Numerical Simulation of Lost Foam Casting in Special-Shaped Stainless Steel Stirrer
The filling process, solidification process, gasification process and node temperature change of special-shaped stainless steel stirrer via lost foam casting was simulated and analyzed by using ProCAST numerical simulation techniques. The results show that the filling and foam gasification process of stainless steel stirrer casting is a top-down, from the middle layers of outward promotion process. In the filling process, foam pattern gasification and decomposition appeared to be exacerbated by heat transfer in the whole casting. Through the node temperature change over time, it can be conformed to the principles of the order of solidification in the entire stirrer casting solidification process.
