采用硅钼竖炉、高压真空复合碳管电阻炉冶炼含有Ar、N2、CO气泡的钢样,并运用金相显微镜、扫描电镜以及能谱仪对钢样中Ar、N2、CO气泡及其周围组织进行了分析,重点研究了钢中Ar、N2、CO气泡的气体成分、界面化学成分、界面形貌、大小及其附带夹杂物等问题,意在弄清3种气泡在钢中的特征,并通过分析给出相应气泡的辨别依据,为生产提供理论支持。
The samples containing Ar, N2 and CO bubbles were smelted by the silicon-molybdenum shaft furnace and the high-pressure vacuum carbon nanotube resistance furnace. The microstructure of Ar, N2 and CO bubbles in and around the steel samples were analyzed by metallographic microscope, scanning electron microscope and energy dispersive spectrometer Organization, analyzes the gas composition, interfacial chemical composition, interface morphology, size and incidental inclusions of Ar, N2 and CO bubbles in steel, and aims to clarify the characteristics of the three kinds of bubbles in steel, And through the analysis gives the basis for the identification of the corresponding bubbles for the production to provide theoretical support.
