Abstract:

Solidification of molten metal after being poured into a mould cavity is an important phenomenon in casting and is of great interest to physicists, metallurgist, casting engineers and software developers. A molten metal is poured at a very high temperature into refractory material sand at room temperature. During the solidification of casting in a mould, the heat transfer between casting and sand mould plays a vital role. It is a nonlinear transient phenomenon, posing a challenge in terms of modeling and analysis. It has been identified that the solidification process mainly governed by three parameters such as conductivity of sand, pouring temperature of molten metal and initial temperature of sand. Thus it becomes necessary to identify the most prominent parameter affecting the solidification out of the above mentioned. Experiments were conducted by simulation using ANSYS software to study the effect of these parameters on the heat transfer during solidification of casting. Thus experiments were planned using the strategy of design of experiments (DOE). Levels and ranges of input parameters were selected and then experiments were conducted. The results obtained with permutation and combinations of these parameters were analyzed by using Analysis of Variance (ANOVA), a statistical method to investigate the critical parameter affecting the heat transfer during the solidification process and their contribution.
