Methods for improving the magnetic properties of 3% non-oriented silicon steel were investigated. The thickness of samples was reduced to 0.1 mm by cold-rolling, and they were subsequently annealed in an argon gas atmosphere under various annealing conditions (annealing temperature, holding time, heating rate, and cooling rate). The obtained minimum iron loss was W15/50 = 2.38 W/kg, the coercive force was Hc=38 A/m, and the magnetic induction at 800 A/m was B8 = 1.69 T. The sample annealed under the optimum annealing conditions showed a dual-axis-like torque curve and had a high proportion of (100) plane texture.
