The invention relates to the repair of vessels, particularly refractory-lined vessels such as are used in steelmaking. Frequently there is wear on the lining of such vessels sufficient to prevent the use of the vessel without repair but insufficient to justify the costs of completely re-lining the vessel. The object of the present invention is to provide relatively simple and efficient means (1) for applying particulate refractory material to a vessel (2) wall where required, which objective is met by a means to enable the repair of the refractory lining comprising a rotatable member (4), rotatably mounted at or towards the end of a carrier means (3) adapted to locate the rotatable member (4) at a required position in the vessel, a drive means (6) for the rotatable member, means associated with the carrier to direct and deposit a particulate refractory material on to the rotatable member (4), said carrier and/or said means associated with said carrier being circumferentially adjustable to deposit the particulate material at a predetermined position on the rotatable member and whereby to achieve a required direction of throw of material ejected from the rotatable member. |
