Determination of recycle potential in waste green foundry sand through spatiotemporal analysis of sand mold

Green sand is used for making molds to obtain the desired casting in foundries. The process is associated with solidification of molten metal that results in the evolution of the latent heat of fusion. The clay used for binding purpose is decomposed to various forms depending on the local temperatur...

The process is associated with solidification of molten metal that results in the evolution of the latent heat of fusion.
