软磁材料的磁性能和表面质量的优劣,不仅决定于材料的主要化学成分、杂质元素和气体、夹杂物,而且受加工过程诸因素影响。人们为了提高材料的磁性能,改善材料表面质量,曾做了大量试验研究工作。近年来我所生产的1J79高磁导率合金,虽然磁性能较高且稳定,但是因生产过程诸因素影响,导致合金冷轧带材表面出现较多气泡, Soft magnetic materials, magnetic properties and surface quality of the pros and cons, not only depends on the material’s main chemical composition, impurity elements and gases, inclusions, but also by the processing of various factors. People in order to improve the magnetic properties of materials to improve the quality of the surface of the material, has done a lot of experimental work. In recent years, I produced 1J79 high permeability alloy, although the magnetic properties of high and stable, but due to the production process of various factors, resulting in alloy cold rolled strip surface appear more bubbles,
