| Abstract: | The sealing wall plate is a casting with complicated construction and thin section,the crack-ing is the defect often taking place in casting production process.By decreasing the grade of cast iron,using furan resin selfsetting sand as a substitute for clay sand to make the core and prolonging cooling time in mould,the cracking problem has been solved. |

| Keywords: | cracking defect cast iron grade furan sand cooling time in mould |
