The hot band annealing treatment is favorable to improve the magnetic properties of non-oriented electrical steel. The magnetic induction (B 50) of the final annealed sheet from hot band annealing process reached 1.712 T, which was significantly higher than without hot rolled band annealing (1.693 T). Meanwhile, the iron loss at different ... WebA Complete Process Guide. Annealing is a heat treatment process that changes the physical and sometimes also the chemical properties of a material to increase ductility and reduce …
WebSep 15, 2016 · A direct correlation has been found between the severity of coarse-grain banding and ridging phenomenon. In order to overcome the ridging defect by restricting the formation of coarse grain sized bands, hot-band annealing at sufficiently high temperature (~ 940 °C) has been found to be necessary, prior to the cold-rolling and annealing operation. WebFeb 7, 2024 · Variations of the Final Texture Due to Hot Band Annealing Steel without hot band annealing. The textures of the final annealed steel without hot band annealing are shown in Fig. 1.After final annealing at 700 °C, the texture is dominated by three major components, i.e. a {001} <130> (~15° from the cube) on the θ-fiber (<001>//ND), a {331} …
WebWith the increase of hot band annealing temperature, the inclusions of 0.1–1 μm in hot band obviously reduced, the area fraction of {100}<110> texture prominently increased during recrystallization of hot band.
