Determination of heat flux layout in the

This paper investigates the heat transfer in the mould of continuous casting and the determination of thermal boundary conditions using a combination of measurements and an inverse numerical simulation technique. We calculate the average heat flux in the mould from the cooling water parameters and derive the heat flux layout at the mould's working surface through an original experimental and numerical simulation procedure. This procedure is founded on measuring the temperatures in the mould walls and solving a numerical inverse problem, which incorporates stress and shrinkage components, utilizing the Procast software package. Additionally, we construct a database of heat flux layouts corresponding to diverse casting speeds and steel chemical compositions, aimed at establishing boundary conditions for online modeling. The successful identification of these factors is crucial for enhancing the quality and safety of production processes in continuous casting. The results contribute valuable insights into heat removal techniques within the casting process and serve as a foundation for further numerical model applications.
