摘要：
A device for removing worn nozzle bricks or nozzle linings from the tap holes of metallurgical vessels comprises a spreading device (20), 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 (20) is arranged on a tool holder (9) which can be displaced axially on a suppport, in particular a carriage (8). The tool holder (9) can be connected to at least one drive. The tool holder (9) advantageously comprises an axial cavity (12) in which a toothed shaft (13, 14) is rotatably mounted. The toothed shaft (13) meshes with the toothing of at least two, and preferably three, spreading jaws (20) which slide radially in the tool holder (9).
摘要（中）：
用于从冶金容器的孔中除去磨损的喷嘴砖或喷嘴衬里的装置包括可以引入喷嘴砖或排水孔的扩散装置（20），以及用于通过以下方式提取喷嘴砖或衬里的驱动装置 扩散装置。 扩展装置（20）布置在工具保持器（9）上，该工具保持器可以在支撑件上轴向移位，特别是托架（8）。 刀架（9）可连接至少一个驱动器。 工具保持器（9）有利地包括轴向空腔（12），齿形轴（13,14）可旋转地安装在该轴向空腔中。 齿形轴（13）与在工具架（9）中径向滑动的至少两个，优选三个扩展爪（20）的齿啮合。
