Abstract: This paper presents a mercury model experiment and coupling numerical simulation with Reynolds time-average model on molten metal flow in the mold of continuous casting of slab. The purpose is to study the influence of a traveling magnetic field (electromagnetic stirring) on the metal flow in the mold. The result shows that, in the mold, the stirring force from the traveling electromagnetic field makes the molten metal form a horizontal circumfluence, leading to destroy of the originally regular circumfluence. In the whole mold, the flow is three dimensional and non-symmetrical. Furthermore, the traveling magnetic field strengthens fluctuation of meniscus. The fluctuation is stronger on the side where the nozzle flow is opposite to the electromagnetic force.

Key words: continuous casting of slab, electromagnetic stirring, molten metal flow, Reynolds stress model, traveling magnetic field
