Application of Tanks-in-Series Model to Characterize Non-Ideal Flow Regimes in Continuous Casting Tundish

This study describes a new tanks-in-series model for analyzing non-ideal flow regimes in single-strand tundish. The tundish was divided into two interconnected tanks, namely an inlet tank and outlet tank. A water experiment carried out to separately measure the residence-time distribution (RTD) of tanks. Drift beads were adopted simulate non-metallic inclusions molten steel. Dead volume fraction evaluated by measured RTD curves. ratio between mixed plug proposed as criterion evaluate inclusion removal. In tank, higher preferred effectively release turbulent kinetic energy enhance collision growth. facilitate removal flotation. optimal positions weir recommended based on analysis from results experiments. theoretical equation derived model, providing good fitting function analyze experimental data. confirmation test performed applying computational fluid dynamics simulations liquid steel real
