摘　　要：铁合金由于其在炼钢工业中不可或缺的作用而变得越来越重要,随着市场对钢材质量的需求大幅提高,因铁合金中的杂质直接影响钢材质量,进一步凸显了铁合金品质的重要性.为了更好地理解铁合金中主要微量元素和夹杂物添加至钢液中的变化及其在钢液中的行为,本文分析了铁合金的应用及其发展趋势,重点概述了铁合金中的一些微量元素和杂质对钢中夹杂物特性的影响,确定了不同铁合金中可能存在的有害夹杂物.总体而言,铁合金中夹杂物对钢的洁净度有如下影响:①锰铁和锰硅合金中的MnO、MnS、MnO-SiO_(2)-MnS夹杂物对钢材质量有阶段性影响.②锰铁和钼铁合金中大尺寸SiO_(2)夹杂物(200μm)对钢材的洁净度影响尚不清晰,添加硅铁合金前需考虑Al、Ca含量的影响,最后对铁合金未来发展提出了建议.Ferroalloys have become increasingly important due to their indispensable role in the steelmaking industry.With the significant increase in market demand for steel quality,impurities in ferroalloys directly affect steel quality,further highlighting the importance of ferroalloy quality.In order to better understand the changes of major trace elements and inclusions added to molten steel in ferroalloys and their behavior in molten steel,this article analyzes the application and development trends of ferroalloys,focusing on the influence of some trace elements and impurities in ferroalloys on the characteristics of inclusions in steel,and identifies potential harmful inclusions in different ferroalloys.Overall,inclusions in ferroalloys have the following effects on the cleanliness of steel:①MnO,MnS,and MnO-SiO_(2)-MnS inclusions in ferromanganese and ferromanganese-silicon have a phased impact on the quality of steel.②The effect of large-sized SiO_(2)inclusions(200μm)in ferrosilicon and ferromolybdenum on the cleanliness of steel is not yet clear.Before adding ferrosilicon,the influence of Al and Ca content needs to be considered.Finally,this article proposes suggestions for the future development of ferroalloys.
