Abstract
A method for repairing a refractory lining of a metallurgical vessel in the hot state. This repair takes place using a supplying apparatus. In addition, recording of at least the worn regions and monitoring of the repair are carried out by a monitoring device. Before, during and/or after the supplying of material, at least a partial region of the areas of the refractory lining of the vessel or the gunning jet is recorded photographically with visualization of the temperature ranges. This results in an evaluation with regard to different parameters such as properties, layer thickness and/or distribution of the supplied material. It has been demonstrated that visualization of the temperature ranges of the areas to be repaired and of the refractory material during supplying of material enables different parameters to be established very accurately, and as a result, optimal coating of the wall lining can be achieved.
