Injektorkühlblock for holding at least one injector

The invention relates to a Injektorkuhlblock (1) for mounting at least one injector (2) for introducing a medium into a metallurgical vessel (3), in particular in an electric arc furnace, wherein the Injektorkuhlblock (1) in or on a wall (4) of the metallurgical vessel (3) is arranged, wherein the Injektorkuhlblock (1) has at least one plate (5) in which a through-flow of a cooling medium cooling channel or a cooling hole (6) is arranged, and wherein the cooling passage and the cooling hole (6) has a hot zone (7) from a cold region (8) separates. To be able to detect temperatures or voltages in Injektorkuhlblock better, the invention provides that in the hot region (7) at least one measuring element (9) for measuring the temperature and / or the mechanical stretching is arranged, wherein the measuring element (9) at least comprises a light waveguide (10) integrated in the hot area (7) or at the hot region (7) is fastened.
