Method for determining the state of a fire-resistant lining of a vessel containing molten metal in particular in which maintenance data, production data, and wall thicknesses at least at locations with the highest degree of wear are measured or ascertained together with additional process parameters of at least one identical/similar vessel after the vessel has been used. The data is collected and stored in a data structure. A calculating model is generated from at least some of the measured or ascertained data or parameters, and the data or parameters are evaluated using the calculating model using calculations and subsequent analyses. Thus, related or integral ascertaining processes and subsequent analyses can be carried out, on the basis of which optimizations relating to both the vessel lining as well as the complete process of the molten metal in the vessel are achieved.

Method for determining the state of a refractory lining of a metallurgical vessel for molten metal in particular

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.
