Development of Submerged Entry Nozzles that Resist Clogging

摘要

Accretion formation and the associated clogging of SEN's is a major problem for the steel industry leading to decreased strand speed, premature changing of SEN's or strand termination and the associated reductions in productivity, consistency, and steel quality. The program to evaluate potentially clog resistant materials was initiated at the University of Missouri-Rolla. The main objective of the research effort was to identify combinations of steelmaking and refractory practices that would yield improved accretion resistance for tundish nozzles an submerged entry nozzles.
