Summary
  • laboratory simulation allows experiments into
    alternative deperm procedures.
  • Anhysteretic deperm produces more reliable final
    magnetisation AND allows for theoretical
    modelling. Flash D can not be modelled easily.
  • Various theoretical models used to describe
    magnetisation changes in tube and submarine.
  • Its possible to extend this analysis to predict
    the response to past and future deperms.
  • BOTTOM LINE NEW DEPERM IS QUICKER, MORE RELIABLE
    and MORE PREDICTABLE
