Method and device for repairing the spout sleeve of a metallurgical vessel fitted securely within the refractory lining of the vessel in which the sleeve is repaired by applying mortar to the casting channel of the sleeve with a mortar dispenser inserted into the casting channel, which upon removing the mortar dispenser from the casting channel calibrates the latter over the entire length of the channel. The mortar dispenser is driven rotating coaxially to the casting channel during the mortar application and, after a defined time, is removed from the casting channel, 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. Repair of the inner sleeve is also carried out automatically here during the maintenance of the slide closure.
