ABSTRACT:
Disclosed is a device for guniting the lining of casting ladles, comprising a platform which is mounted by means of adjustable supports on the ladle to be repaired. On the under side of the platform a guide is mounted so as to extend downward from the platform into the casting ladle. A carriage with a nozzle for supplying gunite onto the surface being repaired is mounted for reciprocating motion along the guide. The guide is fitted on sleds which, in turn, are set on a swivel table so as to permit radial displacement of the sleds relative to the axis of rotation of the swivel table, the swivel table being rotatably mounted on the platform. On the under side of the platform there is also arranged a detachable templet whose curvature is similar to the curvature of the horizontal cross-section of the ladle. A roller pair is mounted on the templet to run around it. The roller pair is coupled with the sleds in such a way that as the roller pair runs around the templet having, for example, on oval shape similar to the oval shape of the horizontal cross-section of the ladle, the sleds are displaced in a radial direction with respect to the axis of rotation of the swivel table. This results in a radial displacement of the guide with the carriage carrying the nozzle for supplying the gunite. The plate of the guide, supporting the carriage with the nozzle moving therealong, has a curvature corresponding to the curvature of the casting ladle lining. Thus, the rotation of the swivel table and the displacement of the carriage along the plate of the guide enable a constant distance between the nozzle fixed on the carriage and the lining of the casting ladle to be maintained.
