摘要： A process for producing a mirror-finished directional electric sheet having a high magnetic flux density by conducting the smoothening (mirror finishing) of a steel sheet boundary, which is necessary for achieving ultralow core loss, in a finish annealing furnace, which process comprises the steps of conducting decarburizing annealing, removing the oxide layer present on the surface of a steel sheet by pickling, and coating the resultant surface with an annealing/separating agent comprising a substance which does not react or difficulty reacts with SiO2 to conduct finish annealing. The core loss can be reduced by subdividing magnetic domains and applying tension coating. The finish annealing step can dispense with hydration time, so that it can be completed in a shorter time.
摘要翻译：在终轧退火炉中，通过对最终退火炉进行超低铁损的钢板边界的平滑化（镜面精加工）来制造具有高磁通密度的镜面方向性电路板的方法，该方法包括进行脱碳退火的步骤，通过酸洗除去钢板表面上的氧化物层，并用包含不与SiO 2反应或难以与SiO 2反应进行最终退火的物质的退火/分离剂涂覆所得表面。可以通过细分磁畴并施加张力涂层来减少磁芯损耗。完成退火步骤可以省去水合时间，从而可以在更短的时间内完成。
