Sažetak
The object of this paper was to examine the structural defects that influence the mechanical properties of circular cross-section continuous steel casting (API N80) intended for the rolling mill production of the seamless tubes. The mathematical model of heating process of steel load in the rotary-hearth furnace, which enables the required thermal analysis, was constructed on the basis of the finite element method (FEM). Transient heat conduction and thermal stress analysis were performed in order to determine the heating rate and, via the temperature variation throughout the structure, thermal stresses and deformations.
