-We investigated the effect of the intermediate annealing conditions on the grain textures and the magnetic properties in thin grain-oriented silicon steel sheets produced by the three-stage rolling method. It was found that the lower the intermediate an- nealing temperature is, the better the orientation is achieved. In addition, the reduction of the intermediate annealing tempera- tures improves dc magnetic properties (Bg, He) and enables to reduce the iron loss in thin silicon steels. The measured iron loss W13/50 under the applied tensile strength of 2 kg/mm2 was 0.28 W/kg, which is less than that of the conventional (300 jxm) grain- oriented silicon steels by about 50 %.
