One of the major issues with submerged entry nozzles (SEN) used in the continuous casting process is alumina clogging. Alumina clogging occurs through a complex process in which several chemical reactions and physical interactions take place simultaneously. In order to prevent alumina clogging, suitable SEN application in terms of material chemistry as well as geometric design is essential. In this article, features of our four material types and two shape designs, which suppress clogging suppression, and their application results are described.
