Abstract
)In order to simulate the mold filling and solidification of the outer shell of large work rolls being cast byhorizontal centrifugal casting, the shallow water equations were adopted to solve the 2D average flowdynamics of the melt spreading inside the cylindrical mold. The model accounts for centrifugal force,Coriolis force, shear force, gravity and convective and diffusive energy transport. The solidification frontwas tracked by fulfilling the Stefan condition. Radiative and convective heat losses were included fromboth, the free surface and the outer wall of the mold. By introducing a stochastic factor to account for theirregular filling jet behavior an uneven spreading of liquid from the center of the mold towards the extrem-ities was predicted. Thus, the formation of the first solid layer also happens unevenly. However, when themold is covered everywhere with a solid layer, the solidification rate decreases and further filling increasesthe height of the liquid layer. With increase liquid height the amplitude of the free surface waves alsoincreases.KEY WORDS: horizontal centrifugal casting; work roll; shallow water equations; Coriolis force; Stefan con-dition; mold deformation.
