摘　　要：对浸入式水口从不同位置分别进行取样,借助扫描电镜和能谱仪,观察不同位置的结瘤物宏观形貌和微观结构,并分析各个位置结瘤物的微观结构和成分组成。研究表明,浸入式水口结瘤物主要分为黄褐色结瘤物、白色结瘤物和冷钢3种;其中,黄褐色结瘤物的主要成分为Al_(2)O_(3)、Fe以及少量FeO和SiO_(2)组成的混合物,白色结瘤物主要成分为Al_(2)O_(3)。Take samples from different positions of the immersion nozzle,observe the macroscopic morphology and microstructure of the nodules at different positions with the help of scanning electron microscope and energy spectrometer,and analyze the microstructure and composition of the nodules at each position.Studies have shown that the immersion nozzle nodules are mainly divided into yellow-brown nodules,white nodules and cold steel.Among them,the main components of the yellow-brown nodules are a mixture of Al_(2)O_(3),Fe and a small amount of FeO and SiO_(2).The main component of white nodules is Al_(2)O_(3).
