Abstract: The influence of the submerged entry nozzle(SEN) on the flow field and heat transfer of the 550mm×700mm super-large cross-section rectangular bloom mold was studied by using the ANSYS Fluent finite element software. The research results showed that the adoption of the double-hole type SEN was more conducive to the upward floating of inclusions and was less likely to cause slag entrapping on the liquid surface. When the inclination angle of the side hole was 60°, the flow velocity at the meniscus was 0m/s, which was less likely to cause slag entrapment, and was more conducive to the upward floating of inclusions. As the insertion depth of the SEN increased, the probability of slag entrapment on the liquid surface was reduced, but the chance of inclusions floating up was also decreased. Taking all factors into account, the insertion depth of the SEN was preferably 300mm. |
