Numerical Simulation To Determine The Mould Filling Ability of Aluminum Alloy In Semi Solid Metal Processing

The term fluidity refers to the ability of a material to flow before it solidifies. This is a very significant factor which will determine the filling up of castings with complex and intricate shapes. Mould filling ability is a parameter that is used to determine the fluidity of a material in conventional castings. At semisolid temperatures the metal exists in the form of slurry. Hence fluidity of the material in the freezing range is very important. In the present study numerical simulations are carried out to determine the mould filling ability values and compared with casting fluidity parameter. The process parameters that were used in the simulations include billet temperature, ram speed and preheating of die.
