Mould characteristics of Azare foundry sand

This paper investigates the mould characteristics of Azare foundry sand such as moisture content, bulk density, flowability, permeability, shatter index, green strengths, dry strengths, hot strengths, thermal linear expansion and refractoriness. A thorough review of literature was made and comparison made between the existing values and values obtained experimentally. Based on the experimental results, Azare foundry sand is essentially very good for non-ferrous foundries. Also, based on the closeness of the characteristics of the Azare foundry sand to the existing characteristics of foundry sand used in cast iron foundries, practical trials carried out on a smail cast iron casting (crusher bearing-housing) showed an excellent surface finish.
