ELECTROTECHNICAL STEEL STRIP WITH THE ORIENTED STRUCTURE CONTINUOUS ELECTROLYTIC ETCHING METHOD AND DEVICE FOR THE ELECTROTECHNICAL STEEL STRIP WITH THE ORIENTED STRUCTURE CONTINUOUS ELECTROLYTIC ETCHING Russian patent published in 2019 - IPC C25F3/14 

FIELD: technological processes.

SUBSTANCE: invention relates to the field of electroplating and can be used for the electrical steel strip with the oriented structure continuous electrolytic etching. Method comprises the step of the etching mask formation on the steel strip surface with linear exposed open areas in the mask, centering step, in which the strip center position in the width direction is determined, and the strip is centered based on the position sensor and the centering device results, which are placed directly in front of the electrolytic etching device, and a step of the groove formation by etching, which is performed in the electrolytic etching device by the electric current passing between the electrically conductive roller and placed in the electrolytic bath electrode, at that, the strip is in contact with an electrically conductive roller, is immersed into the electrolytic bath and faces the electrode. Device comprises: the mask forming device, the electrolytic etching device, comprising a bath with the electrode and the electrically conductive roller, the position sensor and the centering device.

EFFECT: limiting of the etched grooves shape oscillations in the direction along the steel strip width.
