Therefore, replacing the sand with alternate materials with better thermal conductivity, like steel balls improves the Heat transfer rate and reduces the solidification time of casting.
The medium steel shots mould material poses optimum permeability and packing, thereby the metallurgical and mechanical properties are found to be better than the finer and coarser steel shots mould materials. 4.
