Abstract |
|
In this paper casting defects was studies due sand properties like permeability, grain size, moisture content and molten metal pouring temperature. Pure Aluminium metal has taken to study defects like porosity, shrinkage, and blow holes. In order to minimize these defects, process parameters were studied like Sand – Grain Fineness Number of sand, permeability, Pouring Temperature. Sieve shaker, Permeability meter, Muller machine, Scanning Electron Microscope was used to study the surface defects. Since permeability of sand is function of the degree of ramming, so it is very important to prepare the specimen according to standard conditions. A laboratory sand rammer was used along with a specimen tube to get standard ramming conditions. |
