Description

Flow in the tundish region during the continuous casting of steel can influence many important phenomena, especially removal of the non-metallic inclusions. If they are not removed from the steel melt during its processing, it can reduce the quality of the finished steel product. Therefore, in this study, the complex numerical modelling in the CFD programme ANSYS Fluent was used for detection of non-metallic inclusions removal from the steel during the flowing in a five-strand asymmetric tundish with different configuration of the impact pad. The distribution of inclusions was ranging from 2 µm to 100 µm and density from 2500 to 3500 kg·m−3. Inclusion removal efficiency was used for evaluation of steady state steel flow character depending on internal configuration. Based on the results obtained from modelling, the main findings and recommendation for optimal conditions of steel flow in tundish were formulated.
