Design Optimization of Pouring basin in the Shape Casting Process, M.Sc. Thesis Sharif University of Technology ; Davami, Parviz (Supervisor) ; Tavakoli, Rohollah (Supervisor)
Abstract
The pouring basin is a main part in the gating system. The formation of a vortical flow is a big problem occurs during the discharge of melt from the pouring basin. The vortex formation can enter the floating slag and inclusion into the mold. In the case that the vortex is more stronger, a fully air core to the sprue forms and leads to entraining of the air to the mold. These phenomena can decrease the casting quality significantly. Therefore preventing of the vortex is necessary to produce a sound cast. In this study the mechanism of vortex formation is investigated and several solutions are presented to avoid its detrimental effects. For this purpose discharge of a tank is simulated...
