Example Embodiment
[0033] Example 1
[0034] In this embodiment, the method for preparing rotating cubic dual-oriented silicon steel based on thin strip continuous casting is carried out as follows:
[0035] Smelt molten steel according to the set composition, and its composition by weight percentage is: C 0.01%, Si 1.6%, Mn 0.0025%, V 0.03%, Al 0.0044%, P 0.0075%, S 0.002%, N 0.0016%, O 0.0013% , Nb0.0011%, Ti 0.0018%, the balance is Fe;
[0036] Thin strip continuous casting process: the molten steel enters the tundish through the gate, the preheating temperature of the tundish is 1200℃, the superheat is controlled to 60℃, the molten steel enters the thin strip continuous casting machine through the tundish to form a casting strip, and the casting speed is controlled to 50m / min, control the height of the molten pool to 140mm, and control the thickness of the casting strip to be 2.8mm;
[0037] After the cast strip comes out of the roll, it is naturally cooled to the hot rolling mill under inert atmo...
