The in-plant thermographic measurement of the temperature conditions on the continuously cast billet surfaces were performed in Štore Steel company by using a high-resolution and a high sensitivity infrared camera. The thermal imaging technique has enabled accurate and detailed insight into some of the mechanisms and processes, which occur during the casting. The analysis was focused on determination of the longitudinal and transversal temperature gradient on the cast billet surfaces. We have compared the measurements with the results of the simulation.
F.13 Development of new production methods and tools or processes
COBISS.SI-ID: 1217787The concept and the structure of multiscale modelling of the continuous casting of steel as well as required software and hardware modifications of the casting device is described in the framework of the invited lecture. We show practical implementation and results on the Štore Steel caster.
F.10 Improvements to an existing technological process or technology
COBISS.SI-ID: 735483The modifications of the continuous casting machine for steel billets, necessary for effective, safe and quality casting is represented first. The simulation system for calculation of temperature field in the billet is shown next. The options of simulation system, which enable the technologist automatic setup of process parameters, are described. The computer systems, based on the simulation system and real process parameters data base are described, which help the technologist in estimation of the reasons for casting defects and suppression of them.

COBISS.SI-ID: 672251A two-dimensional steady-state solution of coupled turbulent flow and heat transfer in continuous casting of steel billets is solved by a new meshless method. The turbulence is considered by the k-epsilon model. The solidification effects on the fluid flow in the mushy region are modeled through the Darcy assumption. The velocity-pressure coupling of the incompressible fluid is performed by the fractional step method. A simulation of the solidification of a spring steel grade in curved mould geometry of the Štore Steel billet caster is performed.
