Induction Heating Shrink Steel Flange
Description
Induction Heating Shrink Steel Flange With IGBT Heating Fitting Units
Objective To heat steel flange for heat shrink application. Reaching theĀ desired temperature results in adequate expansion to allow forĀ placing of the flange over a graphite seal.
Material Graphite sealĀ 1ā (25.4mm) diameter steel flange
Temperature indicating paint
Temperature 700Ā°F (370Ā°C)
Frequency 206 kHz
Equipment DW-UHF-4.5kW, 150-400 kHz solid state induction powerĀ supply, equipped with a remote heat station containing oneĀ 0.66 Ī¼F capacitor.
A three-turn helical induction heating coil designed andĀ developed specifically for this application.
Process The part is placed inside the induction heating coil and powerĀ is supplied to the coil until the steel heats. This is done toĀ determine the time-to-temperature and the heating pattern onĀ the part.
The composite assembly heats uniformly and reaches 700 FĀ (370Ā°C) in 10-12 seconds.
Results/Benefits When the steel reaches the desired temperature it easily slipsĀ on to the graphite.
Benefits include uniform, precise heat with quick heat upĀ cycles.
