EFFECT OF ROLLING CONDITION ON TEXTURES AND MAGNETIC-PROPERTIES IN THIN GRAIN-ORIENTED SILICON STEEL SHEETS

We investigated the effect of rolling conditions on the textures and m agnetic properties in order to advance the reduction of iron loss in t hin grain-oriented silicon steel sheets which can be produced by using the three-stage rolling method. In this contribution, it was clarifie d that the sheets are completely covered with highly oriented (110) gr ains when the amount of the rolling reductions become more than 50 % i n all the rolling processes. Consequently, thin silicon steel sheets w ith the highest value of B-s (the magnetic induction at 800 A/m) can b e produced under the same optimum condition.
