AFS number was found to be 35.49, 45.52 and 42.39 for silica sand, Fe-Cr and GBF slags respectively. The average PH values of Silica Sand, Fe-Cr and GBF slags were found to be 7.95, 9.89 and 11.40 respectively. 7) The weight loss for silica sand and Fe-Cr slag was found to be 6% and 15% at 1205 OC and 1053 OC respectively; The objective of this investigation is to assess the feasibility of substituting commercial-grade silica sand (CGSS) with granulated blast furnace slag (GBFS) for green mold casting process. Central composite design of response surface methodology (RSM) is used to optimize mold constituents of the GBFS mold. The RSM model Blast Furnace Slag as an Alternative to Silica Sand for A356

Foundry Sand: Charactereistics, Specifications,

AFS-FIRST What is Foundry Sand? • Foundry sand is a high-quality uniform silica sand that is used to make molds and cores for ferrous and nonferrous metal castings. • Foundry sands typically comprise of >80% high-quality silica sand, 5-10% bentoniteclay, 2 to 5% water and less than 5% sea coal.The use of reclaimed sands in the cold-box core room is discussed, comparing three different reclamation processes. The first is called a thermal process that treats resin-bonded sand in a hot fluidized bed. The second is a wet process, removing bentonite and coal dust from green sand with water and attrition treatments. The third is Comparing Sands From Different Reclamation Processes for
