A continuous casting mold comprising an oscillating supporting structure including side walls defining a mold cavity, together with the supporting structure, is supported on a lifting table oscillated by an oscillation drive and guided in the oscillation direction by a guiding device. In order to keep the oscillating masses as small as possible and to improve the space conditions below the mold as well as to ensure easy repair, the lifting table is formed by at least two oscillating beams arranged at a distance leaving free the horizontal dimensions of the mold cavity and bridged by the supporting structure including the side walls.

A method for adjusting the casting width of a continuous metal, in particular steel, casting mold in which two displaceable end walls are clamped between two large side walls with a predetermined clamping force. Prior to making the adjustment the clamping force acting on the end walls is released and one large side wall is displaced away from the abutting end walls to form a gap between them so that the end walls can be moved to the desired position. They are then clamped again between the two side walls. To attain an optimum gap width between the end and side walls by taking the actual mold dimensions at the time of adjustment into consideration, the thermal expansion of the end walls in a direction parallel to the axis of the tie rods is measured during casting, or at least during the start-up period of the continuous casting process until it has reached its equilibrium state. The adjustment is the made by adding the desired, optimum gap width to the actual, measured expansion of the end walls.

In order, in a guide roller for continuous-casting plants, which is formed by a plurality of aligned roller portions, to avoid the creeping movements of the guide roller in the axial direction and thermally induced distortions in it, it is proposed that a roller portion adjacent on both sides of roller portions either be provided at its two ends with roller journals carrying support bearings, and these roller journals engage into recesses of the adjacent roller portions, or be provided at its two ends with recesses, and roller journals, having support bearings, of the adjacent roller portions engage into these recesses.

An arrangement for exchanging supporting or driving rollers of a continuous casting plant with a strand guide including two oppositely arranged roller ways includes a sled that is movable between the roller ways for transporting a roller to and away from a bearing place in one of the roller ways. The sled is equipped with roller seats receiving the rollers and includes means for moving a roller from its bearing place to the sled and from the sled to the bearing place. The roller seats are arranged on the sled so as to be movable transversely to the longitudinal direction of the rollers and they are movable by means of an adjustment device out of a transporting position retracted in the sled into an engagement position projecting out of the sled.

An arrangement at a continuous casting plant includes a liftable and lowerable tundish mounted on a movable carrier and a tilting device mounted on a tilting stand for emptying of the tundish. The tilting device includes a tilting beam rotatable about its longitudinal axis and the tundish possesses recesses at its lower side, corresponding to the cross section of the tilting beam. Thus the tundish is lowerable at the tilting stand so its recesses make a positive connection with the tilting beam.

In a supporting and guiding means for continuously cast strands including a plurality of exchangeable supporting elements each provided with rollers at opposite sides thereof, neighboring supporting elements are provided with shoulder-like projections where they are separated from each other. The projections are oppositely arranged, back each other, and carry one roller each so as to complement each other to form a pair of oppositely arranged rollers.

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. The cross beam is supported on the pressure medium cylinder by a swivel arranged in alignment with the hinges of the upper guiding rods, which hinges are arranged on the ends facing away from the rotary base.

A bow-type continuous casting plant includes a strand bending arrangement arranged below the mould, and a circular-arc guide for the strand following thereupon. The circular-arc guide has oppositely arranged supporting roller ways, and the bending arrangement includes two oppositely arranged bow-structure parts carrying bending and supporting rollers each, and being supported on each other. The distance of the supporting-roller ways of the circular-arc guide is variable in accordance with the strand cross section to be adjusted. One of the bow-structure parts of the bending arrangement is provided with exchangeable roller carriers detachably fastened to it and adapted to different strand cross-sectional formats with their dimensions.

A supporting and guiding stand for a bow-type continuous casting plant comprises exchangeable supporting segments in which the rollers of the oppositely arranged inner and outer guideways are mounted at a distance from one another. The segments are supported on a carrying frame, which advantageously is dividedly designed. On each segment at least one rim-side roller of the outer guideway is detachably fastened to the segment.

A strand guide for a continuous casting plant includes oppositely arranged rollers for supporting and guiding the strand. The axes or shafts of the rollers are detachably fastened to longitudinal carriers of a strand guiding stand. The longitudinal carriers are arranged between holding means supporting the axes of at least two pairs of oppositely arranged rollers, and the holding means of these oppositely arranged rollers are clamped relative to each other by centrally positioned clamping means.
