Original Abstract

Continuous casting machines produce dozens of various steels that are divided into classes according to norms or standards and further sorted into groups with respect to the carbon content. In steel classes, the chemical composition and its allowed range are prescribed and they significantly affect thermophysical properties of steel, e.g. the thermal conductivity, specific heat, density, enthalpy, contractility and viscosity. The chemical composition and its change have also an impact on temperatures of phase and structural changes, e.g. temperatures of solidus and liquidus. The thermophysical properties of steel can be determined by experiments that is, however, in case of many steel grades fairly difficult and expensive, and therefore numerical solidification models are often used. The aim of paper is the study of the chemical composition influence on thermophysical properties of steel as well as on the final temperature field of cast billet for three grades of steel from a particular class having various carbon contents. For this purpose the IDS Solidification Software and the dynamic 3D model of temperature field have been utilized. The results of temperature fields are presented for the 200 x 200 mm billet cast in Železiarne Podbrezová, a.s. The paper demonstrates the software tools developed for described purposes in Matlab and Delphi. The presented study can be utilized for the determination of the chemical analysis precision for numerical models of temperature field and for further optimization of cast billet quality.
