综述了当前国内锰系铁合金存在的主要质量问题,提出了杂质的去除方法。若锰系铁合金中的杂质在炼钢过程中不能有效去除,或者超过钢种的要求范围,且在炼钢末期时加入的,这时锰系铁合金才需要精炼。未来的锰系铁合金分为普通产品和纯净产品,纯净锰系铁合金通过锰硅铁合金和中、低碳锰铁炉外精炼获得。
The main quality problems existing in domestic ferro-manganese alloys are summarized, and the methods for removing impurities are proposed. If the manganese ferroalloy impurities in the steelmaking process can not be effectively removed, or exceed the required range of steel, and joined in the late steelmaking, when the manganese-based ferroalloy needs refining. The future of manganese ferroalloy is divided into ordinary products and pure products, pure manganese ferroalloy by ferrosilicon ferroalloy and medium and low carbon ferromanganese furnace refining obtained.
