Abstract: The present invention relates to a device for gripping a wearing element of a sliding closure means for metallurgical containers in which the wearing elements are held with gripping in a metal frame by means of rotating members which simultaneously allow the plate to be locked against the frame, the plate to be gripped against the base of the frame and the lateral clearances of the plate in the frame to be absorbed. The gripping devices described are very simple and very robust in design. They contain no screw-threaded parts.

Abstract: A casting tube 8 of a refractory material comprises at its upper end a series of openings for the injection of a protective gas, for example argon, to create an atmosphere which protects the incoming molten metal against oxidation and cools the walls of the casting tube. The injection openings are grooves 11 formed in an upper frustoconical part of the casting tube, whose outer surface defines a fixing collar. These grooves are interconnected by an annular passage 12.

Abstract: A support assembly for a pouring stream protection shroud 1 at the outlet gate of a metal pour vessel comprises an intermediate bearing ring 3 provided between a flange 2 of the protection shroud and a shroud holding ring 4 supporting said shroud at the outlet gate of the metal pour vessel. The holding ring may be provided with cooling gas channels 12, 13, and the bearing ring and holding ring are interlocked by pins 8 extending into a peripheral groove 7 formed in the holding ring and sandwiching a further intermediate bearing ring 16 therebetween. Lubricant may be supplied to the sliding surfaces through peripheral bores 6 and connecting bores 17 formed in the intermediate bearing rings.

Abstract: An arrangement for supporting a refractory plate in the supporting frame of a slide gate for a pouring vessel, whereby the refractory plate is able to oscillate with respect to the supporting frame so as to have its position adjustable to the position of the outlet parts of the pouring system. The refractory plate is shaped with at least one sliding surface on its bottom, on its lower lateral edges or on its lower periphery and, in use, this sliding surface bears on a cooperating sliding surface provided on the supporting frame to allow the refractory plate to freely oscillate with respect to the supporting frame.

Abstract: The invention provides a slide gate device for use on a pour vessel to control flow of molten metal through an outlet in the vessel shell, in which refractory insert plates, conveyed by supporting frames, are introducible into and removable from at least one side of the device, and in which said refractory insert plates are linearly movable in continuous close cooperating contact with a perforated outlet plate for the pour vessel, by applying interdependently coupled moving means to the supporting frame(s) conveying said refractory insert plates, which means transmit an equally distributed effort to each lateral side of said supporting frame(s).

Abstract: A device for replacing pouring tubes at the outlet of a pour vessel for molten metal in which interconnected frames supporting the pouring tubes in a free swiveling manner are guided according to a linear path along the vessel outlet by suitable guiding means, whereby the pouring tube nearing the outlet is brought in close contact with an outlet plate by suitable steering and pushing means.

Abstract: This invention provides a rotary slide gate mechanism for use on a pour vessel to control flow of molten metal through at least one outlet in the vessel shell, whereby refractory insert plates which are conveyed by said mechanism, may be moved in very close cooperating contact with a perforated refractory outlet plate for the pour vessel, so as to control the flow of molten metal therethrough.
