Approximate calculation of the needed power

For all induction – Heating applications where work pieces with certain dimensions and mass in a required period of time to a given
Temperature have to be heated, you can use the formula below to calculate the estimate power of the needed Generator:

P  =     m • c • ΔT / t

P         Generator power [kW]
m         Mass Work piece [kg]
c          special Heat quantity [kW s / kg K]
ΔT       Temperature difference [K]  (End temperature – Starting temperature)
t           Heating time [s]
