chromite sand properties

Chromite sand is the best sand medium for chilling metal. Chromite sand has the following physical and chemical properties: Melting point of 2150°C; Good thermal conductivity; Good resistance to thermal shock; Excellent resistance to metal penetration or burn-on; Resists slag attack; High dimensional stability Dry Strength -. However, due to mining restrictions and the fact that Chromite is not commonly found in crystallized form, it is not well-represented in mineral collections. Its basicity being close to neutral allows the use of a wide range of resin bonding systems and inorganic binders, it has a high refractoriness … • Chromite (FeCr2O4), a black, angular sand, is highly refractory and chemically unreactive, and it has good thermal stability and excellent chilling properties. Chromite ores contain 31 to 58% Cr 2 O 3 and 13 to 21.6% FeO. Sand is used to contain molten metal in a desired shape until the metal has solidified. However, thermal shock strength and effects of molten Al alloy on the casting process still remain to be explored. (5) The effect of the size of chromite sand on its refractoriness The size of chromite sand can significantly affect its refractoriness. In the past, it was believed that too coarse particle size would reduce the surface finish of castings.
