3-D modeling of the start-up phase of DC casting of sheet ingots
- VAW Aluminium AG, Bonn (Germany)
Three-dimensional transient simulations of the coupled fluid flow and heat transfer problem during the filling of the mold before the beginning of starting block movement have been used to investigate the influence of distributors and start-up programs on temperature and solidification front. As butt curl and possible hot tearing of the ingot are critically controlled by the temperature development of the metal in the mold, and the temperature itself depends on mold filling and start-up strategy, quality is strongly connected to appropriate metal distribution conditions in this early start-up phase. The calculated filling behavior and temperatures are discussed in dependency of parameters like distributor geometry or block shape. The simulations support the development of adjusted metal distribution systems.
