A device for exchanging the down spout and repairing a seating brick in a steel ladle, comprising a vertically movable cage, a hoist system therefore and a carriage for transferring the ladle along a fixed track. The carriage is adapted to hold the ladle with the radial direction of the bottom of the ladle towards the down spout at an acute angle to the direction of transfer. Above the path of the upper rim of the ladle, a platform is provided, and further a tower construction is displaceable on the platform in the radial direction towards the down spout. The cage is hoistable inside the tower construction by means of hoisting means connected to the tower construction. In a preferred embodiment the cage consists of a substantially cylindrical insulated wall and of a bottom cooled by flushing with air. A ventilation system, a travelling crab, an operating hatch in the cage wall and a special recessed shape of the cage may facilitate operation. A further improvement may be obtained by the provision of a resiliently mounted pushing device for pushing the down spout out.
