摘要： A refractory ceramic stopper has therein a recess including an annular outwardly enlarged portion defining a stop surface. A stopper rod inserted into the recess in the stopper has a support surface. A plurality of spreadable members having opposite ends are positioned about the stopper rod and are inserted therewith into the recess in the stopper. The spreadable members are spread outwardly such that they enter the enlarged portion of the recess in the stopper with first ends of the spreadable members confronting the stop surface of the stopper and with second ends of the spreadable members confronting the support surface of the stopper rod. Thereby the spreadable members lock the stopper onto the stopper rod.

摘要： A refractory article for casting of liquid melts, especially steel, fabricated from a mixture of Al.sub.2 O.sub.3, graphite, a flux component, a synthetic resin binder and a metallic powder. The flux component contains a first flux with a melting point from 550.degree. to 900.degree. C. and a second flux that becomes active in the mixture in a temperature ranging from 1350.degree. and 1550.degree. C. The refractory article need not be heated before use, and the carbon contained therein, which determines the strength of the article, is retained for a much longer period during use, so that the article will have a long service life.

摘要： The invention resides in a fastening means for a closure plate on a sliding shutter for the outlet of a vessel containing molten metal, whereby the closure plate can be fixed within a supporting frame by the action of releasable gripping means which are provided on the supporting frame and which act on a metal sheath which at least encircles the periphery of the closure plate. The closure plate's external periphery is provided with at least one recess into which the sheath is pressed as a result of the deformation produced by the gripping means. According to an alternative embodiment of the invention, the sheath encircles the exterior periphery of the closure plate as a narrow tension band and is provided with at least one tightener. The desired pretensioning of the sheath and the fixing of the closure plate and sheath to the supporting frame is effected in combination with the tightener.

摘要： An assembly includes a discharge member of a metallurgical vessel and a pipe member connected to the discharge member at mutual surfaces thereof defining a seat therebetween. An annular recess is formed in the region of such seat, a seal seals such seat, and gas is supplied to the annular recess. The seal is in the form of a pair of compressible sealing rings positioned between the mutual surfaces of the two members on opposite sides of the annular recess. A pressure indicator is connected to a gas supply line supplying gas to the annular recess to provide an indication of the pressure of gas prevailing in the annular recess, and particularly of changes of such pressure.

摘要： A closing and/or regulating apparatus for tapping molten metal from the interior of the metallurgical vessel includes an inner refractory pipe having extending through a wall thereof at least one opening and an outer refractory pipe fitted over the inner pipe and having extending through a wall thereof at least one opening. Outer and inner surfaces of the inner and outer pipes, respectively, define mating sealing surfaces. One of the pipes is fixedly mounted to a metallurgical vessel, and the other pipe is movable axially and/or rotatably relative to the one pipe to thereby selectively bring the openings to the two pipes relatively into and out of alignment. The inner pipe has adjacent an inner end thereof at a position inwardly of the opening therein a closure closing the interior of the inner pipe. The outer pipe defines therein a space forming a gas distribution chamber at a location confronting the closure. A gas, for example an inert gas, is introduced into the gas distribution chamber such that the gas passes therefrom between the sealing surfaces and into the openings.

摘要： A closing and/or regulating apparatus for tapping molten metal from the interior or a metallurgical vessel includes a vertical inner pipe having extending through a wall thereof at least one opening for the passage of molten metal. An outer pipe is fitted over the inner pipe and has extending through a wall thereof at least one opening. One of the pipes is to be mounted stationarily with respect to a metallurgical vessel, and the other of the pipes is displaceable relative to such one pipe in a vertical axial direction through a working stroke at which the openings of the pipes may be brought into alignment to thereby discharge molten metal downwardly through the interior of the inner pipe. The dimension of the opening in the stationary pipe in such direction is greater than the dimension of the opening in the displaceable pipe in such direction. The circumferential dimension of the opening in the displaceable pipe is substantially the same as the circumferential dimension of a lower portion of the opening in the stationary pipe.
