Description
Summary:The article represents a multidisciplinary numerical model for electromagnetic casting of aluminum ingots, as well as the results of its application when casting aluminum ingots diam. 25–30 mm. The numerical model is based on a calculation of the electromagnetic field by solving an additional equation in Fluent combined with the modeling of processes connected with free surface crystallization. The obtained electromagnetic field sources are used in motion and energy equations for solving the magneto-hydrodynamics problem. A solution to the problem of determining the set of technological parameters for ensuring the stable formation of an ingot with the required diameter is provided along with the results of emergency mode modeling. In addition, the article presents the results of applying the established emergency modes at the laboratory casting unit with the electromagnetic mold for the production of ingots using Nikolin and Altsimak experimental alloys as part of ElmaCast® technology.
