摘要：Most severe problem that foundry industries always face named casting defects especially „porosity‟,since it‟s occurrence is 82% among all in case of our research. This paper presents the experimental analysis andinvestigation of groove porosity occurred near the groove on brake disc. This paper reflects the research done in AshtaLiners Pvt. Ltd. Ashta for reduction in rejection of casting due to groove porosity defect. This is achieved by alteringthe casting parameters like binder ratio, casting temperature, addition of Titanium, Zirconium as inoculant and Ironoxide. Result obtained shows that the additions of 0.25% red iron oxide, 0.3 to 2.5% Titanium and 0.5 to 2.5%Zirconium are surprisingly more effective as compared to others in eliminating porosity. Use of core coating by Ironoxide results in reduction of porosity occurrence. The results obtained in this research will help metal casters to reduceporosity defects in grey iron castings.
