Abstract

Non-oriented 3% silicon steel sheets were cold-rolled to 0.1 mm thick by various methods, and then they were finally annealed in an argon atmosphere for 1.5 hours at 900°C with a cooling rate of 0.025°C/s. Their magnetic properties changed depending on cold-rolling method used. A sample which had magnetic two-easy-directions with strong (100) cubic texture was obtained in the following way. The sample was alternately cold-rolled in two perpendicular directions L and T, and was also subjected to an intermediate anneal. The average grain diameter of the sample was 57 μm. Its magnetic induction at 800 A/m was 1.65 T in the L direction, and 1.62 T in T direction, respectively
