| Abstract: | The 0.5 mm×480 mm 50W1300 non-oriented electrical steel sheet 3t (0.04～0.06C,0.82～0.96Si, 0.35~0.40Mn,0.015~0.017P,0.014~0.019S) has been researched and produced by using 40 t LD converter ·180 mm×495 mm slab concasting-continuous rolling flow sheet. The molten steel temperature was controlled between 1650 ℃ and 1670 ℃ and the oxygen content in steel decreased from72.9×10-6to 22.9×10-6by argon blowing in ladle. The electromagnetism properties and mechanical properties of pilot produced cold rolled non-orientation eclectic steel all met 50W1300 requirement of GB/T2521- 1996 being suitable for manufacturing rotor of small motor. |
