Abstract

An experimental investigation into cold shut formation in, castings has been carried out. Results indicate that cold shuts are formed when liquid metal. Overflowing solid metal, does not completely remelt the solid. As the occurrence of the defect depends upon the thermal energy of the liquid, effective superheat -superheat at which the liquid meets the solid metal is the most important variable affecting the co Id shut formation. This superheat is controlled by both the pouring rate and the superheat at pouring. This paper represents the defect reduction by controlling alloy composition and pouring temperature. The seven quality control methodology is used to analyze and reduce defects which includes check sheet, pare to analysis, cause effect diagram, flow chart, scatter diagram, histogram and control chart.
