Using the planar flow casting method to prepare ultra-thin silicon steel ribbons is an eco-friendly and efficient production method. However, poor wettability between copper result in difficulties formability by which limits its application of ribbons. The process parameters are key factors affecting magnetic properties non-oriented ribbons, wheel speed determines solidification rate melt, has important influence on surface quality Therefore, this paper, effect microstructures Fe-3.0 wt %Si alloy systematically investigated. results indicate that as increases, grain size thickness gradually decrease. When 10 15 m/s, relatively flat. As deteriorates. were fragment with 35 m/s. Compared before annealing, induction B50 increased significantly iron losses P1.0/400 decreased sharply at 400 Hz after annealing. annealing m/s reaches 1.628 T corresponding loss 16.171 W/kg. lower lamination factor micropores may cause poorer properties.
