MgO for oriented silicon steel separant, separant comprising same, oriented silicon steel having film formed therefrom, and manufacturing method
The invention provides magnesium oxide for an oriented silicon steel separant, the magnesium oxide comprises 40-80 wt% of magnesium oxide fine particles with a particle size of less than 7 [mu] m and 20-60 wt% of magnesium oxide coarse particles with a particle size of 7-100 [mu] m, and the CAA40% of the magnesium oxide is 100-170s. By controlling the particle size of MgO particles for the oriented silicon steel separant, the air permeability of the separant can be improved, so that the possibility of oxidation of a steel plate is reduced, the forsterite film defect of the steel plate is reduced, and the problems of coil loosening and coil collapse caused by incomplete film covering, crystal exposure defect and insufficient friction force between steel plates are avoided; and thus, the uniformity of the forsterite film is improved. In addition, the MgO is stable in performance, not prone to hydration and suitable for forming a uniform forsterite film on the oriented silicon steel plate.
本发明提供了取向硅钢隔离剂用氧化镁，所述氧化镁包含40‑80重量％的粒径小于7μm的氧化镁细颗粒和20‑60重量％的粒径为7‑100μm的氧化镁粗颗粒，所述氧化镁的CAA40％为100‑170s。本发明通过控制取向硅钢隔离剂用MgO颗粒的粒径，可以提升隔离剂透气性，从而降低钢板氧化的可能，还降低了钢板的镁橄榄石膜缺陷，避免例如膜覆盖不完全、露晶缺陷、和钢板间摩擦力不足导致的松卷、塌卷的问题，并由此改善了镁橄榄石膜的均匀性。此外，本发明的MgO性能稳定，不易水化，适于在取向硅钢板上形成均匀的镁橄榄石膜。
