Method and device for repairing a refractory shell of a metallurgical vessel

A method for repairing a refractory sleeve in a metallurgical vessel, which is fitted in a refractory lining of the vessel or in a mechanism, comprising:

• inserting mortar into and then retaining the mortar in a plurality of axially extending mortar spaces of a mortar dispenser that are separated from one another and each having an opening only on a radial outward side and being bound by structure on a radial inward side, on opposed axial ends and on opposed circumferential sides, the mortar being inserted through the open radial outward side;
• inserting the mortar dispenser into a casting channel of the sleeve after the mortar has been inserted into the mortar spaces and while the mortar is retained in the mortar spaces;
• and then
• rotating the mortar dispenser to cause the mortar that has been inserted into all of the mortar spaces and is retained in all of the mortar spaces of the mortar dispenser to be centrifuged at the same time out of the mortar spaces and applied to a length of an inner wall of the sleeve corresponding to a length between the structure on the opposed axial ends of the mortar dispenser, the mortar being conveyed outward from the mortar dispenser into a cavity formed between the mortar dispenser and the inner wall of the sleeve.
