Abstract: An installation for continuously casting steel billets comprises a support structure and a guiding roll-rack for the cast billets receiving molten steel from an oscillatory mold and comprising an upper and lower section each having a frame. The upper section and the mold constitute a demountable and replaceable unit. The upper section is supported on the top of the lower section and carries a support for guiding the mold for oscillation. The lower section is mounted on the support structure and carries a mechanism for oscillating the mold. This mechanism comprises an arm mounted for pivoting on the top of the lower guiding device section frame, an actuating rod connecting the arm to the mold for oscillating the mold is response to the pivoting of the arm, and respective pivots connecting the actuating rod to the arm and to the mold, one of the pivots being readily detachable.

Abstract: A semicontinuous casting apparatus comprises a mould positioned above a secondary-cooling chamber which accommodates a dummy bar having a thickened portion and a body made in the form of a hydraulic cylinder intended to pull out a casting and mounted to move lengthwise of said chamber. For the dummy bar to be able to move, the apparatus is provided with alternately actuated index pins. The pins are fixed on stationary mounted legs and extend through openings in the walls of the secondary cooling chamber and cooperate with openings provided in the lateral sides of the thickened portion and body of the dummy bar.

Abstract: Aluminium and other non-ferrous metals are continuously cast in the form of a thin strip in a thickness range of 5-30 mm through an open-ended casting mould. The emerging strip is cooled in conventional manner by direct application of coolant as it emerges from the mould. The novel feature is that the solidified strip is gripped at its side edges at a station close to the exit of the mould and positively pulled out of the mould.

Abstract: Improvement in the method for making metal filament by depositing molten metal onto the peripheral surface of a rotating annular chill roll and separating the solid filament from the chill roll, which involves applying tension to the filament, after it has been separated from the chill roll, along the direction of a tangent to the chill roll past the point at which the filament separates from the chill roll by centrifugal action, to thereby prolong its contact with the chill roll. Apparatus is provided for practice of the method.

Abstract: Installation for manufacturing wire by projecting a jet of electrically conductive metallic liquid through a die into a cooling medium, comprising a crucible equipped with a heating device, a die and an enclosure containing a gas under pressure, an enclosure containing a cooling medium and a wire-receiving device is improved by providing the installation with a thermally and electrically conductive immobile hot piece arranged in such a manner as to debouch into the section of a crucible passageway which is wetted by the metallic liquid, occupies that section and is in contact with a cooling element and with one of the poles of a source of electric current, while an electrically conductive cold piece is connected to the other pole of the source of electric current and assures electrical contact with the jet or the wire.

Abstract: A continuous casting plant has a frame-shaped lifting table, a mould insertable in the lifting table, and a strand guide device following the mould and including strand guide parts. The strand guide part following the mould is surrounded by a carrying frame, and this strand guide part and the carrying frame are installable in and removable from the continuous casting plant together. The carrying frame is arranged with play in the lifting table and is vertically movable therethrough together with the pertaining strand guide part. On the mould and on the carrying frame, supporting faces opposing each other with play are provided and can engage each other when the carrying frame is lifted.

Abstract: Apparatus for producing high-melting-metal-oxide-based crystalline materials by melting a charge under the effect of a high-frequency electromagnetic field with the charge melting zone being maintained constant, the charge being loaded continuously and obtained crystalline material being withdrawn also continuously. The apparatus is a cooled mould, whose body is shaped as a truncated cone with an angle between its generatrix and cone height ranging from 2.degree. to 10.degree., and an induction coil encompassing the body of the cooled mould in the region of location of the constant melting zone.

Abstract: An arrangement for transporting away strand pieces, in particular crop ends cut off in continuous casting plants with a cutting means has a conveying roller path following the cutting device a cut strand discharge apparatus comprised of a plurality of arms pivotable over at least part of their length from a horizontal pick-up position into a tilted dropping position, and a lifting table carrying at least one conveying roller. The lifting table is perpendicularly displaceable relative to the conveying-roller-path plane. An inclined sliding path extending transversely to the strand guide is formed when the lifting table has been lowered and the arms are pressed into the tilted position by the weight of the cut off strand piece.

Abstract: An apparatus is disclosed comprising a strand guide formed by guide plates which are supported and cooled by hydrostatic support elements. The support elements each include a cylinder and a piston which is stressed against the guide plate by pressure fluid supplied to the cylinder. The pistons are each provided with a bearing pad having a plurality of recesses each supplied with fluid at a constant rate which forms hydrostatic support for and cools the guide plates. The forces exerted by the support elements may be controlled by pressure regulating valves in the fluid supply lines leading thereto in response to sensors which sense positional shifts of the guide plates from a set point. The apparatus may also include a controller for the valves which periodically reduces the pressure of the fluid supplied to the support elements sufficiently to allow the casting to move along the strand guide.

Abstract: A continuous casting machine comprising a tundish for pouring molten metal to be cast into a mould, a mould for cooling the supplied molten metal into a billet in a semi-solidified state to be withdrawn downward, and a cooling guide provided immediately beneath the mould and promoting the cooling of the billet emerging from the mould, said cooling guide consisting of cooling guide blocks each urged against each corner of the billet via a spring and having cooling medium intervening between each block and corresponding billet corner.
