Abstract Scope To increase on both of the capacity and defectless thin slab production, the submerged entry nozle (SEN) structure design and technology parameters of continuous casting were modified by studying the fluid flow and temperature distribution characteristics using physical and numerical simulation method. The results showed that the mold level fluctuation was strongly dependent to caster speed, and the average wave height exceeded 7mm while the casting speed increased from 2.0 to 2.2 m/min for the section of 150mm×1540mm. Compared to increase the angle of side-outlet or submerged depth of the SEN, the increase of the bottom port diameter of the three-port SEN was more effective on modification of level fluctuation although the maximal surface temperature was slightly decreased. Practical application also showed the effective performance of SEN design on improvement of the slab surface quality.
