摘要
钢铁冶炼过程中脱氧问题是决定钢材质量的关键环节。在对氧化物冶金可利用的脱氧产物的研究中,Ti、Mg对钢的复合脱氧形成的氧化物夹杂更加分散,具有很好的脱氧效果。针对Al-Ti-Mg复合脱氧钢,从合金的制造、夹杂物形成机理、晶粒结构、力学性能、夹杂物对铁素体形核的影响等方面的研究进展进行了综述,提出了当前Al-Ti-Mg复合脱氧技术还处于未完善阶段,仍存在许多问题亟待解决,并为未来冶金领域研究工作者进一步探索与研究提供了方向。
Deoxidation in steel smelting process is the key process to determine the quality of steel.In the research of the deoxidation products which can be used in the oxide metallurgy,Ti and Mg oxide inclusions formed by the compound deoxidation of the steel are more dispersed.In this paper,alloy manufacturing,inclusion formation mechanism,crystal structure,mechanical properties and the effect of inclusions on the ferrite nucleation in Al-Ti-Mg composite deoxidized steel are summarized.The problems to be solved in Al-Ti-Mg composite deoxidized steel are put forward,and the direction for researchers to further explore and research field of metallurgy are provided.
