A metallurgical vessel includes first and second tuyeres for respectively delivering process materials above and below the level of molten metal contained within the vessel. Coupled to one of the trunnion pins which support the vessel for pivotal movement about a horizontal axis is a rotary joint which defines a plurality of concentric flow paths for transporting cooling liquid to the vessel and process fluids to the first and second tuyeres. The passages are provided by a first plurality of coaxially spaced apart annular fixed members and a second plurality coaxially spaced apart annular members mounted on the trunnion pin and rotatable therewith. At least some of the plurality of members have portions which define lateral flow paths interconnecting one of the concentric flow paths. One of a plurality of first pipes are connected to each of the lateral flow paths defined by the first members and to sources of cooling liquids and process materials respectively and each of a second plurality of pipes are coupled to one of the second plurality of lateral flow passages defined by the second members and to the vessel support or to the first or second tuyeres. |
