Abstract

In this era of nano and precise accuracies we have great concern of productivity and finish in all levels of manufacturing which also includes casting process. In casting process we prepare casts, for this we require to carry the molten metal for which we require a device to carry i.e. ladle. A ladle is a component used for carrying the molten metal in the casting process and it undergoes a considerable heat loss. The molten metal gets solidified in the interior surface of the ladle and it is called as skull. To increase the productivity and yield rate we surely require an alternative solution, to reduce the skull formation in the ladle. In this paper it is focused to give theoretical and analytical information about the heat loss; problem of skull in the ladle. The Mathematical formulation used for solving of the problem is presented. It also presents the results graphically and comparisons will be laid out using MAT LAB software.

Keywords

Casting Process, skull reduction, ladle, solidification Phenomena, finite difference method.
