Abstract:
1. A mold for casting metal with a plurality of temperature measuring devices that are arranged in a wall of the mold for determining a temperature distribution in the wall during a casting operation; wherein the temperature measuring devices are arranged in a module with fixed positioning relative to one another and, together with the module, form a structural unit; wherein the module has temperature measuring device recesses in the form of a bore or groove for holding one temperature measuring device each; and wherein the structural unit is mounted in or on the wall of the mold to determine the temperature distribution; wherein the temperature measuring devices are realized as fiber optic temperature sensors, which allow a temperature measurement by the optical time domain reflectometry method or the fiber Bragg grating method; in that the recesses for the temperature measuring devices are formed and arranged in the module in such a way that the fiber optic temperature sensors are arranged in adjacent pairs in the module; and in that the individual fiber optic temperature sensors of a pair are arranged at different depths in or on the module.
