Power calculator | induction heating of steel Calculation examples for induction heating of steel / iron with tempreratures up to 300 °C Example for a cylindrical shrink fit Example for generator power Work piece or part outside diameter mm Work piece or part innerdiameter mm Width to be heated mm Mass to be heated kg Generator power kW Temperature difference K Shrink fit dimension mm Heating time sec. Results: Results: Heated mass kg Needed power * kW Needed temperature difference K Heating time* sec. Costs per kWh Cent Costs per kWh Cent Results: Results: Energy costs per part Cent Energy costs per part Cent *Losses of heat radiation and conductivity are not included. Estmation of needed power In general the electrical power of the generator can be estimated as follows considering a certain mass, a preset time and a preset temperature of the work piece: P • t = m • c • ΔT P Generator power [kW] t Heating time [s] m Mass Work piece [kg] c Specific heat capacity [kW s / kg K] ΔT Temperature difference [K] (End temperature minus Starting temperature)
