In order to support a steel strand fabricated during a continuous strand casting method, and whose liquid core is agitated or stirred with the aid of an electromagnetic stirrer installed near the strand surface, the stirrer together with guide rolls is oscillatingly moved during the casting operation in the lengthwise direction of the cast strand.

Method and apparatus for supporting a steel strand produced during a

In order to improve disassembly of the oscillation mechanism at a continuous casting installation, the continuous casting mold and the first support guide zone, and at the same time to obtain a support guide arrangement free of dislocation at the transition location, an upper section of the machine base frame and a support frame for the mold and the first zone of the support guide arrangement are at least partially overlappingly arranged. The underside of the frames are supported upon a foundation which is common to such frames. The upper section or portion of the machine base frame at its upper end region and the support frame for the continuous casting mold are movably supported in the direction of travel of the continuously cast strand at a common support location.

Continuous casting installation containing open-ended mold

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., from different run-out roller tables, onto the cooling bed and to further displace the entire stack of strand sections.

Apparatus for removing and simultaneously turning cut-to-length hot

A transfer device for billets or blooms of a multistrand continuous casting installation for metals, especially steel, with associated cutting stations, devices for removing the dummy bar out of the outfeed lines as well as for the storage thereof and a transverse transport device for the cut lengths of the hot strand. The devices for removal of the dummy bars out of the outfeed lines, the storage devices of which are arranged approximately parallel to the outfeed lines and the transverse transport device are dispositioned partially within the cutting paths of the hot strands. The method for operating such transfer device contemplates that after the cut lengths of the hot strands have reached their predetermined lowered position they are initially brought into a preparatory or waiting position between the related outfeed line and the transverse transport device.

Transfer device for billets and blooms of a multistrand continuous

A method of, and apparatus for, starting-up the casting of a strand during continuous casting, wherein molten metal, typically steel, is teemed through a bottom pouring outlet or opening of a tundish at a throughflow rate essentially determined by the dimensions of the pouring opening, into a continuous casting mold. By means of the dummy bar head of a dummy bar there is formed a connection between the dummy bar and the solidified strand forming in the continuous casting mold and after reaching a predetermined bath level in the mold the strand is withdrawn. According to the invention the throughflow rate is maintained smaller during a predetermined time span between the beginning of teeming the metal into the continuous casting mold and reaching the predetermined bath level by melting a tubular-shaped meltable body which has been introduced into the pouring opening, and the melting time of the meltable body is accommodated to such predetermined time span by dimensioning and/or selecting the material of such meltable body.
