Original abstract

The numerical models of solidification are used in the process of steel continuous casting. The main effects on the precise function of this model have the following factors: casting speed, type of steel, the nozzles cooling effect etc. The company ArcelorMittal decided to develop its own model which utilizes measured heat transfer coefficients (HTC) for each nozzle configuration and all operating parameters that occur at the caster. Heat Transfer and Fluid Flow Laboratory from the Brno University of Technology developed its own methodology for measurement and software data processing to find out correct value of HTC for each type and position of the nozzles. These data are used as boundary conditions for the ArcelorMittal's model.

Czech abstract

U kontinuálního lití ocelí se používají numerické modely tuhnutí. Na jejich správnou funkci mají vliv hl. tyto faktory: rychlost lití, druh oceli, chladící účinek trysek atd. Společnost ArcelorMittal se rozhodla vyvinout vlastní model, který využívá naměřené koeficienty přestupu tepla (HTC) pro každou konfiguraci trysek a všechny provozní parametry licí linky. Zjišťováním HTC pro daný typ a pozici trysek se zabývá Laboratoř přenosu tepla a proudění z univerzity VUT v Brně, která vyvinula svoji metodiku měření a softwarového zpracování naměřených dat. Tyto data jsou následně použita jako okrajové podmínky pro model společnosti ArcelorMittal.
