SUMMARY:Observation of the temperature field on all faces of a slab mold to analyze local heat fluxes
DESCRIPTION:Surface quality of semi-finished products is mainly formed in the mold. Thus, the quality of the slab can be well adjusted by the correct setup of the mold. To be able to analyze the dynamics of solidification of the strand in the mold during the process, fiber optics were implemented in the mold plates of the narrow and broad faces. In total 476 measuring points provide a good monitoring of the temperature field of all four faces of the mold. 
Measurements were carried out using the new fiber optic measurement technology. Local heat fluxes can be determined from temperature measurements, if the geometrical und physical properties of the heat transfer layers in the mold region are known. During the use of measurement technology, process parameters were varied, which lead to a different development of the temperature field. Thus, based on the temperature data, it can be estimated which deformation of the strand shell happen in the mold during casting. At the end, the significance and transferability of measured cold and hot spots in the copper plate for the strand shell is discussed.
