Study of Microstructure and Magnetic Properties on High-Silicon Steel Composite Sheet

Abstract:

High-silicon composite casting blank with the silicon content of 12wt% in core layer and with the silicon content of 3wt% in coating layer was fabricated by composite casting. The high-silicon steel composite sheet with smooth surface and good shape can be obtained by hot rolling and warm rolling. After high temperature diffusion and pickling process, the composite sheet with thickness of 0.44mm and homogeneous silicon content of 5.8wt.% could be achieved finally. The test results of magnetic properties show that the magnetic induction intensity B₅₀ and iron loss P_15/50 are 1.778T and 2.892w/kg respectively. It implies that the high-silicon steel composite sheet with high magnetic induction and low iron loss can be prepared by composite casting and rolling process.
