Definitions

the object of the invention was to provide a method which enables the production of grain-oriented electrical steel with improved surface properties and with which, moreover, the dissolution of the nitrides during the heating phase of the high-annealing can be accelerated.
the average residence time was typically 20- 35 minutes.
