Abstract
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 annealing temperature is, the better the [001] orientation is achieved. In addition, the reduction of the intermediate annealing temperatures improves dc magnetic properties (B/sub 8/, H/sub c/) 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/mm/sup 2/ was 0.28 W/kg, which is less than that of the conventional (300 /spl mu/m) grain-oriented silicon steels by about 50%.
