We investigated the effect of rolling conditions on the textures and magnetic properties in order to advance the reduction of iron loss in thin grain-oriented silicon steel sheets which can be produced by using the three-stage rolling method. In this contribution, it was clarified that the sheets are completely covered with highly oriented (110) grains when the amount of the rolling reductions become more than 50 % in all the rolling processes. Consequently, thin silicon steel sheets with the highest value of B8 (the magnetic induction at 800 A/m) can be produced under the same optimum condition.
