    摘要: A device for removing worn nozzle bricks or nozzle linings from the tap holes of metallurgical vessels including a spreading device, which can be introduced into the nozzle brick or tap hole, and a drive for extracting the nozzle brick or lining by means of the spreading device. The spreading device is arranged on a tool holder which can be displaced axially on a support, in particular a carriage. The tool holder can be connected to at least one drive. The tool holder advantageously includes an axial cavity in which a toothed shaft is rotatably mounted. The toothed shaft meshes with the toothing of at least two, and preferably three, spreading jaws which slide radially in the tool holder.
