How to calculate the power of induction heating equipment?

Calculation of the power of equipo de calentamiento por inducción P=(C×T×G)÷(0.24×S×η) Remarks of induction heating equipment:

1.1 C=Material specific heat (kcal/kg℃)

1.2 G = Workpiece weight (kg)

1.3 T=Heating temperature (℃)

1.4 t = tiempo (S)

1.5 η = heating efficiency (0.6)

2. Quenching power calculation of induction heating equipment P=(1.5—2.5)×S2.1S=the area of the workpiece to be quenched (square centimeters)

3. Calculation of melting power of induction heating equipment P=T/23.1T= electric furnace capacity (T)

4. Frequency calculation of induction heating equipment δ=4500/d24.14500=coefficient

5. d=workpiece radius
