【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。
[Abstract]:Deoxidation is the key to the quality of steel in the process of iron and steel smelting. In the study of the deoxidized products available in oxide metallurgy, the oxide inclusions formed by the composite deoxidation of steel are more dispersed and have good deoxidation effect. In this paper, the research progress of Al-Ti-Mg composite deoxidized steel from the aspects of alloy manufacture, inclusions formation mechanism, grain structure, mechanical properties and the effect of inclusions on ferrite nucleation are reviewed. It is pointed out that the present technology of Al-Ti-Mg composite deoxidation is still in the imperfect stage, and there are still many problems to be solved urgently, which provides a direction for further exploration and research of metallurgical researchers in the future.
