Abstract:

In the casting technology, defect free casting had been the primary goal since the inception of the technology. However in the present casting ground, emphasis on the exact and defect free casting has got greatly improved due to energy saving, environmental and economy considerations apart from the stringent product quality standard requirements. In order to achieve this level, computer simulation is certainly needed. FEM based simulation software is used to find solidification related defects specially shrinkage porosity very precisely. In the present work ANSYS, an FEM based versatile software has been used for hot spots identification in LM 06 dumbbells of different volumes in sand casting. The feeders have been designed and optimized by ANSYS 12.0 design optimizer tool & experiment. ANSYS has been used for transient thermal analysis and then optimization process has been performed. Path of two feeder optimization for sand casting on ANSYS have been investigated. Conductive and convective heat transfer has been taken in to concern. The whole process is performed using traditional modulus approach also. The results are compared with experimental out comes. The comparison reveals that ANSYS optimizer provides enhanced results for casting having two feeders. It saves material and energy thus resulting into economy and environmental benefits. The effect of increase of cast volume over feeder yield has also examined.
