The Evaluation Model Efficiency of Ladle Graphitizing Inoculation of Cast Iron

Abstract:

The model for evaluation of quality of ladle graphitizing inoculation of cast iron, according to the most common technological schemes, using the triple integral, is proposed and implemented. The necessary boundary conditions and parameters of the integral model are presented, described and justified. A concrete example confirms the practical conclusion that graphitizing inoculation of cast iron, melt into a stream in the process of filling a mold, is preferable.
