Abstract: In this paper, attempts are made to optimize process parameters in CO2 Moulding sand of co2 casting process using response surface methodology. Three independent process parameters AFS number of moulding sand, percentage of sodium silicate and percentage of dextrin powder are selected to assess the co2 moulding process process performance in terms of sand permeability number and dry compression strength (kg/cm2).To plan and analyse the experiments, Response Surface Methodology (RSM) employing rotatable central composite design (CCD) is used. The relation between input process parameters and response variables is studied with the help of contour plots obtained by the use of RSM. For each response, Analysis of Variance (ANOVA) is done to study the influence of each process parameter. ANOVA is carried out within 95% of confidence level (p-value ≤ 0.05). It is found out that AFS Number and percentage of sodium silicate are significant parameters for dry compression strength. It is also observed that the linear terms, AFS number and percentage of sodium silicate along with quadratic term percentage of sodium silicate × percentage of sodium silicate are significant to permeability.
Keywords: Co2 moulding, dry compression strength, permeability.
