The invention relates to a method and to a device for repairing the spout sleeve (6) of a metallurgical vessel which is fitted securely within the refractory lining (4, 5) of the vessel (1). According to the invention the sleeve is repaired by applying mortar to the casting channel (7) of the sleeve (6) with a mortar dispenser (9) that can be inserted into the casting channel (7), which upon removing the mortar dispenser from the casting channel calibrates the latter over the entire length of the channel. The mortar dispenser (9) is driven rotating coaxially to the casting channel (7) during the mortar application and, after a defined time, is removed from the casting channel (7), still rotating. The method is particularly suitable for repairing the inner sleeve of a casting ladle with a slide closure adjoining the ladle spout, maintenance of which is automatically carried out in a maintenance station of the casting facility. In this case the invention makes provision such that the repair of the inner sleeve is also carried out automatically here during the maintenance of the slide closure.
A method for repairing a refractory sleeve in a metallurgical vessel, which is fitted in the refractory lining (4) of the vessel (1) or in a mechanism, characterised in that the repair is carried out by applying mortar to the inner wall (6′) of the sleeve (6) with a mortar dispenser (9) that can be inserted into the casting channel (7), through which the mortar is conveyed to the outside into a cavity (14) formed between the mortar dispenser (9) and the worn inner wall (6′) of the housing (6).
