无取向硅钢磁性能提升技术进步及其发展动向

无取向硅钢的磁性能主要取决于铁素体的晶粒尺寸、晶体织构和钢中的夹杂物。通过合适的化学成分设计以及采用适宜的夹杂物控制技术,可以获得最佳的夹杂物控制效果,使其纯净度大幅度提高或者无害,最终获得磁性能优良的高级别无取向硅钢。同时,为满足节能、环保、高效需求,无取向硅钢正朝着节能降耗、环境友好以及多功能、高效率、易加工等方向发展。

Techniques Progress and Development Trends of Magnetic Property of Non-oriented Silicon Steel

The magnetic properties of non-oriented silicon steel mainly depend on the grain size of ferrite, the crystallographic texture, and the inclusions in the steel. The optimum inclusion control effects can be obtained through a suitable chemical composition design and an appropriate inclusion control technique, and then the liquid steel will get be clean or the inclusion will get be harmless, finally the excellent magnetic property of the non-oriented silicon steel can be obtained. Meanwhile, in order to meet the energy-saving, the environmental protection and the high efficiency, the non-oriented silicon steel increasingly develeps to the direction of energy-saving, low consumption, no polution, multifunction, high effciency and easy processing and so on.
