摘要

对钢水中的 O 和 S 具有高亲和力的元素是炼钢过程中理想的脱氧剂和脱硫剂，其中 Ce 引起了人们的关注。本研究探讨了 1873 K 下 CaO-AlO1.5-CeO1.5 熔渣体系中硫的热力学性质。这些测量采用了一种使用 Cu 的化学平衡方法。测定了 CaO-AlO1.5-CeO1.5 体系中的硫化物容量，以显示脱硫能力；确定了在 CaO-AlO1.5-CeO1.5 体系中加入大量硫时的沉淀相；测定了 CaO-AlO1.5-CeO1.5 体系中 CaS 的溶解度。结果表明，该体系的炉渣可改善硫分布，同时降低钢中的铝浓度。

Thermodynamic Properties of Sulfur in the CaO–AlO1.5–CeO1.5 Slag System at 1873 K

Elements with a high affinity for O and S in molten steel are desirable as deoxidizing and desulfurizing agents in the steel refining process, and Ce has attracted attention. In this study, the thermodynamic properties of sulfur in a CaO–AlO1.5–CeO1.5 slag system at 1873 K are investigated. A chemical equilibrium method using Cu is employed for these measurements. Sulfide capacities are determined in the CaO–AlO1.5–CeO1.5 system to show desulfurization ability; the precipitated phases are identified when large amounts of sulfur are added to the CaO–AlO1.5–CeO1.5 system; the solubility of CaS in the CaO–AlO1.5–CeO1.5 system is determined. It is suggested that the slag of this system can improve sulfur distribution while reducing the Al concentration in the steel.

期刊介绍： steel research international is a journal providing a forum for the publication of high-quality manuscripts in areas ranging from process metallurgy and metal forming to materials engineering as well as process control and testing. The emphasis is on steel and on materials involved in steelmaking and the processing of steel, such as refractories and slags. steel research international welcomes manuscripts describing basic scientific research as well as industrial research. The journal received a further increased, record-high Impact Factor of 1.522 (2018 Journal Impact Factor, Journal Citation Reports (Clarivate Analytics, 2019)). The journal was formerly well known as "Archiv für das Eisenhüttenwesen" and "steel research"; with effect from January 1, 2006, the former "Scandinavian Journal of Metallurgy" merged with Steel Research International. Hot Topics: -Steels for Automotive Applications -High-strength Steels -Sustainable steelmaking -Interstitially Alloyed Steels -Electromagnetic Processing of Metals -High Speed Forming
