Sand inclusion
Webb6. Inclusion (or) sand inclusion: Sand particles present inside the casting is called as casting or sand inclusion. It is because of sand erosion taking place during casting. This is due to the turbulent flow of molten metal in the gating system. Using a gating system for filling the cavities in loose sand molds. Webb29 juni 2016 · General defects in gray cast iron often include pores, sand inclusions, oxide defects. Oxide defects in the microstructure of these alloys can be classified as follows: (a) Oxides caused by slag. (b) Oxides caused by molten turbulence. These defects occur during filling of the mold cavity.
