This article presents results of a study of the structural and physical inhomogeneity of an ingot used to produce rolled sections.
The temperature of the outside surface of the ingot is measured as the ingot solidifies in the ingot mold and the thermal
efficiency of the hot top is calculated. The data that are obtained show that the ingot must be modernized in order for it
to be used to obtain large sections.
Key words rolled section - ingot - UST defects - hot top - usable outuput - ingot structure - axial defects - temperature fields
