In order to further decrease the manufacturing costs of high grade non-oriented silicon steel
through optimizing process of hot deforming
dynamic crystal was promoted
low-cost high grade non-oriented producing by the method of no-normalizing**one-step cold rolledr,would be one possibility. Based on silicon steel of 2. 5% ( Si + Al)
as close as possible to the actual production situation
the process were simulated by Gleeble-1500D thermal simulation test machine
with constant strain rate 0. 1s
-1
and the heating temperature of 1100 ~ 1200 ℃
the thermal deformation temperature of 900 ~ 1050 ℃ X.
deformation amount of 20% ~ 65% . Through the observation of microstructure
the results showed that
The higher thermal deformation temperature and the larger the deformation amount
the more conducive to the occurrence of dynamic recrystallization. But the heating
temperature (≤1200℃ )had no significant effect on the dynamic recrystallization
