Transformer lamination heat treatment
Transformer lamination heat treatment
(OP)
Hi guys,
I have to heat treat mumetal transformer lamination 30x25x0,35 mm and wonder do I have to expect some dimensional variation(heat treatment at 1050°C under hydrogen atmosphere). Also, do I have to take care about placing the parts (they are mgo coated)? Is there a chance of deformation if the parts are placed randomly? Do I have to prepair some special tool to keep them tight?
I don't find any clues on this point... Thanks

You need to have good flat support under them so that they remain flat.

Not like Fe-Co, mumetal is not supposed to have any growth or shrinkage after heat treatment. especailly for your small rings with a relatively big thickness, dimensional distortion should not be a big issue.

For big sized lams, you can also try to hang your lams on some rod, using lam itself weight to keep the shape.
