Method for Repairing a Refractory Lining of a Metallurgical Vessel in the Hot State

Abstract

A method relates in particular to the repair of a refractory lining of a metallurgical vessel (10) in the hot state. This repair takes place here by means of an supplying apparatus (15). In addition, recording of at least the worn regions and monitoring of the repair are carried out by means of a device (20). Before, during and/or after the supplying of at least a partial region of the areas (13) of the refractory lining (12) of the vessel (10) to be repaired or the gunning jet (18) is recorded photographically here with visualisation of the temperature ranges (26, 27, 28), and 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 by means of this visualisation of the temperature ranges of the areas to be repaired and of the refractory material during supplying different parameters can be established very accurately, and as a result optimal coating of the wall lining can be achieved.
