摘要

在斯洛文尼亚，用于无取向硅钢片的铁硅铝合金是以可持续的方式设计和生产的。废铁被回收利用，因此二氧化碳排放量大大减少。然而，基于二次冶金的可持续技术有许多局限性。钢液中无法有效去除的杂质会增加材料在加工和使用过程中的复杂性。铜（Cu）是污染最严重的元素之一。在本综述中，重点讨论了在某些铁-硅-铝合金冶金加工的特定步骤中与铜杂质有关的现象。已确定的与铁硅铝无取向电工钢中铜的存在有关的某些技术阶段的效率挑战可能会激励进一步的（跨）学科基础或应用研究。为了实现欧盟的既定目标，并在 2050 年前实现气候中和，采用可持续循环经济方法生产的硅电工钢必须被视为欧盟的战略材料。

SUSTAINABLE AND STRATEGIC SOFT-MAGNETIC Fe-Si-Al ALLOYS PRODUCED BY SECONDARY METALLURGY

In Slovenia, Fe-Si-Al alloys for non-oriented, silicon-steel sheets are designed and manufactured in a sustainable manner. Ferrous scrap is recycled, and, therefore, CO2 emissions are greatly reduced. However, sustainable technologies based on secondary metallurgy have many limitations. Impurities that cannot be effectively removed from the steel melt increase the complexity of the material’s behavior during processing and use. One of the most contaminating elements is copper (Cu). In this review, the focus is on phenomena related to the Cu impurity during the specific steps of the metallurgical processing of selected Fe-Si-Al alloys. The identified challenges concerning the efficiency of some technological phases related to the presence of Cu in Fe-Si-Al, non-oriented electrical steels might motivate further (inter)disciplinary research, basic or applied. In order to follow the set goals of the EU and achieve climate neutrality by 2050, silicon electrical steels produced with sustainable circular-economy approaches must be recognized as a strategic material for the EU.
