Residual Stress Measurement in Steel Mill Rolls Using ...

Regeneration of a fatigued roll, by grinding off a sufficiently thick layer, may prevent a fracture of the mill and a costly interruption in the process [Ref. 3]. As the residual stresses in a steel mill roll build up continuously during a campaign it is important to know their level before the installation of a roll in its cage and after a ...

How Neodymium Magnets are Made - KJ Magnetics

The basic compound for most Neodymium magnets is Nd 2 Fe 14 B. In practice, the actual chemical reaction used can be more complicated. A commonly used reaction is: 57 Fe + 8 B + 10 Fe 2 O 3 + 7.5 Nd 2 O 3 + 52.5 Ca -> Nd 15 Fe 77 B 8 + 52.5 CaO. Note that the powder formed by this reaction is slightly different than the Nd 2 Fe 14 B ratio.
