MATHEMATICAL MODELING OF THE CASTING PROCESS OF THE SECOND MERGER.

The paper shows the method of making the equations of the mathematical model that describes the dependence of several mechanical and casting properties on the chemical composition of the cast irons of the second fusion and on the casting conditions. The chemical composition taken into account refers to the contents of C, Si and Mn and the casting conditions analysed were: casting temperature, superheating time and superheating temperature. After performing the specific mathematical calculations, the specific mathematical equations were obtained that describe the dependence of the studied properties according to the parameters of the casting process taken into account.
