<p>An apparatus for supplying fluids to a converter has a rotary joint coupled to a trunnion shaft, one end of the rotary joint being connected to fluid supply pipes and the other end to fluid conduits communicating with tuyeres at the bottom of the converter. The rotary joint comprises a fixed casing and a rotary assembly, that is sealedly and rotatably fitted in the casing and connected to the trunnion shaft. The rotary assembly has a cylindrical member fitting in the casing. A plurality of axially spaced, circular communication grooves are provided in at least one of the internal surface of the casing and the external surface of the cylindrical member. The cylindrical member is provided with a passageway which opens into the communication grooves at one end and into the atmosphere where the cylindrical member emerges outside the casing at the other. The fluid supply pipes are attached to the casing so as to communicate with the communication grooves and the fluid conduits to the exposed part of the cylindrical member so as to communicate with the passageway.</p> |
