【 摘 要 】

Minimization of intermixing length during continuous casting of steel is a crucial step towards higher productivity and yield of a continuous casting technology. For such a complex mass transfer problem, physical simulation using scaleddown water models might become indispensable tool to quantify the liquid steel parameters in the tundish. In this paper, such an advanced, water-based model of tundish from Železiarne Podbrezova, a. s. is used to model the intermixing process of two consecutive heats with different chemical composition. Obtaining the non-standard F-curves while manipulating the liquid level and the casting speed simultaneously gave us a valuable insight into the process of intermixing and allowed us to make preliminary conclusions on the intermixing optimization problem.
