EQUIPMENT FOR THE CONTINUOUS CONTACTLESS CONTROL OF THE STRUCTURAL CONDITION OF A COLD-DRAWN BAND

Internal structure of a metal strip is monitored by applying cyclically varying magnetic flux to the strip and sensing the flux induced in the strip. Signals corresponding to the magnetic field intensity of the applied cyclically varying field and to the resulting induced flux indicate the loss of e...

description Internal structure of a metal strip is monitored by applying cyclically varying magnetic flux to the strip and sensing the flux induced in the strip. Signals corresponding to the magnetic field intensity of the applied cyclically varying field and to the resulting induced flux indicate the loss of energy due to the internal structure of the strip. Making a similar determination by similar monitoring apparatus following annealing of the strip allows the effect of the annealing to be determined. The signals from the two monitoring apparatus can be used to generate a comparison signal to control the operation of the annealing treatment apparatus.
