Continuous Casting
Tundish open eye (TOE) occurs during inert gas shrouding of liquid steel during continuous casting. TOE affects steel cleanliness and can be mitigated by comprehensive troubleshooting using plant trials, analytical models, water model experiment, and computational simulations. During the plant trials, TOE formation, morphologies and size variation at AMD’s tundish were captured using a video camera. In the water model, the TOE was visualized using a high-speed camera, high-definition videography and particle image velocimetry. Complementary computational fluid dynamic simulations were also performed. Using this integrated approach, the TOE formation mechanism has been understood, root-cause analyses have been performed, and solution strategies have been proposed to mitigate its effects.
