Abstract
Mould properties and its control is a section in foundry industry that has to be dealt with prior importance during the making of moulds. The property of the mould sand and mould plays a key role in determining the quality of the casting. There are several important properties associated with these such as moisture content, permeability, compatibility, combustibility, mould hardness, tensile strength, shear strength, transverse strength, compression strength etc. This work is aimed at optimizing the CO2 sand mould properties using Taguchi method with the help of MINITAB software. A multi-response optimization method is intended to be followed. For that three input parameters and three output parameter are taken for CO2 sand. All the three output parameters will be optimized individually. The input process parameters selected for CO2 sand are AFS (Average Fineness of Sand) number, percentage of yellow dextrin content and percentage of sodium silicate content at three levels, and the output parameters selected are permeability, dry compression strength (DCS) and dry shear strength (DSS). An L9 orthogonal array will be used for carrying out experiments for optimizing each of the output parameter.
