以普通硅钢和硅铁合金为原料，采用包覆浇铸法制备具有三层结构的高硅电工钢铸坯，之后结合传统的轧制工艺和扩散退火工艺获得了6.5% Si电工钢复合板，利用光学显微镜和扫描电镜研究了其显微组织和硅元素的分布，并对其磁性能进行了测试。结果表明：采用上述工艺方法成功制备出了0.5 mm厚的电工钢复合板；经1 200℃×75 min扩散退火后，电工钢复合板中的硅元素发生了完全扩散，复合板由三层结构变成单层结构，整体硅元素质量分数约为6.5%；6.5% Si电工钢复合板的铁损P_1.5/50为2.68~2.72 W·kg^-1，磁感应强度B₈为1.370~1.378 T、B₅₀为1.610~1.625 T；与0.34 mm厚的Fe-6.5% Si合金相比，复合技术制备的6.5% Si电工钢复合板的磁感应强度较高，但铁损也略高。
