Utilization of Response Surface Methodology for the Optimization of Refractory Bricks Production
Shehu M. S.,  Lamido, S. I.,  Nyam, T.
Abstract— This research work was carried out to investigate the application of response surface methodology (RSM) for the optimization of refractive bricks production using Box-Behnken design. The optimum response of refractory bricks produced from local raw materials (clay, kaolin and saw dust) that can retain thermal heat was validated experimentally using the optimum parameters obtained. The produced refractory bricks were characterized at its best optimum condition. The optimum parameters obtained for the refractory bricks are temperature of 870.58 °C, time of 6.5 hrs and composition of 8% sawdust. The ANOVA analysis shows that the model is significant and well represents the experimental data. The characterization of the produced fire bricks show that the firing shrinkage and porosity are 1.67 % - 2.87% and 11.63% - 22.69% respectively while the bulk density decreases with increase in composition (5 - 15%) of saw dust from 1.799 - 2.327g/ m3. The cold crushing strength of the sample without sawdust gave the highest value of 5022.61 KN/m3 while sample with sawdust (8%) gave 3002.87KN/m3.
