  • Patent number: 5478056
    Abstract: A support device (1) for foundry ladles (13, 14) for a continuous casting plant has a stationary fixed base and a rotary base (4) mounted rotatably with respect to the fixed base and rotatable by means of a rotary drive, on which rotary base at least one support arm system (11, 12) for receiving a foundry ladle (13, 14) is articulated by a parallelogram linkage system (15) with arms (17 to 20) pivotable about horizontal bearing axes (24, 25), with support arm system (11, 12) viewed in outline having a rigid U-shaped support part (26) surrounding a foundry ladle (13, 14) on which part (26) foundry ladle (13, 14) is supportable and can be raised and lowered by at least one pressurized cylinder (16) with respect to rotary base (4).

  • Patent number: 4966349
    Abstract: A supporting arrangement for casting ladles includes a stationarily mounted permanent base and a rotary base rotatably mounted relative to the permanent base. To each rotary base, a supporting bracket system is hinged via a linkage parallelogram system including pivotable guiding rods. Each supporting bracket system is liftable and lowerableby a pressure medium cylinder. In order to reduce the weight of the supporting arrangement and to facilitate any repair work to be done at the pressure medium cylinder, the supporting bracket system is composed of two independent supporting brackets, each supporting bracket independently being hinged to a lower and an upper guiding rod of the linkage parallelogram system. The upper guiding rods of the linkage parallelogram system, on their ends facing away from the rotary base, are united by a cross beam to a rigid unit U-shaped in ground plan.

  • Patent number: 4000553
    Abstract: A continuous casting plant has rollers or rolls for supporting, guiding, bending and straightening or deforming a wide strand, which rollers or rolls have annular recesses distributed over their longitudinal extensions forming bearing pins that are received in two outer bearings and at least one inner bearing arranged therebetween. One of the outer bearings acts as a fixed bearing, while all the other bearings act as expansion bearings.
