Abstract

CI200 grade cast iron is widely used in industry; however, it cannot be used in very high-stress applications since it is brittle, has low impact toughness, and has a maximum tensile strength of 200 MPa. An examination of the literature shows that there are several ways to improve the mechanical properties of cast iron. The combined impacts of a magnetic field during the solidification process, the inclusion of copper powder in the ladle, and variations in shake-out duration have not been jointly studied, making this experimental inquiry both original and noteworthy. The Taguchi L9 orthogonal array was used to plan the tests and improve the settings for the casting process. Experimental investigation included microstructural analysis and mechanical testing, such as hardness, tensile strength, and impact tests. The Experimental work also used ANOVA analysis to find out how important the process parameters were. The results show that the magnetic field has the greatest effect on the mechanical properties of CI200. The process parameters were optimized to find the best conditions for achieving the desired mechanical qualities. Adding copper also helps the formation of pearlite, which makes the material stronger, and shake-out time makes it tougher. The optimal conditions for achieving the desired mechanical qualities were a magnetic field of 6000 gauss, a shake-out time of 7200 seconds, and a copper content of 1.0 weight %. These three factors together increased the mechanical properties.
