FABRICATION OF TEXTURED STEEL SHEET Russian patent published in 2015 - IPC C21D8/12 C21D1/09 

Abstract RU 2547377 C2

FIELD: process engineering.

SUBSTANCE: invention relates to production of textured steel sheet with minimised losses for flux reversal and optimised magnetostriction properties. Proposed process comprises the steps that follow. a) production of steel sheet, b) laser processing of said sheet by laser beam of power P. Note here that linear strains are formed on steel sheet surface arranged with interval a. b) steel sheet full power S1,7/50 is measured before and after laser processing. Note here that laser processing parameters are varied to make the difference between measured full powers S1,7/50 before and after processing making smaller than 40%.

EFFECT: optimised properties of steel sheets for production of transformer parts.
