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 theย desired temperature results in adequate expansion to allow forย placing of the flange over a graphite seal.
Material Graphite sealย 1โ (25.4mm) diameter steel flange
Temperature indicating paint
Temperature 700ยฐF (370ยฐC)
Frequency 206 kHz
Equipment DW-UHF-4.5kW, 150-400 kHz solid state induction powerย supply, equipped with a remote heat station containing oneย 0.66 ฮผF capacitor.
A three-turn helical induction heating coil designed andย developed specifically for this application.
Process The part is placed inside the induction heating coil and powerย is supplied to the coil until the steel heats. This is done toย determine the time-to-temperature and the heating pattern onย the part.
The composite assembly heats uniformly and reaches 700 Fย (370ยฐC) in 10-12 seconds.
Results/Benefits When the steel reaches the desired temperature it easily slipsย on to the graphite.
Benefits include uniform, precise heat with quick heat upย cycles.
