In order to alleviate the impact of flow jet of nozzle side-ports on solidifying shell and easy to use the sideport nozzle to the mold for casting square billet with smaller cross section
a design idea of submerged entry nozzle ( SEN) with flabelliform side-ports is advanced. The characteristics of flow field and temperature field in mold for casting 200 mm x 200 mm billet with straight channel nozzle
rectangular side-ports nozzle and flabelliform side-ports nozzle are analyzed and compared by using three dimension math model of fluid flow and heat transfer in mold. Research results show that the side-ports nozzle is available to reduce the impact depth of flow jet
improve the inclusions floating up
and increase the temperature and activity of liquid at meniscus and favorable to smelt slag; the flow from flabelliform side-port is more disperse
so the effect of impact on solidifying shell is sharply decreasing.
