In the present work, the interaction of Sb and initial annealing before single-roll drive rolling on the microstructure, crystallographictexture, and magnetic behavior of 1.2 wt% Si steel was studied. Steel ingots with different antimony percentageswere produced under the Ar atmosphere. After homogenization, they were subjected to symmetric hot-rolling. The producedsheets were then divided into two groups. The first group was cold-rolled to 1 mm thickness using a single-roll drive rollingmachine, while the second group was subjected to initial annealing before asymmetric cold-rolling. Finally, all sampleswere annealed at 1000 °C for 3 min. Microstructural studies showed that with the addition of antimony, the mean grain sizeof samples was decreased. This effect was less significant in samples subjected to initial annealing. Moreover, the additionof antimony positively affected the desired texture. In specific, it yielded a gradual increase of θ-fiber in samples. Theintensity of θ-fiber was higher in samples subjected to initial annealing compared with those without initial annealing. Thecomparison of the effect of average grain size and texture on magnetic behavior showed that grain size acted as the dominantparameter as the coercivity and remanence increased with decreasing grain size. However, in constant grain size, thetexture played the main role in enhancing the magnetic behavior by increasing the θ-fiber intensity. The results showed thatthe combination of antimony and initial annealing before single-roll drive rolling resulted in the best magnetic performancein a low silicon steel sheet.
