TEXTURES AND MAGNETIC-PROPERTIES OF GRAIN-ORIENTED ELECTRICAL STEEL PRODUCED BY CROSS SHEAR ROLLING

Commercial grain oriented electrical steels were made by cross shear r olling (CSR) with a chosen mismatch speed ratio 1.1. Original sheets o f 0.75 mm thick, which had been produced by conventional cold rolling and intermediate annealing were rolled to thickness from 0.35 mm to 0. 15 mm, and followed by industry annealing. The deformation texture and the magnetic properties were measured. Results indicate that: in the condition of the CSR, the deformation texture of rolled sheet is gener ally similar to that of conventional rolled sheet; for sheets with the thicknesses from 0.35 mm to 0.25 mm, favorable deformation textures, mainly consisting of {111}[112], are also found at subsurface layers, which may help produce sharp Goss texture, and after the final anneali ng, the magnetic properties of sheets are not lower than that of conve ntional rolled sheets.
