摘要： A device for connecting a fluid circulating line to a refractory element having a wall provided with a cylindrical bore comprises a gasket intended to be located into the bore and a first supporting element compressing the gasket from the outside of the bore. A second supporting element which can be introduced into the bore sandwiches the gasket together with the first Supporting element and a rod brings the two supporting elements closer so as to compress the gasket. Also, a refractory element, notably a nozzle or pouring shroud, is provided with a cylindrical bore size to receive two supporting elements and a tightening gasket sandwiched by these supporting elements.

摘要： Erosion resistant stopper rod for steel casting having an elongated body of a first refractory material and a sleeve of a second refractory material having elevated erosion resistance characteristics. The sleeve may be copressed with the stopper rod body or separately formed and cemented thereto. The sleeve is positioned around the stopper rod in the region where contact with the slagline occurs. The erosion resistant material of the sleeve is selected from the group consisting of zirconia, magnesia, zirconia-graphite and magnesia-graphite.

摘要： A member of an element for feeding fluid and pasty products in cylinder or sleeve form, able to withstand high thermal transitions, comprises, arranged concentrically relative to each other, a part made of ceramic material (6, 16) intended to come into contact with the fluid and a support made of polymer material (14, 22) overmoulded on the part made of ceramic material (6, 16). The part made of ceramic material (6, 16) has, on its external lateral face, at least one relief (24) comprising at least one dextrogyral helical groove and at least one levogyral helical groove that extend over the surface of the ceramic part in contact with the support made of polymer material which both prevent any relative movement of this part (6, 16) and of the support (14, 22), and distribute the tensions that can be produced by high temperature differentials.

摘要： The invention relates to a device for connecting a fluid circulating line (6) to a refractory element (1) having a wall provided with a cylindrical bore (5a, 5b), comprising a gasket (14) intended to be located into the bore and a first supporting element(13) compressing the gasket from the outside of the bore. A second supporting element (9b) which can be introduced into the bore sandwiches the gasket (14) together with the first supporting element (13) and a rod (9a) brings the two supporting elements closer so as to compress the gasket. The invention also relates to a refractory element (1), notably a nozzle or a pouring shroud, provided with a cylindrical bore (5) sized to receive two supporting elements (9b, 13) and a tightening gasket (14) sandwiched by these supporting elements.
