  • Patent number: 5364079
    Abstract: A tiltable converter arrangement is disclosed in which a converter vessel is supported by a carrying ring surrounding and spaced from the converter. The carrying ring includes two diametrically oppositely arranged carrying trunnions. The converter is supported within the carrying ring by a plurality of guide rods, the converter being movable in the upright position. Each of the guide rods is designed as a pendulum rod each have a first end and a second end in which the first end is connected to the carrying ring by means of a spherical bearing and the second end connected to the converter vessel also by means of a spherical bearing, such as to provide an articulate universal joint between the carrying ring and the converter vessel.

  • Patent number: 4775134
    Abstract: An arrangement for preheating scrap includes a scrap treating furnace into which at least one exhaust gas duct from a metallurgical furnace enters. In order to attain a higher efficiency in preheating, the scrap treating furnace has a through chamber for a plurality of adjacently arranged or superposed scrap receiving vessels. Each of these vessels is provided with its own gas inlet opening and with its own gas exit opening. The scrap treating furnace also includes a charging means on one end of the through chamber to receive at least one scrap receiving vessel and a discharging means on the other end of the through chamber to receive at least one scrap receiving vessel. A conveying means for moving the scrap receiving vessels in cycles from the charging means to the discharging means as well as gas conducting means for connecting the gas exit openings with the gas inlet openings of neighboring scrap receiving vessels are arranged within the through chamber.

  • Patent number: 4281823
    Abstract: In a tiltable converter arrangement with a carrying ring surrounding the converter vessel at a distance and having two carrying trunnions, the converter vessel is movably connected with the carrying ring by articulately connected brackets. The converter vessel is mounted in the carrying ring by means of three of these brackets that are inclined towards the longitudinal axis of the converter vessel and whose joints are each mounted to the converter vessel and to the carrying ring. The three brackets are pivotable in the plane laid through their longitudinal or central axes and the longitudinal axis of the converter vessel, which plane is at a right angle to the axis of the carrying trunnions.

  • Patent number: 4280688
    Abstract: A tiltable converter vessel is supported on a carrying body arranged about its shell by means of lug pairs accommodating bearing forces, the lugs of each lug pair being arranged opposite each other on both sides of the carrying body. At least one lug of each lug pair is supported on the carrying body by at least one piston-cylinder unit whose piston is hydraulically adjustable in the longitudinal direction of the converter vessel. At least one further piston-cylinder unit is arranged parallel to the extension of the carrying ring.
