| 摘 要： | 在现场进行中间包喂稀土实验,对水口结瘤样进行扫描电镜能谱分析和X-射线衍射分析。结果表明,在本实验条件下,水口瘤的主要组分为高熔点的稀土铝酸盐和凝钢;结瘤物是以钢中稀土与水口耐火材料相互作用形成的稀土铝酸盐为衬底,钢中的夹杂物在此基础上粘附烧结而形成。

| Abstract: | The industrial experiments of feeding RE into tundish were carried out and the typical blocked nozzle was cut and examined by means of SEM and X-ray diffraction. The results show that, under the experimental conditions, the main composition of blocked nozzle is RE aluminates and solidified steel; based on the substrate due to the reaction of RE in steel with the nozzle inner surface, the adhesion and sintering of inclusions in steel leads to the formation of blockage. |
