초록

Steel is one of the most widely used metals for various industries in the world. Over 95% of steels in the world is manufactured from continuous casting processes. During continuous casting, there are many phenomena including fluid flow, heat transfer, solidification, particle transport, etc. in mold regions. Molten steel continuously flows into the mold through the nozzle, and generates asymmetric flow pattern. The asymmetry of flow behaviors affects the behavior of surface slag/molten steel interface on the top of molten steel pool. These phenomena are influential on the quality of final steel products. This work investigates the asymmetric flow and the top surface behaviors in mold region with a slide-gate nozzle during continuous casting of steel slabs, by applying lab-scale water model experiments.
