including soldering and induction brazing ,induction heat treating, induction melting,induction forging etc.<
How to select the best induction heating equipment for your application? What frequencies are best suited to your applications?The guide below will give you some idea of induction’s potential.
How much energy do you need?
Before calculating your energy requirements you first need to know:
• The type of material (steel, copper, brass, etc.)
• Workpiece dimensions
• Desired hourly production
• Desired final temperature
Calculate your energy requirements
Step 1 First determine the material’s energy absorption rate. Fig.1 shows rates for some common materials.
Step 2 Multiply the energy absorption rate by your desired hourly production (kg/hour). The result is your specific power requirement.
Step 3 You can now ascertain the overall efficiency level of the induction equipment. Some typical induction heater efficiency levels for common materials are listed in Fig.2. Divide the calculated specific power need by the equipment efficiency rate. This gives you the total power requirement.
Selecting the right frequency
The choice of frequency is crucial when using induction heating, as frequency determines the heat’s penetration depth. Fig. 3 shows approximate frequencies for through-heating some common materials.
