| Abstract Scope |
The influence of different continuous casting process parameters (casting speed, the port angle and the depth of submerged entry nozzle) on the shear-induced slag entrapment was investigated to address the influence of the process parameters on the surface quality during the production of 304 stainless steels. On this basis, a three-dimensional coupled finite element model for molten steel flow-thermal model was established to evaluate effects of typical casting parameters using the definition of critical slag entrapment velocity as criterion. Numerical simulations demonstrated that the maximum surface velocity improved from 0.29 m/s to 0.37 m/s with increasing casting speed from 1.0 m/min to 1.2 m/min, which intensifies meniscus turbulence. However, the increase of the port angle and the depth of submerged entry nozzle (SEN) effectively reduced the maximum surface velocity to 0.238 m/s and 0.243 m/s respectively, with simultaneous improvement in slag-steel interface temperature. |
