DIFFERENCES BETWEEN EXPERIMENTALLY DETERMINED AND CALCULATED LIQUIDUS AND SOLIDUS TEMPERATURES OF LARGE DIAMETER CONTINUOUSLY CAST STEEL

Popis výsledku v původním jazyce

The methods for determination liquidus (TL) and solidus (TS) temperatures in high-temperature region for selected steel grade were compared in the frame of this paper. The paper deals with discussion of the results obtained by the two different simultaneous methods of high-temperature thermal analyses (Direct Thermal Analysis and DTA) on the high-sophisticated specialized experimental systems (Netzsch STA 449 F3 Jupiter, Setaram SETSYS 18TM). The continuously cast steel with large diameter (350 mm) was studied. Based on mentioned dynamic thermo-analytical methods the TS and TL temperatures under different heating/cooling conditions were determined. On large samples (approx. 21 g), the method of Direct Thermal Analysis (DirTA) in conditions of linear heating and cooling was applied. On small samples (approx. 150 mg), the experiments using Differential Thermal Analysis (DTA) under conditions of linear heating were realized. Finally, the data acquired from thermo-analytical measurements were compared with values from calculations by specialized programs (ThermoCalc and IDS software) and with liquidus temperature currently defined in practice of continuous casting of discussed steel grade.
