    Optimization of a Concasting Technology of a Steel Slab via Numerical Models

  • Original language description

    The optimization of production on casters, with the aim of achieving maximum savings and maximum quality of the product is unthinkable without knowledge of the course of solidification and cooling of the slab. It is a global problem of 3D transient heatand mass transfer. If heat conduction within the heat transfer in this system is decisive, the process is described by the Fourier-Kirchhoff equation. It describes the temperature field of the solidifying slab in all three of its states (in the melt, inthe mushy zone and in solid state). In order to solve these it is convenient to use the explicit numerical method of finite differences. Numerical simulation of the release of latent heats of phase or structural changes is carried out by introducing theenthalpy function dependent on temperature. The heat transfer coefficients are a function of the local cooling rate and surface temperature. Based on the results of previous investigations, the boundary conditions are set identically with

    Optimalizace technologie kontinuálního lití ocelové bramy pomocí numerického modelu

  • Czech description

    Optimalizace výroby na licím stroji s cílem dosáhnout maximálních úspor a maximální kvalitu výrobku je nemyslitelná bez znalosti průběhu tuhnutí a chladnutí bramy. Jedná se o nestacionární úlohu přenostu tepla a hmoty. Pro řešení problému je použita explicitní numerická metoda konečných diferencí. Součinitel přenosu tepla je funkcí místní intenzity chlazení a teploty povrchu. Okrajové podmínky jsou stanoveny individuálně pro každou zonu chlazení. Je vyvinut originální 3D of-line model a později on-linemodel, který umožňuje řešení v reálném čase.
