Improvement of recrystallization texture and magnetic property in non-oriented silicon steel by asymmetric rolling

Asymmetric rolling (ASR) with different circumferential speed between working rollers was applied in cold rolling process of non-oriented silicon steel, and the effects of ASR on recrystallization texture and magnetic properties after final annealing were investigated ASR can improve the recrystallization texture by an obvious enhancement of eta fiber (< 001 > parallel to RD), resulting in a decrease of iron loss and an increase of magnetic induction. The application of ASR in first pass, last pass or all passes was more efficient compared with ASR in both first and last passes. (c) 2007 Elsevier B. V. All rights reserved.
