Due to the paste solidification characteristics of nodular cast iron, the defects such as shrinkage cavity and shrinkage porosity are often produced in the production of nodular cast iron. In order to predict these defects before casting production, numerical analogy of casting process has been carried out at home and abroad as early as the printing years. The numerical analogy of casting process is to use the numerical analogy technology to simulate the actual casting forming process in the virtual environment of computer, including the filling process of metal liquid, the cooling and solidification process, the stress forming process, the judgment of the influence degree of main elements in the forming process, the prediction of fabric, performance and possible defects, so as to provide the basis for optimizing the process and reducing waste products.
