Abstract (en)

[origin: DE19744815C1] The heat content and the temperature profile of the slab are calculated by means of a mathematical-physical model, proceeding from the known temperature of the liquid phase at the mold exit, the known physical slab parameters, the convective spreading of the heat within the slab, and the time-dependent inhomogeneous heat transfer to the respective surrounding media. The calculation result, possibly in combination with the measured surface temperature, is used to control the material flow in an existing installation.
