Abstract: 

For practical solution of the problem of determination of dynamics of the smelt solidification in time and prediction of the metal structure (including the calculation and analysis of temperature fields, as well as determination of velocity of the solidification front in time) a mathematical model was developed. The thermal conductivity equation was supposed to be at the basis of this model. Continuous process of pulling the metal layer can be represented as flows of viscous incompressible layer between two elastic-plastic surfaces (rollers), moving with a certain velocity.
