A method is disclosed for determining at least one geometric parameter of an object comprising a molten component. The method includes determining a relationship between a refractive index of the object and a shrinkage occurring during a solidification of the object. The refractive index and at least one geometric parameter of the object comprising the molten component is determined using a measuring apparatus. At least one geometric parameter of the solidified object from the refractive index and the at least one geometric parameter of the object comprising the molten component is determined using the measuring apparatus and taking into account the determined relationship between the refractive index of the object and the shrinkage occurring during the solidification of the object.

Method for determining at least one geometric parameter of a strand- or plate-shaped object

A method for determining the temperature of a strand comprises disposing the strand along a background radiator of known temperature. Receiving the strand using a spatially resolving thermal imaging sensor in front of the background radiator while the strand is being disposed along its longitudinal axis. Forming an integral across a measuring value area, the integral configured to detect a complete strand portion located in front of the background radiator of the thermal imaging sensor. deducing the temperature of the strand by comparing the formed integral with a reference value.
