摘要/Abstract

摘要： 通过扫描电镜对Ti-IF钢水口堵塞物进行分析，研究表明水口堵塞物中分为2层，其中靠近水口耐火材料部分反应层为Ti-Al-O复合夹杂物和Al₂O₃夹杂物的混合物，靠近钢水的堆积层为Al₂O₃夹杂和冷钢的混合物。利用扫描电镜对浇铸炉次的中间包钢水中的夹杂物进行了分析，通过分析发现中间包钢水中含有大量的Ti-Al-O复合夹杂物和Al₂O₃夹杂，中间包钢水中Ti-Al-O复合夹杂物和Al₂O₃夹杂是水口堵塞的主要原因。

Abstract: The nozzle clogging of Ti-IF steel were analyzed by SEM, through the study of nozzle clogging is divided into two layers, including near the nozzle refractory material part reaction layer for Ti-Al-O composite inclusion and Al₂O₃ inclusion mixture, near steel accumulation horizon for Al₂O₃ inclusion and cold steel mixture. The inclusions of steel in tundish were analyzed by SEM, through the analysis found that a lot of Ti-Al-O composite inclusion and Al₂O₃ inclusion in the tundish steel. The Ti-Al-O composite inclusion and Al₂O₃ inclusion is the main reason for the nozzle clogging.

Key words: Ti-IF steel, nozzle clogging, Ti-Al-O composite inclusion
