magnetism in steel
Posted by: Elmar van den Elzen (PID_480), E-mail: evde@wxs.nl, on January 12, 2000 at 16:17 :
Dear Sirs,
For a customer we inspect steel rolls (3% chrome) for cold rolling steel strip. In the heavily stessed zones of the roll, where the roll material has probably been deformed, magnetism is introduced. This magnetism is finely distributed and the magnetism extends at least several millimeters into the roll body.
We would like to know the cause of this effect.
- Could magnetism be introduced into steel by local deformation?
- Or is it likely that an external magnetic field can be 'frozen' into the material by deformation?
We would appreciate any help to understand this fenomenon or hear from any cases with similar effects observed.
Thank you,
Lismar Engineering,
Elmar van den Elzen
