METHOD FOR IMPROVING HIGH-SILICON STEEL PREPARATION AND PROCESSING CAPABILITY BY UTILIZING HIGH-ENERGY ELECTRICAL PULSE

摘要

A method for improving high-silicon steel preparation process capability by utilizing a high-energy electrical pulse. The silicon content in the high-silicon steel accounts for 4% to 7% (percent by mass), and the balance is iron, microelement boron and unavoidable impurity elements. During high-silicon steel sheet and strip plastic processing, a high-energy electrical pulse is applied to a deformation region, the frequency of the electrical pulse being 60 to 300 Hz, the pulse width being 10 to 300 μs, and the peak current density being 20 to 500 Α·mm-2; during a deformation process, the application of the high-energy electrical pulse significantly reduces the deformation resistance of the high-silicon steel sheet and strip and improves the plasticity of the high silicon steel sheet and strip.
