| 摘要 |
The invention relates to a device for the secondary and vacuum metallurgical treatment of liquid steel, comprising a vacuum vessel (100), such as an RH, VD or VOD container, which can be sealingly closed for the vacuum process using a raisable and lowerable cover (104) and/or is connected to a sealing forwarding vacuum pipe. On such a device, the seal between the cover (104) and/or the forwarding vacuum pipe and the vacuum vessel (100) is to be improved. In order to achieve this, a sealant (11; 13) is arranged around the circumference at the upper end (12) of the vacuum vessel (100) and/or the vacuum pipe, and the cover (104) and/or a connecting end of the forwarding vacuum pipe is configured with a collar (10) that can be folded over the sealant (11; 13). |
