Optimization of Molding Unused New Sand Composition by Mixture Design Method
Abstract
In this study, various parameters which affect the green strength, gas
permeability and shear strength of unused casting sands were investigated in
order to improve the quality of casting sands used in Estaş casting foundry.
These parameters were chosen as water ratio % (X1), coal powder % (X2),
active bentonite % (X3) and unused new sand % (X4).
Mixture design (MD) method was used in the optimization studies. At the end of
studies, the optimum X1, X2, X3 and X4
values, which maximize the compressive
strength (Y1), shear strength (Y2) and gas
permeability (Y3) values, were determined as 3.50%, 6.00%, 6.66% and
83.08%, respectively. Y1, Y2 and Y3 values
were determined as 12.7 N/Cm2, 4.0 N/cm2 and 66 mmWS at
these optimum X1, X2, X3 and X4
values.
