PCT No. PCT/GB94/01113 Sec. 371 Date Nov. 14, 1995 Sec. 102(e) Date Nov. 14, 1995 PCT Filed May 20, 1994 PCT Pub. No. WO94/29658 PCT Pub. Date Dec. 22, 1994The 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 repair apparatus (1) for applying particulate refractory material to a vessel (2) wall where required, which objective is met by apparatus to enable the repair of the refractory lining comprising a rotatable member (4), rotatably mounted substantially at the end of a carrier (3) adapted to locate the rotatable member (4) at a required position in the vessel, a drive structure (6) for the rotatable member, structure associated with the carrier to direct and deposit a particulate refractory material onto the rotatable member (4), said carrier and/or said structure 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 discharge of material ejected form the rotatable member. |
