| Abstract: | Effect of double cold rolling on magnetic properties and microstructure of 3.98%Si-0.71%Al non-oriented silicon Steel Sheets cast by twin-roll thin strip casting process were investigated. The results show that the structure of the thin strip is equiaxed crystal, the recrystallization is complete and normalizing has lesser effect on microstructure. Using both cold rolled and double cold rolled process, the microstructure is equiaxed grain after final annealing. The average grain size of annealed sheet in double cold rolled specimen was smaller than single stage cold rolled sheet. Double cold rolling process is helpful for iron loss and magnetic flux density. |
