Abstract: The jet exiting from jet nozzles is guided along a guide surface for a jet nozzle with one or more nozzle channels disposed next to each other and in parallel, where the hydraulic diameter of the nozzle channels is from about 1.5 to 4 millimeters. In order to limit sharply and without spray the jet exiting out of the jet nozzle crosswise to its axis on the sides and in order to maintain it of uniform width over a large part of its length, the guide surface is of concave shape, the nozzle channels merge without step into the cylindrical jacket surface, the axes of the nozzle channels and the guide surface include an angle of from 0.5 and 2.5 degrees, and the guide surface is provided with a tear-off provision with a cutting edge.

Abstract: A plate mould for continuous casting includes a carrying frame and broad-side walls supported therein and delimiting the mould cavity. Between the broad-side walls, end walls are arranged. The broad-side walls are adjustable normal to the axis of the mould cavity by an adjustment device and clampable relative to each other by a clamping device. In order to enable a perfect movement of the broad-side walls in the direction normal to the axis of the mould cavity, which is simple to maintain and adjust by the maintenance personnel, and to provide an easy installation and removal of the mould insert, each broad-side wall is clampable in the vertical direction by at least one clamp strap, against a holding plate of the carrying frame supporting the broad-side wall. The clamp strap is supported on the broad-side wall and on the carrying frame and clampable against the carrying frame in the manner of a bending carrier by a tensioning device that is detachable from the upper side of the mould.

Abstract: A plate mould of a continuous casting plant includes a carrying frame mounted on a reciprocating mould lifting table, and walls supported on the carrying frame and delimiting the mould cavity. At least one of the side walls is displaceable transversely to the mould axis by an adjustment drive to change the format of the strand cross section. In order to reduce the expenditures in terms of machinery and investments for a continuous casting plant, the adjustment drive is arranged on a stationary supporting structure neighboring the lifting table, or on the lifting table, and is in connection with the adjustable side wall via a coupling.

Abstract: In a supporting and guiding arc for cast strands including rollerways supporting the strand on opposite sides, the rollers are mounted on one-piece arcuate longitudinal carriers extending over the total length of the guiding arc. Transverse carriers are arranged in pairs opposite each other along the arcuate longitudinal carriers at a distance from one another, engaging the arcuate longitudinal carriers from behind and being connected by drawing anchors. In order to combine the advantages of guiding arcs assembled of segments arranged in series with the advantages of guiding arcs equipped with continuous arcuate longitudinal carriers, each rollerway has only two arcuate longitudinal carriers. A plurality of supporting segments are inserted between the arcuate longitudinal carriers and are detachably fastened to the same. A plurality of rollers allocated to a rollerway are journaled on each supporting segment.

Abstract: A guiding stand to be used in a continuous casting plant includes rollers supporting the strand at opposite sides and arranged in a supporting framework. The rollers, at least at one side of the strand, are mounted in guide rods pivotably arranged in the supporting framework for adjustment to various strand thicknesses. The guide rods are pivotable by an adjustment device, and the guide rods of neighboring rollers are each connected with one another by coupling rods in the manner of a four-bar linkage.

Abstract: A continuous casting mould suitable for adjustment to various strand cross sectional formats, has at least one transversely divided side wall whose parts are displaceable and fixable relative to the opposite side wall by adjustment drives and are articulately connected with one another, the axis(es) of the connecting member(s) extending in the horizontal direction over the width of the side wall; a method of changing the cross sectional format of a strand.

Abstract: An arrangement for adjusting and securing a bottomless mould to a mould lifting table in a continuous casting plant for strands with supporting and guiding paths arranged to follow the mould to support the strand at opposite sides thereof, has centering apparatus on the mould lifting table and on the mould. Part of the centering apparatus is vertically displaceable relative to the supporting and guiding paths. The mould is arranged with lateral play relative to the mould lifting table and bracing devices are provided for fixing the mould on the mould lifting table.

Abstract: A plate mould with a rectangular cross-section for continuously casting steel slabs has end walls that are tiltably adjustable and two adjustment drives at each end wall and link plates connecting each end wall and its pertaining adjustment drives in a four-bar-linkage manner.

Abstract: A plate mould for continuously casting steel has a carrying frame, and side and end walls with cooling devices. At least one side wall is movable transversely relative to the mould by separate apparatus. The end walls are each comprised of a holding plate, a supporting plate and a cooled copper plate and can be clamped between the side walls by spring clamping elements. Wedge-shaped noses are provided on the upper and lower edges of the supporting plate for engagement with a wedge-shaped groove in the pertaining holding plate and with a clamping piece, respectively.

Abstract: A roller stand to be used in continuous casting plants comprises two strand guide parts arranged opposite each other so as to guide the strand between them, which strand guide parts are held together by drawing anchors. The roller carrying means of one of the strand guide parts are movable relative to the strand by piston driving means. Overload protection means are provided within the area of the piston driving means and spacers maintain the distance between the opposing rollers.

Abstract: A strand guiding apparatus to be used in a continuous casting plant has a frame for the supporting devices of the strand, which frame is actuated by an adjustment means having a displacement ruler detachably connected to the frame by means of a quick lock. Upon release of the quick lock and retraction of the displacement ruler, the frame can be removed vertically upwardly.
