Nailed It! Measurement of Steel Surface Velocity in the Tundish With Open Eyes (Room 407)

08 May 19
8:30 AM - 9:00 AM

Tracks: Continuous Casting

Open eyes in the tundish during continuous casting expose liquid steel to ambient atmosphere, resulting in the formation and growth of oxide inclusions, which compromise steel cleanliness. This is further complicated in a twin-strand caster, which does not always cast at balanced steel throughput rates. As a result, inclusions may preferentially move toward one strand over another. Trials were conducted at a slab caster tundish to form open eyes and measure steel surface velocity in the tundish using the nail dip technique. Results were compared with CFD simulations and water model experiments conducted at the University of Toronto's Process Metallurgy Research Labs.
