摘要
非金属夹杂物控制是一直是洁净钢生产的重要课题。近年来,镁在钢中应用的焦点已由传统的夹杂物改性演变为微合金化领域的研究,实现了从冶金到材料视角的转变。综述了镁在钢中应用的国内外研究现状,分别从洁净度控制、氧化物冶金、凝固组织细化、微合金钢铸坯裂纹控制等几个方面阐述了镁合金化的优势,并对镁洁净钢可能拓展的领域和方向进行了分析与展望。
Non-metal inclusion control has always been an important subject in clean steel production.In recent years,the focus of Mg application in steel has changed from the traditional modification of inclusions to the microalloying.This paper reviews the research status of Mg application in steel at home and abroad,represents the advantages of Mg from several aspects,such as cleanliness control,oxide metallurgy,solidification microstructure refinement,slab crack control,etc.The possible development fields and directions of magnesium clean steel are also analyzed and prospected.
