“…Since solidification of a casting involves both a change of phase and temperature variable thermal properties, the inverse heat conduction becomes nonlinear. Most of the methods of calculation of timedependent h i existing in literature are based on numerical techniques, generally known as methods of solving the inverse heat conduction problem [13][14][15][16]. IHCP method is based on a complete mathematical description of physics of the process, supplemented with experimentally obtained temperature measurements in metal and/or mold.…”

“…The contact layer is an additional resistance of the flow of heat from the liquid metal to the cold surface. The analysis of the role of the contact layer in a solidification process was recently studied experimentally and theoretically by Loulou et al [10][11][12], by Lipnicki [13], by Lipnicki et al [14] and by Lipnicki and Weigand [15,16]. Beside other things the impact of the contact layer on continuous casting process for thin metal plates is examined in this paper.…”

WpłyW geometrii formy na kształt frontu krzepnięcia przy odleWaniu ciągłymAn analytical model for the transfer has been development and applied for calculating the shape of the solid thickness profile for continuous casting of a thin plate as an example. The stationary solidification front relative to the crystallizer was received from the superposition of the motions of the liquid metal flow in the axial direction and the solidifying metal in the perpendicular direction. The shape of the solidified crust was analyzed for different casting forms. The results are compared and graphically shown for different selected forms.

An analytical heat transfer model has been development and applied for calculating the shape of the solid thickness profile for continuous casting of thin metal rods. The stationary solidification front relative to the crystallizer was received from superposition of the motions of the liquid metal flow in the axial direction and the solidifying metal in the radial direction. The shape of the solidified crust depends on several parameters. The influence of the contact layer between the frozen crust and the internal surface of a crystallizer on the solidification process is also studied. The results are presented as an analytical model and are graphically shown for different selected parameters.Keywords: continuous casting, solidification stationary front, contact layer W pracy bada się analitycznie i oblicza się kształty frontów krzepnięcia przy odlewaniu ciągłym cienkich metalowych prętów. Określono stacjonarny front krzepnięcia względem krystalizatora przez superpozycję dwóch ruchów: przepływu ciekłego metalu w kierunku pionowym i rozprzestrzenianie się frontu krzepnięcia w kierunku promieniowym. Szczególną uwagę zwrócono na opór cieplny warstwy kontaktu między metalem i powiercznią wewnętrzną krystalizatora. Wykazano zależność kształtu frontu krzepnięcia od parametrów termodynamicznych i przepływowych metalu. Wyniki badań wybranych metali przedstawiono w formie graficznej.
