摘要

采用扫描电镜和X射线衍射法

分析了EAF-AOD-VOD精炼409L不锈钢(%:0.009～0.011C、11.36～11.63Cr、0.15～0.22Ti、0.0074～0.0112N)连铸水口结瘤的物相。结果表明:水口结瘤中的物相主要有TiO

和金属。喂钛线后吹氩搅拌过强时

由于钢水的二次氧化会显著增加钢中TiO

夹杂物的数量

导致结瘤层明显变厚。喂钛线后采用吹氩弱搅拌

能尽可能排除钢中TiO

夹杂物;同时应避免连铸时铸流二次氧化

从而减少水口结瘤的发生。

Abstract

The phases of clogging of nozzle during concasting of 409L stainless steel(0.009～0.011C

11.36~ 11.63Cr

0. 15~0.22Ti

0.0074～0.0112N)melted by EAF-AOD-VOD refining has been analyzed by scanning electron microscope(SEM)and X- ray diffraction method. The results indicated that phases of clog in nozzle consisted of TiO₂ and metal;and with over strong argon stiring after titanium wire feeding the amount of TiO₂ inclusion obviously increased due to reoxidization of molten steel

it led to clog being obvious thickening. The clogging of submerged entry nozale decreased by using soft argon stiring after titanium feeding to remove TiO₂ inclusion in molten steel and avoiding reoxidization of cast strand.
