METHOD FOR PRODUCING A GRAIN-ORIENTED ELECTRICAL STEEL FLAT PRODUCT INTENDED FOR ELECTROTECHNICAL APPLICATIONS

摘要

The invention relates to a method for producing a grain-oriented steel flat product for electrotechnical applications, wherein, in a production step,“decarburising and nitriding annealing”is carried out in two stages. The first stage of the annealing process extends over a first time interval, which comprises heating the cold strip starting from a start temperature to a first target annealing temperature and holding it at this target annealing temperature, and the second stage of the annealing process extends over a second time interval, in which the cold strip is heated to a second target annealing temperature and subsequently held at this target annealing temperature.
