CN205069256U 一种电工钢板材 有权

一种电工钢板材
摘要：
本实用新型提供一种电工钢板材，该电工钢板材包括板状电工钢基体、所述基体表面的刻痕沟槽和所述刻痕沟槽表面分布的含有水化硅酸钙相和水化硅酸镁相的基体层，所述基体的厚度为0.1～2mm，所述水化硅酸钙相和所述水化硅酸镁相的直径为1～100nm，所述水化硅酸钙相和所述水化硅酸镁相的总面积占所述刻痕沟槽表面积的20～80％，所述水化硅酸钙相和所述水化硅酸镁相的体积比为1:1～1:10。本实用新型的水化硅酸钙相和水化硅酸镁相对于沟槽附近区域的拉应力或位错具有强烈的钉扎效应，使激光刻痕产品经退火处理后铁损降低效果不会消失，保持原有的磁性能。
摘要（英）：

The utility model provides an electric steel sheets and strips material, this electric steel sheets and strips material package rubbing board form electrical sheet base member the nick slot of matrix surface with nick grooved surface distributes contains the base member layer of hydrated calcium silicate congruence aquation magnesium silicate looks, the thickness of base member is 0.1-2mm, the hydrated calcium silicate congruence the diameter of aquation magnesium silicate looks is 1-100nm, the hydrated calcium silicate congruence the whole area of aquation magnesium silicate looks accounts for nick grooved surface long -pending 20-80%, the hydrated calcium silicate congruence the volume ratio of aquation magnesium silicate looks is 1: 1-1: 10. The utility model discloses a near hydrated calcium silicate congruence aquation magnesium silicate regional tensile stress for the slot or dislocation have strong pinning effect, make laser nick product iron loss behind annealing process reduce the effect and can not disappear, keep original magnetic property.
