  • Patent number: 10533263
    Abstract: Method for continuous electrolytic etching of a grain oriented electrical steel strip includes: forming an etch mask on a surface of a grain oriented electrical steel strip cold-rolled to final thickness with a linear exposed portion exposed from the etch mask; centering the grain oriented electrical steel strip with a position sensor and centering apparatus, which are placed immediately upstream of an electrolytic etching apparatus; and performing an electrolytic etching process in which electrolytic etching is performed in the electrolytic etching apparatus to form a linear groove on the surface of the grain oriented electrical steel strip by passing electric current between a conductor roll and electrode placed in an electrolytic bath while the grain oriented electrical steel strip is brought into contact with the conductor roll, the grain oriented electrical steel strip is immersed in the electrolytic bath and the grain oriented electrical steel strip is facing the electrode.
