ESTIMATED POWER REQUIREMENT CALCULATION
For all induction heating applications where workpieces of specific size and mass need to be heated to a specific temperature in a required period of time, you can use the formula below to calculate the approximate power of the generator required:
P = m • c • ΔT / t
Generator power [kW]
Mass Work piece [kg]
Special Heat quantity [kW s / kg K]
Temperature difference [K] (End temperature – Starting temperature)
Heating time [s]
CALCULATION EXAMPLES FOR INDUCTION HEATING OF STEEL/IRON WITH TEMPERATURES UP TO 300 °C.
* Losses due to heat radiation and conductivity are not calculated in this calculation.
