Dear Experts;
I have seen and experienced that for demagnetization of Steam turbine or Compressor Rotor journal areas, complete rotor need to be removed from Casing (Turbine / Compressor) and best practice is to hang it, using overhead crane, to avoid its contact with ground.
Is is also possible to do localized demagnetization of rotor sensitive parts (Journals / Thrust disc etc) if rotor is not removed from casing and we have only inspected the bearings?
I would like to know the suggestion / guidance from all experts in the field and any care if this is possible without any Reliability issue.
best regards,
