Abstract

Foundry sand refers to a special sand use in the foundry workshop for either mold making or core making. In-mold making, the sand is used to create a cavity of the pattern in the mold where the molten metal is poured to produce a casting. In core making, the sand is used to bake cores that cannot be obtained directly from the pattern. In this research, Gindiri and Kombun sands were investigated to find their suitability for use as foundry sand. The parameters investigated are chemical composition, cold crushing strength, and bulk density, apparent porosity, firing shrinkage, thermal shock resistance, and refractoriness. The results showed that the sands consists of 62.004% and 54.007% Al2O3, 9.124% and 16.001% SiO2,  2.000% and 4.018% K2O, 1.000% and 1.019% CaO, 0.196% and 0.001% TiO2, 0.019% and 0.907% Fe2O3, 0.006% and 2.014% CuO, 0.007% and 6.017% ClO3, 0.129% and 0.907% ZnO, 0.001% and 0.801% ZrO2, 0.701 and 0.002% PbO, 0.501% and 0.041%NbO, 0.001% and 0.001% As, 0.007% and 0.003% P2, 228.9kg/cm2 and 205.7kg/cm2 cold crushing strength, 1.97g/cm3 and 1.84g/cm3 bulk density, 32.80% and 22.63% apparent porosity, 0.1% and 2% firing shrinkage, 10 and 15 cycles thermal shock resistance and less than 15000C and 14000C refractoriness. The sands are therefore recommended for the production of refractory materials such as ceramics, furnace lining, potteries, and building bricks as well as for the production of mold and core making.
