A three parametric sensitiveness analysis of the temperature steady state in the mold wall was performed by the finite element analysis. The temperature distribution was studied in the dependence on the wall thickness, heat flow through the wall and on the water film coefficient. The goal of this inverse heat transfer problem was to find generally various heat flows through the long and short cooper mold wall that satisfy the overall heat balance equation and that using the same but unknown water coefficient in cooling grooves of both walls will evoke such temperature at the thermocouple location that corresponds to the experiment. It was necessary to take into account that thermocouples in long mold walls are located at different depths from the outer surface than in short walls and that both walls have different thickness. The gained results proved a good agreement with experimental values. Moreover the inner surface mold temperature was received which is an important input parameter for the temperature calculation of the steel solidification during the concasting process.
