Computer simulation of the impact of pulling parameters on the process of continuous ingot casting

Cast ingot pulling speed significantly affects the nature of the resulting structure and the quality of the external surface. By introducing a variable ingot pulling algorithm allows to some extent to control the shape and location of the crystallization front and temperature field in the ingot cross section. The shape of the crystallization front, and its position relative to the crystallizer plays an important role in the continuous casting of iron ingots affecting the structure of the casting. In order to verify the impact of the ingot pulling algorithm to the shape and the location of the front of crystallization a series of simulations in ANSYS FLUENT 12 was carried out.
