Abstract

The structure

0.009 6N) from 2. 66 mm hot-rolled plate normalizing at 1 100 ℃ for 2 min

air cooling for 10 s to 960 ℃ for 3 min

air cooling

then first cold-rolling

process annealing and second cold-rolling to 0.3 mm sheet

and through primary recrystallizing annealing at 820 TI for 5 min

air cooling and secondary recrystallizing annealing at 1 050 ℃

air cooling have been

tested and studied. As contrasted to the structure and properties of primary recrystallizing annealed samples and secondary recrystallizing annealed samples without via hot-rolled plate normalizing process

the effect of normaliz

ing process on annealing process is obtained. Results show that the normalizing treatment of hot-rolled plate may decrease the primary recrystallizing grain size of the primary annealed cold-rolled sheet

increases the percentage of Σ

grain boundaries and high-angle grain boundaries

improves the content of Goss orientation grains

and can coarsen the secondary recrystallizing grains

enhance the magnetic induction and decrease the iron loss.
