| Abstract Scope |
Conventional cold rolling is a plane-strain compression process (2D), which normally produces very similar deformation and final annealing textures, i.e., the <110>//RD (rolling direction) and <111>//ND (normal direction) fibers, which are not the desired orientations for good magnetic properties. In this study, skew cold rolling is employed to process non-oriented electrical steel, in which the hot-rolled steel plates are fed into the rolls at different angles (22.5° and 45°) from the conventional rolling direction. This rolling scheme generates a unique three-dimensional (3D) deformation mode that can significantly alter the cold rolling texture, which in turn, leads to different recrystallization texture. A 2.8 wt% Si non-oriented electrical steel is skew cold rolled and the recrystallization of the steel is investigated by annealing the sheets at 1050 °C for different times (30 seconds and 60 seconds) to capture both partial and complete recrystallization. The results are compared to those after conventional rolling and cross rolling. It is shown that skew rolling can significantly enhance the <001>//ND texture (desired for good magnetic properties), and largely reduce or eliminate the detrimental <111>//ND texture. |
