Abstract: A device for the continuous casting of metal includes a lifting platform which can be driven in an oscillating fashion by a drive device, a continuous casting mold received on the lifting platform, and a stationarily arranged support frame provided with guiding or bearing elements for the lifting platform. The guiding or bearing element is an elastic spring system including two spring legs arranged angularly relative to one another and extending perpendicularly to the oscillation direction. The two spring legs are formed like a tuning fork and respectively overlapping upper and lower ends of the two spring legs form the support surface for the lifting platform or the connecting surface with the stationarily arranged support frame. The spring system, in addition to the force in the oscillation direction, compensates by load balancing disturbing forces in directions perpendicular to the oscillation direction.

Abstract: The invention relates to a method for controlling the temperature of a melt (10), preferably of a steel melt, in a distributing vessel (11), whereby the temperature of the melt is measured, the measured result is compared with a predetermined temperature range in the form of specified values, and as much heat is supplied or withdrawn from the melt such that the temperature remains inside said range. In order to control the melt temperature, a fireproof shaped part (20) which is closed on both sides and which is provided for accommodating a liquid cooled induction coil (1) is immersed in the melt (10). The transmission of heat is carried out by means of thermal conduction out of the wall of the shaped part (20) which is coupled to the induced electromagnetic field and/or by means of a direct coupling to the liquid melt (10).

Abstract: A method of descaling surfaces having oscillation marks of cast billets produced by a continuous casting process an reduced in a hot strip train including an equalizing furnace and a plurality of rolling mill stands, with the cast billets being delivered from a continuous casting machine through a billet guide, with the method including subjecting surfaces of a cast billet, in a limited region between an end of the billet guide and an entrance of one of the equalizing furnace and a first rolling mill stand, by at lease a double deflection of the cast billet from a horizontal transporting path of the cast billet, to stretching in a region of each deflection, and subjecting the surfaces of the cast billet to an intensive flushing with hard water jets in the deflection regions of the eight-gage slab.

Abstract: A device for the continuous casting of steel includes a continuous casting mold which oscillates in the casting direction, wherein the continuous casting mold is arranged in a lifting table of a stationary base frame, wherein the lifting table is connected to an oscillating drive, and wherein guide elements are provided for the lifting table on both sides transversely of the casting direction. The guide elements are constructed as plate-shaped frames with transverse struts and always two plate-shaped frames located opposite each other and at a distance from each other are combined to form a pair of plate-shaped frames, wherein each plate-shaped frame is connected to the base frame, on the one hand, and to the lifting table, on the other hand.

Abstract: A metal mold for continous casting of steel bands and including wide side walls and opposite narrow side walls extending parallel to each other between the wide side walls, and displaceable toward each other and away from each other for adjusting a distance therebetween, with the wide side walls each having a concave arcuate portion defining a pouring region, and inclined surfaces on opposite sides of the concave arcuate portion.

Abstract: A method of forming a wide side wall of a chill mold for a thin slab casting installation and which has a bulged widened region proceeding from the upper edge of the wall and terminating toward the sides and toward the bottom of the wall, includes making the wall of copper with a thickness of 5-50 mm, and forming the bulged widened region under tension or a combination of tension and compression conditions.The apparatus for performing the method includes a bottom plate die with an appropriate contoured face, and a power-operated upper die the end face of which is shaped to match desired bulge of the widened region of the wall and cooperates with the contoured face of the bottom die plate to form the widened region.

Abstract: A pouring tube for feeding molten steel into the pouring zone of a continuous casting mold includes a tube portion connected to a pouring container and an end portion provided with a bottom piece. To ensure safe operation of the pouring tube and an improved flow distribution, the bottom piece has in the direction of outlet openings thereof a width which is smaller, between 30% and 80%, than the distance between the walls which form the upper limits of the outlet openings.

Abstract: Means are provided for connecting the proximal end of a dummy strip to the distal (i.e. leading) end of a strip casting, in which a throw-away element serving both as a connector and a heat sink for chilling the metal adjacent to the connector is removably mounted on the proximal end of the dummy strip, with a slightly resilient sealing element holding both the dummy strip and the connector-heat sink element centrally of the mold cavity, and with the connector-heat sink spaced from the walls of the mold by a narrow gap and also having means for both chilling and positively interlocking with the metal of the distal end of the cast strip when it congeals.

Abstract: A continuous casting apparatus has a casting platform which supports a mold defining two casting passages. A laterally undivided roller guide is disposed below the mold. The apparatus further includes a pair of dummy bars, and a carriage on the casting platform for storing the dummy bars. When a casting operation is to be performed, each dummy bar is lowered into the roller guide via a respective casting passage so as to seal the lower end of such passage. At this time, the dummy bars are spaced from, and are generally parallel to, one another. Since the roller guide is laterally undivided, the roller guide is unable to maintain the spacing between the dummy bars as the latter are withdrawn from the roller guide during casting. Accordingly, distancing means is provided to keep the dummy bars spaced from one another.

Abstract: A flat jet nozzle for spraying coolant on a continuously conveyed billet with a wide angle spray along the width of the billet is formed with a cylindrical wall having a discharge slot extending in the circumferential direction of the cylindrical wall, with the slot having a width which increases from the middle of the slot toward the outer sides thereof.

Abstract: A guiding device for an oscillating continuous casting mold includes a spring holder connected at a central area to a frame of a continuous casting plant, and a spring which is clamped in a bridge-like manner at its both extremities to the spring holder and is connected to the mold lifting platform via an intermediary part.

Abstract: The apparatus for spraying a mixture of a propellant and a cooling agent onto a continuously cast strand, especially slabs, comprises guide means for the cooling agent including a spray nozzle, having a nozzle opening at the front side thereof in order to improve the cooling agent distribution. A narrow mixing chamber flow communicates with the spray nozzle and opens transversely with respect to the strand and with the formation of an angle. The spray nozzle opens approximately at the apex region of the mixing chamber. The cooling agent is discharged as a spray jet from the spray nozzle and gaseous propellant is conducted from a number of sides at an acute angle to the direction of the spray jet.

Abstract: A vertical continuous casting mold has a pair of wide walls, and a pair of narrow walls which are received between the wide walls. The narrow walls are translatable back-and-forth, and also pivotable, in order to change the width of a strand cast in the mold. Each of the narrow walls is driven by an arrangement which permits the respective narrow wall to be remotely adjusted during casting. The arrangement for each narrow wall includes a pair of internally threaded sleeves which are respectively articulated to an upper and a lower portion of the corresponding wall. A rotatable spindle is threaded into each sleeve. The spindles are operative to cause axial displacement of the associated sleeves in response to rotation of the spindles. The two spindles for each narrow wall are rotated by a common motor. A first transmission transmits motion from the motor to one of the spindles, and a second transmission transmits motion from the motor to the other spindle.
