Control of Solidification Process and Surface Microstructure of Large Size Ingot ZALCu5MnA Alloy

Abstract:

Compared with conventional ingot, difficulties in melting and casting of large size ZALCu5MnA alloy is due to the increase of ingot size, which lead to a depth increase in smelting bath process, mixing melting liquid is also difficult, and chemical composition of molten pool is not uniform. this paper uses finite element method to analyze the temperature field and thermal stress field of large size ingot of alloy in solidification process, heat transfer model, radiation the boundary condition and latent heat of solidification processing are discussed meanwhile the microstructure of the casting parts surface and center are related researched.
