Abstract: To obtain a short adjustment time with small risk of metal break-out, it is intended during the changing of the dimensions of a continuously cast strand to alter during the casting operation i.e. while the pour or teeming operation is in progress, at least during a time interval of the pivotal movement of the mold wall, the mutual relationship of the displacement speeds of two devices for moving the mold wall and the position of the pivot axis of the mold wall is shifted parallel to its starting position.

Abstract: During the continuous casting of at least two strands, withdrawn with the same speed from the continuous casting molds, the withdrawal speed for both strands should be adjusted in accordance with the quantity of cast metal, typically steel, infed to the first continuous casting mold i.e. also the level of molten metal therein. The infed quantity of steel is regulated in at least one further continuous casting mold as a function of such withdrawal speed or velocity.

Abstract: A method for preventing damage to the strand guide elements of strand guide arrangements or roller aprons of a continuous casting installation for metals, especially steel, wherein it is possible to withdraw a strand which is immobile in the strand guide arrangement or roller apron, by means of a powerful withdrawal unit, without the risk of damaging elements of the strand guide arrangement. At pre-selected locations of the strand guide arrangement there are determined the withdrawal forces effective at such locations and acting upon the elements of the strand guide arrangement. Upon exceeding maximum permissible values the strand withdrawal operation is interrupted.

Abstract: The narrow sides or side walls of a plate mold are adjusted or set, during continuous casting, while increasing their mutual spacing from one another in order to increase the sectional shape or format of the continuously cast strand.

Abstract: An apparatus for the removal, accompanied by simultaneous turning, of cut-to-length hot strand sections from the delivery or run-out roller tables of a multistrand continuous casting installation for steel. The pivot shaft of pivotal levers, provided with receiver or take-up portions for the cut-to-length strand sections, is located below a cooling bed arranged laterally of the delivery or run-out roller tables, approximately at the center between the cooling bed and the roller table located furthest from such cooling bed. By virtue of the foregoing and due to the constructional configuration of the receiving portions or strand section-receivers and a slide or chute operatively associated with the roller table situated closest to the cooling bed, it is possible, with the aid of only one single pivot mechanism or device, to conjointly directly transfer a number of strand sections which are simultaneously turned through an angle of about 90.degree.

Abstract: A method of treating boron-containing steel for continuous casting, especially for teeming or pouring into small sectional shapes or formats with unregulated nozzles. There is introduced into the molten steel located in the casting ladle, by means of an inert carrier gas, in a powder form calcium or a compound thereof, at least one element forming a stable nitride at the melt temperature of the steel and boron or a boron compound. The thus treated steel is protected from renewed reaction with air along its path between the ladle and the continuous casting mold.

Abstract: A method of continuous casting of metals, especially steel, wherein the steel is cast into a continuous casting mold having at least two taper stages or regions which are successively arranged in the direction of travel of the cast strand. In order to accommodate the shrinkage behavior of the forming strand to different casting parameters the bath level in the continuous casting mold is altered within a number of such taper stages or regions.

This alternating field induces a current in the mold wall and a secondary electromagnetic alternating field produced by such current is measured and employed as an input signal for regulation of the bath level in the continuous casting mold.

Abstract: An apparatus for continuous horizontal casting has a vessel for holding the molten metal to be cast. The vessel has an opening in its side which is arranged so that a stream of molten metal issuing therefrom enters a horizontal path. The stream is maintained in a molten state in the upstream end portion of the path and is cooled in an adjacent downstream portion of the path. A mechanism is provided for continuously drawing the strand formed from the stream of molten metal along the path. During the initial stages of solidification, the strand consists of a thin shell of solidified metal surrounding a molten core. The strand tends to sag here and an arrangement is provided for counteracting the weight of the strand. This arrangement includes a connected pair of electrical contacts one of which is immersed in the body of molten metal and the other of which contacts the strand. The arrangement further includes magnets which generate a horizontal magnetic field extending normal to the axis of the strand.
