Numerical simulation analysis is of great significance to optimize the sand coated casting process of iron mold. Although the numerical simulation results are verified by experiments, this paper only makes a qualitative analysis. The experimental verification method does not quantitatively describe the consistency between the filling process and the numerical simulation results. Further research on the quantitative description of experimental verification is needed in the future.
As cast ductile iron will be more and more widely used in all walks of life in the future. Its market prospect is broad and its economic benefits are very significant, which will promote the sound and rapid development of the casting industry. The key to ensure the quality of castings is to strictly control the production process.
The possibility of stable production of as cast qt800-3 crankshaft without adding alloy elements is analyzed. Lack of sufficient verification of mass production. In the future, it is necessary to adjust the production process on the premise of paying close attention to the casting quality in production.
