Sažetak

The effect of hot rolling temperature on microstructures and textures of grain oriented silicon steel was studied by optical microscopy (OM), zeiss ultra 55 Scanning electron microscope (SEM) and Electron backscatter diffraction (EBSD) technique respectively. The results show that being hot rolled at 1 152 °C and 1 227 °C respectively, the effect of hot rolling temperature on microstructures of hot rolled and normalized sheets is little, and there is only a small difference in grain size between the samples. Secondary recrystallization is difficult to occur in the medium temperature sample due to the lack of sufficient inhibitors in the sample. The major deformed texture component in center region of hot rolled sheets is {114}<481> which has obviously heredity, and it is more sharp in low temperature sample.
