How to demagnetize a turbine rotor
Thread Content
I have a few questions; I’d like to ask those who know the answer: Does the blade of a turbine rotor become magnetic during its manufacturing process? If the blades or other parts are magnetic, is there a demagnetization step? For demagnetization, is it done after the rotor is manufactured? Is the demagnetization step the final process in manufacturing? How to demagnetize?
Why hasn’t anyone replied kindly? :'(
I don’t understand the processing of steam turbines; I’ll only talk about it from a magnetic perspective. As far as I know, to make something magnetic, either an electric current is needed or it needs to be magnetized by a permanent magnet. It shouldn’t have anything to do with these two things during the processing stage, right? If there is anything incorrect, please feel free to point it out.
Oh, I’d like to know that too; I’m an outsider in this area……
During the processing, part of the current flows through the machine tool and to the part being processed; therefore, demagnetization is necessary in all cases
