Experimental Research on Structure of Submerged Entry Nozzle Optimization for Slab Continuous Casting Mould

Qiang Yue

Abstract

Water model experiment for liquid steel flow in 210 mm×1300 mm slab continuous casting mould was employed. The influence of SEN structure on the steel flow in the mould was studied. The experimental results show that the new style SEN with concave bottom,round section,nozzle area ratio 1.9,dip angle 15° and the insert depth 72-108 mm could effectively improve flow field in the mould.
