Heating strategy optimization by means of thermocouple measurements and FEM modelling

Popis výsledku v původním jazyce

This paper deals with comparison of experimentally measured temperature gradient and FEM simulations of two heating strategies that were used for continuously cast blooms soaking. To achieve more relevant results, the bloom contained internal casting defect. Temperature gradient between the continuously cast bloom´s surface and centre was measured by two thermocouples incorporated directly into the bloom. SEM-EDX analysis, hot tensile tests and IDS software was used for modelling of steel thermophysicalproperties with respect to the alloying elements macrosegregation. The model of the continuously cast bloom was programmed in Fortran language. FEM software MARC/MENTAT was used for simulation of two heating strategies. The first heating model was fitted to the commonly used heating strategy when internal defects grown above the critical limit. The second heating model was new proposed strategy that consisted from slower heating up to 1073 K when the first warming-through period occurre
