평형주형형 박슬라브 연속주조에서 노즐 형태가 공정에 미치는 영향에 대한 수치 모사 연구 = Materials Processing:Numerical Simulation on the Effect of Nozzle Shape in the Process of Parallel Mold Type Thin Slab Casting

다국어 초록 (Multilingual Abstract)

In thin slab continuous casting process, the submerged entry nozzle (SEN) design is the prime controlling factor of the flow patterns of liquid steel which has an important effect on the surface and internal quality of steel produced. Four SENs were designed with different port angles and sleeve lengths. Solving three-dimensional thermo-fluid-dynamics by the control volume method with body-fitted coordinates system, horizontal velocity on the meniscus and temperature distribution were compared for each SEN. The solidified shell thickness was also investigated at each case. And also the inclusion path was traced to see the tendency of inclusion removal.
