Abstract
The characteristics of initial solidification in continuous casting, especially the peritectic phase transition, have a considerable effect on the surface quality, casting productivity, and operational safety. To supervise the thermal behaviour in the continuous casting mould, an online thermal monitoring system has been installed by voestalpine Stahl GmbH. The higher the temperature fluctuation in the mould, the less uniform the strand surface. This significant operational behaviour corresponds with the peritectic region. Differential Scanning Calorimeter (DSC) is a proved method which allows a clear prediction of whether an alloy is peritectic or not. In the following study, a combined investigation of selected steel grades by mould thermal monitoring (= casting behaviour) and DSC experiments (= phase transformations) was performed. This first analysis demonstrates a very high correlation of 95 % (for non-high-Al alloyed steel grades) between the measured phase transformations in the lab with the DSC and the real casting behaviour in industry.
