Embodiment Construction

[0024] figure 1 The invertible metallurgical vessel 1 shown in is a converter 2 for the production of steel. The container wall 3 is coated with refractory material. The converter 2 is supported by a support body 4 which surrounds the container wall 3 in a U-shape, which support body 4 is referred to below as a support ring.

[0025] The holding of the converter 2 on the support ring 4 is accomplished by an automatic fixing system 9 . The fastening system is here formed on three sides of the converter. One side of the support ring 4 is used for the entry and exit of the converter 2 . For fastening the converter, three support brackets 10 are provided on the vessel wall 3 of the converter 2 , which rest in correspondingly shaped receiving regions 11 of the support ring 4 . in figure 2 with image 3 Details of the automatic fixing system 9 , the support bracket 10 and the accommodation area 11 of the support ring 4 are shown.

[0026] The automatic fastening system 9 com...

Abstract

The invention relates to a metallurgical vessel (1), particularly a converter (2), with support consoles (10) arranged on the wall (3) of the vessel. Said consoles are fixed to a support body (4) that does not fully surround the periphery of the vessel by means of a fixing system (9) which comprises clamping means (12) that engage with the support consoles (10) and can be pivoted into and out of a position of engagement. The vessel (1) can be removed from the support body (4) and can be reconnected therewith when the clamping means (12) are not in a position of engagement. According to the invention, the clamping means (12) comprise a clamping lever (13) which is engaged on one side and which describes a pivoting movement by means of a hydraulic pressure unit (17). According to the invention, the support consoles (10) and a receiving area (11) of the support body (4), which receives the respective support console, are configured in such a manner that they correspond to one another such that the respective support console (10) is guided and fixed in a secure manner even when mechanical and / or thermal movements occur.

Description

technical field [0001] The invention relates to a metallurgical container, especially a converter. Background technique [0002] AOD (Argon Oxygen Decarburization) converters are mostly used in stainless steel production. In the AOD (Argon Oxygen Decarburization) process, process gases (argon, oxygen or also nitrogen) are mixed into the molten bath. Due to the intense process-related dynamic movements of the molten bath in the converter vessel, the refractory lining of the converter is subject to considerable wear and tear, so that the converter lining must be regularly repaired. In order to keep the downtime of the converter as short as possible, it is often practiced to work with changing vessels. In order to be able to replace the converter, it is necessary to release the vessel holder from the support ring surrounding the converter and to disconnect the process gas line and the shielding gas line. [0003] In converters with a charge capacity of more than 80 tons, the...
