The Effect of Reduction on Microstructure and Texture of Silicon Steel SheetsTransformers Core, after the last stage Cold Rolling

Grain oriented silicon steel sheets have been widely used in transformers and electrical motors. The manufacturing process of grain oriented silicon steel is: steel making and casting, reheating, hot rolling, cold rolling, decarburizing annealing, coating and final annealing. Cold rolling of silicon steel sheets is performed to reduce the thickness of sheets and prepare the necessary driving force for the next steps. Amount of strain is important because of the condition of recrystalization. In this research project the effect of strain on the structure characteristics and texture of silicon steel sheets is investigated. The results of this project show that with more reduction of Cross section , characters <112> {III} which is one of the most important characters In the microstructure, will rise.
