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。
The nozzle clogging of Ti-IF steel were analyzed by SEM.The results showed that nozzle clogging was 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,the analysis found a lot of Ti-Al-O composite inclusion and Al2O3 inclusion in the tundish steel.The Ti-Al-O composite inclusion and Al2O3 inclusion were the main reason for the nozzle clogging.
