Patent number: 5611990Abstract: A cooled converter trunnion ring, which is arranged at a distance from the converter, encompasses the converter and is connected to a coolant supply station. In order to achieve good accessibility of the trunnion ring by simple measures and to ensure reliable cooling of the loaded trunnion ring areas with low energy expenditure, a pipe coil, which runs in a largely meandering fashion and through which a liquid coolant flows, is provided on the inner surface of the inner side member substantially facing the converter of the steel mantle of the converter trunnion ring.Type: GrantFiled: June 20, 1995Date of Patent: March 18, 1997Assignee: Mannesmann AktiengesellschaftInventors: Karlheinz Langlitz, Gunter Schmitz

Patent number: 4516757Abstract: A tiltable metallurgical vessel is rotatable about pivot pins which are supported in bearings. At least one of the pivot pins is hollow so that a material carrying conduit can pass through the pivot pin desired materials from a remote source to a desired operational site of the furnace. In addition, other material carrying conduits are provided to the operational sites of the furnace. These latter conduits are connected, at one end, to stationary tapping points and, at the other end, to the operational sites of the vessel. The conduits are guided around (by being coiled by at least one full turn) an enlarged cylindrical portion of the hollow pivot pins.In one embodiment of the invention, the enlarged cylindrical portion of the hollow pins are winding drums which are themselves constructed of symmetrical cylinder halves. In this manner, the winding drum can be easily retrofitted onto a preexisting vessel.Type: GrantFiled: December 9, 1981Date of Patent: May 14, 1985Assignee: Mannesmann AktiengesellschaftInventors: Karlheinz Langlitz, Gunter Schmitz

Patent number: 4491074Abstract: A vehicle for transporting heavy loads on parallel tracks is disclosed. Two of the wheels of the vehicle are fixedly mounted to the vehicle frame, while the remaining wheels are mounted so that they can vertically adjust to deviations in the height of the rail track. In this manner, heavy loads can be transported on the rail tracks without any particular wheel becoming overloaded.In the preferred embodiment, the adjustable wheels are supported by bell crank levers which are themselves connected to one another by a parallelogram linkage arrangement.Type: GrantFiled: January 25, 1982Date of Patent: January 1, 1985Assignee: Mannesmann AktiengesellschaftInventors: Wilhelm Ackermann, Karlheinz Langlitz, Gunter Schmitz

Patent number: 4478102Abstract: A tilt drive is provided for a metallurgical vessel which is mounted on a large sprocket wheel driven by two or more reduction gears. The reduction gears are joined by a torque equalizing apparatus which transmits torque from the pinion of one gear to the pinion of the other, thus acting as a forced synchronizer. The torque equalizing apparatus is effective in both the dynamic and static operations of the drive.Type: GrantFiled: March 19, 1982Date of Patent: October 23, 1984Assignee: Mannesmann AktiengesellschaftInventors: Wilhelm Ackermann, Karlheinz Langlitz

Patent number: 4268014Abstract: A truck is provided for transporting and lifting heavy metallurgical vessels from one place to another. The truck combines two functions ordinarily provided by two different trucks, in that the truck of the invention lifts and/or removes the vessel from its tilting mount for relining and when replacing it on the mount also refits the bottom plate and cover onto the vessel, the latter function usually being carried out by a separate truck. The arrangement includes a separate bottom plate carrying device configured to be positioned on the truck. The carrying device is positioned to be non-displaceable on the lifting mechanism and to be, when thus placed, subject to the centering and lifting mechanisms of the truck of the invention.Type: GrantFiled: January 10, 1980Date of Patent: May 19, 1981Assignee: Mannesmann Demag AGInventors: Karlheinz Langlitz, Gunter Schmitz

Patent number: 4254711Abstract: The invention refers to a transport exchange truck for changing and alternating metallurgic vessels, particularly for steel mill converters. The truck is provided with an interior frame part arranged to rotate in the center of the exterior carriage frame with at least one piston--supportable on the mill floor--of a piston-cylinder unit to raise the exterior frame part carrying the undercarriages. The exterior frame part supports a lift table which can be raised or lowered by means of one or several piston-cylinder units. Each piston rod is connected with the lift table through at least one ball-and-socket joint whose joint housing is provided with articulated traction elements.Type: GrantFiled: August 13, 1979Date of Patent: March 10, 1981Assignee: Mannesmann Demag A.G.Inventors: Karlheinz Langlitz, Gunter Schmitz

Patent number: 4248409Abstract: A plural nozzle arrangement is provided for introducing reactants, additives and so forth to steel manufacturing furnaces, in which a unitary "plug-in" type structure is provided with a plurality of self-contained blast pipes. The arrangement of the invention also provides means for introducing separately additives, reactants or shielding gases around the periphery of the blast pipes as a secondary means of introduction while still contained on the unitary structure. The unitary structure of the invention is so configured that exposure of the periphery of the individual blast pipes to the secondary additives may be varied for different applications.Type: GrantFiled: October 3, 1979Date of Patent: February 3, 1981Assignee: Mannesmann Demag A.G. Wolfgang-Reuter-PlatzInventors: Karlheinz Langlitz, Gunter Schmitz

Patent number: 4215852Abstract: The invention refers to an apparatus for locking a converter tilting gear during a blasting operation, which apparatus is provided with a supplementary gear arrangement to facilitate counterrotation of pinions arranged in pairs versus the pivot pin gear wheel, so that the pinions may be locked and loosened by means of arresting brakes.The arrangement is such that the gear trains for the individual drive pinions can pivot in relation to the position of the pivot pin gear wheel in synchronized fashion to accommodate play between the cooperating gear teeth.Type: GrantFiled: December 20, 1977Date of Patent: August 5, 1980Assignee: DEMAG, AktiengesellschaftInventors: Wilhelm Ackermann, Karlheinz Langlitz, Gunter Schmitz

Patent number: 4096918Abstract: A metallurgical tilting vat, such as a steel mill converter, which, by means of vat extensions or projections, rests on a surrounding tilting mechanism, so that it can be tilted 360.degree., and where radial and axial heat expansion and contractions are accommodated. The tilting mechanism is equipped with dynamic test cells for weighing the vat and/or vat contents. This type of metallurgical tilting vat equipped with weighing devices serves to ascertain the vat contents in order to observe the steel production process based on differing weights of the vat contents, and, in turn, to regulate the decarbonization process based on the weight data and/or data graphs thus obtained.Type: GrantFiled: February 4, 1977Date of Patent: June 27, 1978Assignee: Demag AktiengesellschaftInventors: James Ingram Beggs, Karlheinz Langlitz, Gunter Schmitz, Wolfgang Jansa
