Abstract:The horizontal single belt casting (HSBC) incorporating a single-impingement feeding system was simulated with an improved numerical model. Physical experiments were carried out on the pilot-scale caster for validation. The results show that the meniscus turbulence neither comes from the tundish region, nor from the impingement between the melt and the moving belt. It is the moving belt that gives rise to this high turbulence region, and this region can stir the melt near the meniscus. The feeding system studied and the moving belt give rise to a buffer region, which can optimize casting parameter variations, especially melt depth changes in the tundish. The temperature change rate of the bottom surface of the strip is around 4 times faster than that of the upper surface.
Key words: horizontal single belt; transport phenomenon; strip casting; numerical simulation; meniscus
