摘要

摘要根据对使用碱土金属（AEMs）多组分含铝改性剂进行结构钢钢包加工的理论和实验室研究结果，确定了使用 Ca-Al 和 Ba-Al 复合物替代标准技术（铝脱氧和硅钙改性）的热力学和技术优势。使用复合微晶合金 Fe-Si-Al-Ca-Ba，可以将钢的脱氧和精炼过程结合起来，减少非金属夹杂物（NI）对金属的污染，降低脱氧剂的消耗，缩短钢包中钢水的处理时间。

On Joint Deoxidation and Refining of Steel with Complex Alloys

Abstract

Based on the results of theoretical and laboratory studies of structural steel ladle processing with multicomponent aluminum-containing modifiers with alkaline earth metals (AEMs), the thermodynamic and technological advantages of using Ca–Al and Ba–Al complexes instead of standard technology (deoxidation with aluminum and modification with silicocalcium) have been identified. The use of a complex microcrystalline alloy Fe–Si–Al–Ca–Ba makes it possible to combine the processes of deoxidation and refining of steel, reduce metal contamination with non-metallic inclusions (NI), reduce deoxidizer consumption and the duration of melt processing in the ladle.

期刊介绍： Steel in Translation is a journal that represents a selection of translated articles from two Russian metallurgical journals: Stal’ and Izvestiya Vysshikh Uchebnykh Zavedenii. Chernaya Metallurgiya . Steel in Translation covers new developments in blast furnaces, steelmaking, rolled products, tubes, and metal manufacturing as well as unconventional methods of metallurgy and conservation of resources. Papers in materials science and relevant commercial applications make up a considerable portion of the journal’s contents. There is an emphasis on metal quality and cost effectiveness of metal production and treatment.
