    HEAT TRANSFER COEFFICIENTS BENEATH THE WATER COOLING NOZZLES OF A BILLET CASTER

  • Original language description

    The accuracy with which the solidification and cooling of a continuously cast billet is investigated depends on the setting of the boundary conditions of the numerical model of the temperature field. An in-house numerical model of the 3D temperature field of a concast billet had been used. This model enables the analysis of the temperature field of the actual blank as it passes through the zero-, primary-, secondary- and tertiary-cooling zones. This paper deals with the derivation of transfer phenomenaunder the cooling nozzles of the secondary zone. These phenomena are expressed by the values of the heat transfer coefficients (HTCs). The dependences of these coefficients on surface temperature and other operational parameters must also be given. Regarding the fact that on a real caster, where there are many types of nozzles positioned inside a closed cage, it is practically impossible to conduct measurement of the real boundary conditions. Therefore, an experimental laboratory device

    Součinitele přestupu tepla pod vodními chladicími tryskami pro sochorové kontilití

  • Czech description

    Součinitel přestupu tepla pod tryskami je dán součtem součinitele nucené konvekce a t.zv. součinitele redukované konvekce odpovídajícímu přenosu tepla radiací. Pro měření chladicích charakterictik trysek bylo vyvinuto speciální laboratorní zařízení. Hodnoty součinitele přestupu tepla jsou ukládány do databáze okrajových podmínek, ze kterých interpolační model stanoví odpovídající hodnotu součinitele pro počítanou povrchovou teplotu, průtok vody a licí rychlost.
